Paul Menzel 1b3e176468 x86 I/O APIC: Dump I/O APIC regs in `ioapic.c`
Some southbridges have code in their `lpc.c` files to dump the
I/O APIC registers.

    printk(BIOS_SPEW, "Dumping IOAPIC registers\n");
    for (i=0; i<3; i++) {
            *ioapic_index = i;
            printk(BIOS_SPEW, "  reg 0x%04x:", i);
            reg32 = *ioapic_data;
            printk(BIOS_SPEW, " 0x%08x\n", reg32);
    }

Add similar code to `src/arch/x86/lib/ioapic.c` so all boards using
the function `set_ioapic_id()` get the debug feature and the other
boards can be more easily adapted in follow-up patches.

The old approach was to invalidate the entire TLB every time we set up
a table entry. This worked because we didn't turn the MMU on until
after we had set everything up. This patch uses the TLBIMVAA wrapper
to invalidate each entry as it's added/modified.

Aaron Durbin bebf66909a x86: use boot state callbacks to disable rom cache
On x86 systems there is a concept of cachings the ROM. However,
the typical policy is that the boot cpu is the only one with
it enabled. In order to ensure the MTRRs are the same across cores
the rom cache needs to be disabled prior to OS resume or boot handoff.
Therefore, utilize the boot state callbacks to schedule the disabling
of the ROM cache at the ramstage exit points.

It's helpful to provide a distinct state that affirmatively
describes that OS resume will occur. The previous code included
the check and the actual resuming in one function. Because of this
grouping one had to annotate the innards of the ACPI resume
path to perform specific actions before OS resume. By providing
a distinct state in the boot state machine the necessary actions
can be scheduled accordingly without modifying the ACPI code.

David Hendricks 1fb11d105b armv7/exynos5250: Deprecate sdelay in favor of udelay
This gets rid of the clock-tick based sdelay in favor of udelay().
udelay() is more consistent and easier to work with, and this allows
us to carry one less variation of timers (and headers and sources...).

Every 1 unit in the sdelay() argument was assumed to cause a delay of
2 clock ticks (@1.7GHz). So the conversion factor is roughly:
sdelay(N) = udelay(((N * 2) / 1.7 * 10^9) * 10^6)
          = udelay((N * 2) / (1.7 * 10^3))

The sdelay() periods used were:
sdelay(100) --> udelay(1)
sdelay(0x10000) --> udelay(78) (rounded up to udelay(100))

There was one instance of sdelay(10000), which looked like sort of a
typo since sdelay(0x10000) was used elsewhere. sdelay(10000) should
approximate to about 12us, so we'll stick with that for now and leave
a note.

Ronald G. Minnich c0b972f60d Exynos5250: add a microsecond timer
Add a microsecond timer, its declaration, the function to start it,
and its usage.  To start it, one calls timer_start().  From that point
on, one can call timer_us() to find microseconds since the timer was
started.

We show its use in the bootblock. You want it started very early.

Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.

We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

David Hendricks 086b369dfc armv7: replace read/write macros with inlines
This enables type checking for safety as to help prevent errors like
http://review.coreboot.org/#/c/3038/ . Now compilation fails if the
wrong type is passed into readb/readw/readl/writeb/writew/writel
or other macros in io.h.

This also deprecates readw/writew. The previous definition was 16-bits
which is incorrect since wordsize on ARMv7 is 32-bits and there was
only 1 instance of writew (#if 0'd anyway). Going forward we should
always use read{8,16,32} and write{8,16,32} where N specifies the
exact length rather than relying on ambiguous definition of wordsize.

Since many macros relied on __raw_*, which were basically the same
(minus data memory barrier instructions), this patch also gets rid
of __raw_*. There were parts of the code which ended up using these
macros consecutively, for example:
	setbits_le32(&regs->ch_cfg, SPI_CH_RST);
	clrbits_le32(&regs->ch_cfg, SPI_CH_RST);

In such cases the safe versions of readl() and writel() should be
used anyway.

Note: This also fixes two dubious casts as to avoid breaking
compilation.

Aaron Durbin 5a767fdfcb x86: dynamic cbmem: fix acpi reservations
If a configuration was not using RELOCTABLE_RAMSTAGE, but it
was using HAVE_ACPI_RESUME then the ACPI memory was not being
marked as reserved to the OS. The reason is that memory is marked as
reserved during write_coreboot_table(). These reservations were
being added to cbmem after the call to write_coreboot_table(). In
the non-dynamic cbmem case this sequence is fine because cbmem area
is a fixed size and is already reserved. For the dynamic cbmem case
that no longer holds by the nature of the dynamic cbmem.

the .rel.textfirst section entries were not being included in

The ramstage is now linked using an intermediate object that

The rmodule code was developed when ramstage was linked using
an archive file. Because of the fact that the rmodule headers
are not referenced from any other object the link could start
by specifying the rmodule header object for ramstage. That,
however, is not the case as all ramstage objects are included
in the intermediate linked object. Therefore, the
ramstage_module_header.ramstage.o object file needs to be removed
from the object list for the ramstage rmodule.

Aaron Durbin fd79562915 romstage: add support for vboot firmware selection
This patch implements support for vboot firmware selection. The vboot
support is comprised of the following pieces:

1. vboot_loader.c - this file contains the entry point,
   vboot_verify_firmware(), for romstage to call in order to perform
   vboot selection. The loader sets up all the data for the wrapper
   to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
   API. It calls VbInit() and VbSelectFirmware() with the data supplied
   by the loader.

The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.

Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.

During ramstage there are only 2 changes:

1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
   table.
2. If a firmware selection was made in romstage the boot loader
   component is used for the payload.

Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
  components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
  contained in a signed firmware area. That's so that an errant value
  doesn't cause the size calculation to erroneously read memory it
  shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
  load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
  loader will take care of that by looking at the out flags in
VbInitParams.

Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

Aaron Durbin df3a109b72 cbmem: dynamic cbmem support
This patch adds a parallel implementation of cbmem that supports
dynamic sizing. The original implementation relied on reserving
a fixed-size block of memory for adding cbmem entries. In order to
allow for more flexibility for adding cbmem allocations the dynamic
cbmem infrastructure was developed as an alternative to the fixed block
approach. Also, the amount of memory to reserve for cbmem allocations
does not need to be known prior to the first allocation.

The dynamic cbmem code implements the same API as the existing cbmem
code except for cbmem_init() and cbmem_reinit(). The add and find
routines behave the same way. The dynamic cbmem infrastructure
uses a top down allocator that starts allocating from a board/chipset
defined function cbmem_top(). A root pointer lives just below
cbmem_top(). In turn that pointer points to the root block which
contains the entries for all the large alloctations. The corresponding
block for each large allocation falls just below the previous entry.

It should be noted that this implementation rounds all allocations
up to a 4096 byte granularity. Though a packing allocator could
be written for small allocations it was deemed OK to just fragment
the memory as there shouldn't be that many small allocations. The
result is less code with a tradeoff of some wasted memory.

           +----------------------+ <- cbmem_top()
  |   +----|   root pointer       |
  |   |    +----------------------+
  |   |    |                      |--------+
  |   +--->|   root block         |-----+  |
  |        +----------------------+     |  |
  |        |                      |     |  |
  |        |                      |     |  |
  |        |   alloc N            |<----+  |
  |        +----------------------+        |
  |        |                      |        |
  |        |                      |        |
 \|/       |   alloc N + 1        |<-------+
  v        +----------------------+

In addition to preserving the previous cbmem API, the dynamic
cbmem API allows for removing blocks from cbmem. This allows for
the boot process to allocate memory that can be discarded after
it's been used for performing more complex boot tasks in romstage.

In order to plumb this support in there were some issues to work
around regarding writing of coreboot tables. There were a few
assumptions to how cbmem was layed out which dictated some ifdef
guarding and other runtime checks so as not to incorrectly
tag the e820 and coreboot memory tables.

The example shown below is using dynamic cbmem infrastructure.
The reserved memory for cbmem is less than 512KiB.

This patch adds an option to build the ramstage as a reloctable binary.
It uses the rmodule library for the relocation. The main changes
consist of the following:

1. The ramstage is loaded just under the cmbem space.
2. Payloads cannot be loaded over where ramstage is loaded. If a payload
   is attempted to load where the relocatable ramstage resides the load
   is aborted.
3. The memory occupied by the ramstage is reserved from the OS's usage
   using the romstage_handoff structure stored in cbmem. This region is
   communicated to ramstage by an CBMEM_ID_ROMSTAGE_INFO entry in cbmem.
4. There is no need to reserve cbmem space for the OS controlled memory for
   the resume path because the ramsage region has been reserved in #3.
5. Since no memory needs to be preserved in the wake path, the loading
   and begin of execution of a elf payload is straight forward.

   distinguish a symbol that shouldn't be relocated and one that can.
   The only way to handle these symbols is to write a program to post
   process the relocations and keep a whitelist of ones that shouldn't
   be relocated. I don't believe that is a route that should be taken
   so fix the users of these sizes/limits encoded as absolute symbols
   to calculate the size at runtime or dereference a variable in memory
   containing the size/limit.

2. Absoulte symbols that were relocated to a fixed address. These
   absolute symbols are generated by assembly files to be placed at a
   fixed location. Again, these symbols are problematic because one
   can't distinguish a symbol that can't be relocated. The symbols
   are again resolved at runtime to allow for proper relocation.

For the symbols defining a size either use 2 symbols and calculate the
difference or provide a variable in memory containing the size.

David Hendricks bba8090421 armv7/exynos/snow: new cache maintenance API
This adds a new API for cache maintenance operations. The idea is
to be more explicit about operations that are going on so it's easier
to manage branch predictor, cache, and TLB cleans and invalidations.

Also, this adds some operations that were missing but required early
on, such as branch predictor invalidation. Instruction and sync
barriers were wrong earlier as well since the imported API assumed
we compield with -march=armv5 (which we don't) and was missing
wrappers for the native ARMv7 ISB/DSB/DMB instructions.

For now, this is a start and it gives us something we can easily use
in libpayload for doing things like cleaning and invalidating dcache
when doing DMA transfers.

TODO:
- Set cache policy explicitly before re-enabling. Right now it's left
  at default.
- Finish deprecating old cache maintenance API.
- We do an extra icache/dcache flush when going from bootblock to
  romstage.

Aaron Durbin f7c6d489ae rmodule: add ramstage support

static linker script. It uses these sections/symbols for locating the
drivers as well as its own program information.  Add these sections
and symbols to the rmodule linker script so that ramstage can be
linked as an rmodule. These sections and symbols are a noop for other
rmodule-linked programs, but they are vital to the ramstage.

Also add a comment in coreboot_ram.ld to mirror any changes made there
to the rmodule linker script.

Aaron Durbin 633f11274f x86: remove stack definition in linker script
In order to prepare the ramstage to be linked by the rmodule linker the
stack needs to be self-contained within the ramstage objects. The
reasoning is that the rmodule linker provides a way to define a heap,
but it doesn't currently have a region for the stack.

The downside to this is that memory footprint of the ramstage can change
when compared before this change. The size difference stems from the
link ordering of the objects as the stack is now defined within
c_start.S. The size fluctuation ranges from 0 to CONFIG_STACK_SIZE - 1
because of the previous behavior or aligning to CONFIG_STACK_SIZE. It
should be noted that such an alignment is unnecessary for 32-bit x86 as
the alignment requirement for the stacks are 4 byte alignment. Also the
memory footprint is still dominated by CONFIG_RAMTOP and CONFIG_RAMBASE.

cbfstool usage change:
   The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".

The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
  cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
  # output: 0x44, which does not look like aligned to 0x40000.

To prevent confusion, it's now switched to "-P/--page-size".

Verified by building i386/axus/tc320 (with page limitation 0x40000):
 cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
 # output: 0x44

2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.

Ronald G. Minnich 3faa2c77ed google/snow: enable GPIO entries and CHROMEOS in building
These were not separable or it would have been two CLs.

Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard.  Right now the GPIO just returns hard-wired values for
"virtual" GPIOs.

Add a chromeos.c file for snow, needed to build.

This is tested and creates gpio table entries that our hardware can use.

Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.

Ronald G. Minnich 601b27596f ARMV7: minor tweaks to inter-stage calling and payload handling.
Payloads, by design, can return. There's lots of mechanism in the payload code
to support it, and the chooser payload relies on it. Hence, we should not mark
the function call in exit_stage as noreturn.

Not all ARM have unified caches, and it's not always easy to tell what
to do. So we are very paranoid. Before we call between stages, we
should carefully flush the dcache to memory and invalidate the icache.
This may be more than is necessary on all architectures but it
doesn't really hurt for the most part.

So compile cache management code into all stages, and call the
flush dcache/invalidate icache from all stages.

The current approach only works by coincidence, so this fixes a few
things at once to get it into a working state and allow us to use
checkstack() again:

- Add a STACK_SIZE Kconfig variable. Earlier on it was evaluated to 0.

- Assign _stack and _estack using CPU-specific Kconfig variables since
  it may reside elsewhere in memory (not necessarily DRAM).

- Make the existing IRAM stack variables more useful in this context.

RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.

However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.

This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...

Patrick Georgi 315dec48ea bootblock: Reduce register load
The common part of the bootblock resets the nvram data if it's found
to be invalid. Since that code is compiled with romcc in i386 mode,
there's a shortage on registers.

Try to reduce the strain by doing things smarter: cmos_write_inner
is the same as cmos_write, just that it doesn't check if the RTC is
disabled. Since we just disabled it before, we can assume that it is so.

Hung-Te Lin f56c73f1e1 cbfstool: Use cbfs_image API for "create" command.
Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:

    "-b": base address (or offset) for bootblock. When omitted, put bootblock in
          end of ROM (x86  style).
    "-H": header offset. When omitted, put header right before bootblock,
          and update a top-aligned virtual address reference in end of ROM.

  Example: (can be found in ARM MAkefile):
    cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
             -a 64 -b 0x0000 -H 0x2040 -o 0x5000

For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".

Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.

For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

Hung-Te Lin 6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.

- Add romstage as a stage (a later patch adds it as a binary, which
  is probably wrong). The Makefile magic is complex enough that we
  let it build the XIP file for now, but we no longer use it.

- Replace findstage with loadstage. Loadstage will find a stage,
  load the code to memory, and zero the remaining part of memory.
  Now we can link the romstage to go anywhere!

- Eliminate magic offsets from code/ldscripts and centralize Kconfig
  variables in src/cpu/samsung/exynos5250/Kconfig.

- Tidy up code and serial output

Gabe Black 929f9f1719 armv7: add a wrapper for romstage's main() for ARM ISA
This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.

The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

(credit to Gabe Black for writing the patch, I'm just uploading it)

David Hendricks fba42a793a Snow bootblock (bloated/debug version)
This is the bloated Snow bootblock which includes:
- SPI driver
- UART, including requisite I2C, Maxim PMIC, and clock config code.
- Adjustments for magic offsets (id section, stack pointer address)

This is just a temporary solution until we have romstage loading.
Once that happens, we'll rip out all but the code necessary for
copying SPI ROM content into SRAM.

David Hendricks e2851f2812 make main() in snow's romstage.c our romstage entry point
Our earlier attempt was jumping straight from asm to the old u-boot
board_init_f in lowlevel_init_c.c. We are getting ready to transition
to using a real bootblock for ARM, so add romstage.c to the files
compiled and we'll make main() our entry point.

This also updates romstage.ld to place main() (*(.text.startup)) at
the beginning of romstage.

David Hendricks 0b23d47ffd armv7: Place reset vector + CBFS header + bootblock dynamically
This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.

It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.

Here is how it looks:

             0x0000 |--------------|
                    |     BL1      |
             0x2000 |--------------|
                    |    branch    |
    0x2000 + align  |--------------|
                    |  CBFS header |
0x2000 + align * 2  |--------------|
                    |   bootblock  |
                    |--------------|

TODO: The option for alignment passed into cbfstool has always been
64. Can we set it to 16 instead?

This lays out the groundwork for using a proper bootblock on ARM.
Currently we bypass the bootblock entirely and go straight to
romstage. However we want to utilize CBFS to maximize flexibility
of placing code without relying on a lot of magic numbers which
will break depending on the SoC in use.

Stefan Reinauer d37ab454d4 Implement GCC code coverage analysis
In order to provide some insight on what code is executed during
coreboot's run time and how well our test scenarios work, this
adds code coverage support to coreboot's ram stage. This should
be easily adaptable for payloads, and maybe even romstage.

See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for
more information.

To instrument coreboot, select CONFIG_COVERAGE ("Code coverage
support") in Kconfig, and recompile coreboot. coreboot will then
store its code coverage information into CBMEM, if possible.
Then, run "cbmem -CV" as root on the target system running the
instrumented coreboot binary. This will create a whole bunch of
.gcda files that contain coverage information. Tar them up, copy
them to your build system machine, and untar them. Then you can
use your favorite coverage utility (gcov, lcov, ...) to visualize
code coverage.

For a sneak peak of what will expect you, please take a look
at http://www.coreboot.org/~stepan/coreboot-coverage/

I removed the hard float support because it got errors and
coreboot should never use floats anyway. We're still having trouble
with enums but I want to see how far it gets with this patch.

Also, put the flags in a form that makes diffs easier to read. It's
almost impossible otherwise.

Finally, move some flags to the architecture Makefile, and
rely on the fact that some are set for all architectures.

Duncan Laurie 11290c49b0 SMM: Restore GNVS pointer in the resume path
The SMM GNVS pointer is normally updated only when the
ACPI tables are created, which does not happen in the
resume path.

In order to restore this pointer it needs to be available
at resume time.  The method used to locate it at creation
time cannot be used again as that magic signature is
overwritten with the address itself.  So a new CBMEM ID
is added to store the 32bit address so it can be found
again easily.

A new function is defined to save this pointer in CBMEM
which needs to be called when the ACPI tables are created
in each mainboard when write_acpi_tables() is called.

The cpu_index variable had to be renamed due to a conflict
when cpu/cpu.h is added for the smm_setup_structures()
prototype.

Gabe Black fb8632ab58 oprom: Ensure that mode information is valid before putting it in the tables.
At least when CONFIG_CHROMEOS is turned on, it's possible for
CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid
information to put into the framebuffer coreboot table. That means that what's
put in there is junk, probably all zeroes from the uninitialized global
variable the mode information is stored in (mode_info).

When a payload uses libpayload and turns on the coreboot framebuffer console,
that console will attempt to scroll at some point and decrease the cursor's y
coordinate until it is less than the number of rows claimed by the console.
The number of rows is computed by taking the vertical resolution of the
framebuffer and dividing it by the height of the font. Because the mode
information was all zeroes, the coreboot table info is all zeroes, and that
means that the number of rows the console claims is zero. You can't get the
unsigned y coordinate of the cursor to be less than zero, so libpayload gets
stuck in an infinite loop.

The solution this change implements is to add a new function,
vbe_mode_info_valid, which simply returns whether or not mode_info has anything
in it. If not, the framebuffer coreboot table is not created, and libpayload
doesn't get stuck.

sections of the binary.

To test, add "int foo;" as the first line in src/mainboard/samsung/lumpy/romstage.c
and build coreboot for Lumpy. See the build break the following
way:

    LINK       cbfs/fallback/romstage_null.debug
    Forbidden global variables in romstage:

Alexandru Gagniuc 70c660fd14 pirq_routing: Allow routing with more than 4 PIRQ links
pirq_routing_irqs assumed that only four links are available for PIRQ
routing, INTA to INTD. Some chipsets provide more, up to INTH.
When pirq_routing_irqs found a link number greater than 4 in the pirq table,
it would not assign that IRQ. This is a shame, as it limits the flexibility
of routing IRQs.
Make the maximum number of links a Kconfig variable, and modify the code to
respect it. This works beatifully on the VX900, which provides 8 routable
interrupts.
While we're at it, also refactor pirq_routing_irqs, and add some much
needed comments.
Rename pirq_routing_irqs to pirq_route_irqs to demistify the role of this
function.
The copyrights added were determined from git log filename.

Alexandru Gagniuc 00b579a447 buildsystem: Make CPU microcode updating more configurable
This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.

Choices in Kconfig
  - 1) Generate microcode from tree (default)
  - 2) Include external microcode file
  - 3) Do not put microcode in CBFS

The idea is to give the user full control over including non-free
blobs in the final ROM image.

MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:

cpu_microcode-y += microcode_file.c

MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.

These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
  1) The rule is CPU-agnostic
  2) Gives user more control over if and how to include microcode blobs
  3) The rules for building the microcode binary are kept in
   src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
   which are already overloaded and very difficult to navigate.

Stefan Reinauer 57879c9bd1 Make the device tree available in the rom stage
We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
   compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
   the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
   romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage

We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.

So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
 #ifndef __PRE_RAM__
        .ops = 0,
 #endif
        .bus = &_dev7_links[0],
        .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
        .enabled = 0,
        .on_mainboard = 1,
        .subsystem_vendor = 0x1ae0,
        .subsystem_device = 0xc000,
        .link_list = NULL,
        .sibling = &_dev22,
 #ifndef __PRE_RAM__
        .chip_ops = &southbridge_intel_bd82x6x_ops,
 #endif
        .chip_info = &southbridge_intel_bd82x6x_info_10,
        .next=&_dev22
};

in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.

Ronald G. Minnich 97de28da8a PCI Type2 config must die
PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.

Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

Ronald G. Minnich 9b4c92ad80 Fix the error message for romstage when .bss or .data are non-zero
The error message from romstage is annoying and misleading:
"Do not use global variables in romstage"

Because it can occur even when global variables are not used
in some circumstances, but also because it gives you only a rough
idea where to look. This change sucks but sucks less. We still don't
know which file the problem is in but at least we know if it is data
or bss.

Replace the error message with something that provides more information
and less guessing on the part of the script:
".bss is non-zero size in romstage which is not allowed -- global variable?"
or
".data is non-zero size in romstage which is not allowed -- global variable?"

To test: build coreboot as normal. It builds.
Add
char d[32];
to romstage.c and get the first error message; add
int x = 32;
to romstage.c and get the second.

Sven Schnelle 042c1461fb Use broadcast SIPI to startup siblings
The current code for initializing AP cpus has several shortcomings:

- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
  there's more than one physical CPU, and CPUs are of different type

Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.

Anyway, I believe at least this will cause warnings.
"resv" is a member of a union, not of acpi_addr_t. So it should be

When compiling coreboot with the latest ChromeOS toolchain, GCC

The problem is solved by using the GCC built-in __SIZE_TYPE__ if it
exists and define __SIZE_TYPE__ to long unsigned int otherwise.

zbao caf494c831 ACPI HEST table.
HEST feature starts from ACPI 4.0.

HEST is one of four kinds of tables of ACPI Platform Error
Interfaces (APEI). In Windows world, APEI is called Windows Hardware
Error Architecture (WHEA).

APEI consists of four separate tables:
1. Error Record Serialization Table (ERST)
2. BOOT Error Record Table (BERT)
3. Hardware Error Source Table (HEST)
4. Error Injection Table (EINJ)
All these 4 tables have the same header as FADT, MADT, etc. They are
pointed by RSDP.

For the HEST, it contains the error source. The types of them are
defined as
type description
1. Machine Check Exception (MCE)
2. Corrected Machine Check (CMC)
3. NMI Error
6. PCI Express Root Port AER
7. PCI Express Device AER
8. PCI Express Bridge AER
9. Generic Hardware Error Source
Error source types 3, 4, and 5 are reserved for legacy reasons and
must not be used.

Currently AMD board only provide part of "Machine Check
Exception (MCE)" & Corrected Machine Check (CMC)". we need to provide
the header of each error source. Other types of Error Sources is in
TODO list.

Only persimmon is tested. Linux can add HEST feature. The dmesg says,

ACPI: HEST 0000000066fe5010 00198 (v03 CORE COREBOOT 00000000 CORE 00000000)
......
HEST: Table parsing has been initialized.

No more message is got.

Windows can boot with this patch. Havent found a way to test it.

Existing car/cache_as_ram.inc has invalid SIPI vector and it does
not initialise AP CPU's to activate L2 cache.

Mathias Krause dd30acdd59 Fix issues with x86 memcpy
The x86 memcpy() implementation did not mention its implicit output
registers ESI, EDI and ECX which might make this code miscompile when
the compiler uses the value of EDI for the return value *after* the 'rep
movsb' has completed. That would break the API of memcpy as this would
return 'dst+len' instead of 'dst'.

Fix this possible bug by removing the wrong comment and listing all
output registers as such (using dummy stack variables that get optimized
away).

Also the leading 'cld' is superflous as the ABI mandates the direction
flag to be cleared all the time when we're in C (see
<http://gcc.gnu.org/gcc-4.3/changes.html>) and we have no ASM call sites
that might require it to be cleared explicitly (SMM might come to mind,
but it clears the DF itself before passing control to the C part of the
SMI handler).

Last but not least fix the prototype to match the one from <string.h>.

Kyösti Mälkki 7dfe32c540 Add support for RAM-less multi-processor init
For a hyper-threading processor, enabling cache requires that both the
BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram
implementation, partial multi-processor initialisation precedes
raminit and AP CPUs' 16bit entry must be run from ROM.

The AP CPU can only start execute real-mode code at a 4kB aligned
address below 1MB. The protected mode entry code for AP is identical
with the BSP code, which is already located at the top of bootblock.
This patch takes the simplest approach and aligns the bootblock
16 bit entry at highest possible 4kB boundary below 1MB.

The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR
used by the CAR code in romstage. Adress is not expected to ever
change, but if it does, link will fail.

Duncan Laurie b4aaaa7632 Prepare the BIOS data areas before device init.
Since we do not run option roms in normal mode nothing was
initializing the BDA/EBDA and yet Linux depends very much
on it having sane values here.  For the most part the kernel
tries to work around this not being initialized, but every
once in awhile (1/300 boots or so) it would end up reading
something that looked sane from BDA but was not and then
it would panic.

In this change the EBDA is unconditionally setup before devices
are initialized.  I'm not set on the location in dev_initialize()
but there does not seem to be another place to hook it in so
that it runs just once for ALL platforms regardless of whether
they use option roms or not. (possibly hardwaremain?)

The EBDA setup code has been moved into its own location in
arch/x86/lib/ebda.c so it can be compiled in even if the option
rom code is not.

The low memory size is still set to 1MB which is enough to make
linux happy without having to hook into each mainboard to get a
more appropriate value.  The setup_ebda() function takes inputs
so it could be changed for a mainboard if needed.

OLD/BROKEN would read garbage.  Examples from different boots:
ebda_addr=0x75e80 lowmem=0x1553400
ebda_addr=0x5e080 lowmem=0x3e51400
ebda_addr=0x7aa80 lowmem=0x2f8a800

NEW/FIXED now reads consistent values:
ebda_addr=0xf6000 lowmem=0x100000

Gabe Black 19e7e7d2e7 Add infrastructure for global data in the CAR phase of boot
The cbmem console structure and car global data are put in their own section,
with the cbmem console coming after the global data. These areas are linked
to be where CAR is available and at the very bottom of the stack.

There is one shortcoming of this change:
The section created by this change needs to be stripped out by the Makefile
since leaving it in confuses cbfstool when it installs the stage in the image.
I would like to make the tools link those symbols at the right location but
leave allocation of that space out of the ELF.

Patrick Georgi 3954b0ad25 Fix coreboot updates
The rule to prepare a new coreboot.pre1 was ignored in the
"update image" scenario because a perfectly fine file exists.
Mark it phony to fix it.

Patrick Georgi 914377efd6 Get rid of the old romstage-as-bootblock ROM layout
This change removes CONFIG_TINY_BOOTBLOCK, CONFIG_BIG_BOOTBLOCK, and
all their uses, assuming TINY_BOOTBLOCK=y, BIG_BOOTBLOCK=n.

This might break a couple of boards on runtime, but so far, fixes were
quite simple.
There's a flag day: Code that relies on CONFIG_TINY_BOOTBLOCK must be
adapted.

Patrick Georgi 1da104647d Get rid of AUTO_XIP_ROM_BASE
That value is now generated from a code address and CONFIG_XIP_ROM_SIZE.
This works as MTRRs are fully specified by their size and any address
within the range.

Patrick Georgi 07b4215e11 Move linux 2.6.11 workaround to generic code
Linux 2.6.11 seems to require a certain order in CPUs listed in mptable,
so enforce it. This was only done on arima/hdama, but now is generic.
Unfortunately this is somewhat slow.
