Kyösti Mälkki 4d409b5fc2 usbdebug: Refactor disable logic
Output to usbdebug console needs to be disabled until hardware is
initialized and while EHCI BAR is relocated. Add separate field
ehci_info to point to back to EHCI context when hardware is ready
to transfer data.

Ronald G. Minnich 78c3e33550 FUI: reorganize include files
We've got enough of a handle on this to realize some things:
drm_dp_helper.h is by design device and architecture independent
i915.h is common to most intel graphics chipsets going back several years
i915_reg.h is as well

Move these files to src/include/device, and adjust the .c files accordingly.

Ronald G. Minnich b2893a0169 Provide support for setting up the framebuffer from EDID
Add three functions to edid.c:

void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
as well as setting the static vbe_valid to 1 unless some problem
is found in the edid. The intent here is that this could be called from
the native graphics setup code on both ARM and x86.

int vbe_mode_info_valid(void)
returns value of the static vbe_valid.

void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.

There is now a common vbe.h in src/include, removed the two special ones.

In general, graphics in coreboot is a mess, but graphics is always a
mess.  We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.

The best part: this code would also work for ARM, which also uses EDID.

In some cases, we want a ram_check that does not die and does not
clobber the terminal with useless output that slows us down a lot.
Usage examples include Checking if the RAM is up at the start of
raminit, or checking if each rank is accessible as it is being
initialized.

As with all other ram_checks, this is more of a "Is my DRAM properly
configured?" test, which is exactly what we want for something to use
during memory initialization.

Aaron Durbin 2ad6bd23a7 cbmem console: use cache-as-ram API and cleanup
Allow for automatic cache-as-ram migration for the cbmem
console. The code was refactored in the thought of making
it easier to read. The #ifdefs still exist, but they are no
longer sprinkled throughout the code. The cbmem_console_p
variable now exists globally in both romstage and ramstage.
However, the cbmem_console_p is referenced using the
cache-as-ram API. When cbmem is initialized the console
is automatically copied over by calling cbmemc_reinit()
through a callback.

Aaron Durbin 716738a6b8 x86: add cache-as-ram migration option
There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage
is loaded. For example, using vboot to verify the ramstage
is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.

Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.

Aaron Durbin 4409a5eef6 coreboot: add thread cooperative multitasking
The cooperative multitasking support allows the boot state machine
to be ran cooperatively with other threads of work. The main thread
still continues to run the boot state machine
(src/lib/hardwaremain.c).  All callbacks from the state machine are
still ran synchronously from within the main thread's context.
Without any other code added the only change to the boot sequence
when cooperative multitasking is enabled is the queueing of an idlle
thread. The idle thread is responsible for ensuring progress is made
by calling timer callbacks.

The main thread can yield to any other threads in the system. That
means that anyone that spins up a thread must ensure no shared
resources are used from 2 or more execution contexts. The support
is originally intentioned to allow for long work itesm with busy
loops to occur in parallel during a boot.

Note that the intention on when to yield a thread will be on
calls to udelay().

Aaron Durbin 0748d30554 boot state: add ability to block state transitions
In order to properly sequence the boot state machine it's
important that outside code can block the transition from
one state to the next. When timers are not involved there's
no reason for any of the existing code to block a state
transition. However, if there is a timer callback that needs to
complete by a certain point in the boot sequence it is necessary
to place a block for the given state.

To that end, 4 new functions are added to provide the API for
blocking a state.
1. boot_state_block(boot_state_t state, boot_state_sequence_t seq);
2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq);
3. boot_state_current_block(void);
4. boot_state_current_unblock(void);

entry into a state but before its entry callbacks. In addition

	BS_WRITE_TABLES
	BS_PAYLOAD_LOAD
	BS_PAYLOAD_BOOT

Future functionality consists of evaluating the timer callbacks within
the device tree. One example is dev_initialize() as that seems state
seems to take 90% of the boot time. The timer callbacks could then be
ran in a more granular manner.

In order to be more flexible the concept of a boot state machine
is introduced. At the boundaries (entry and exit) of each state there
is opportunity to run callbacks. This ability allows one to schedule
actions to be performed without adding board-specific code to
the shared boot flow.

Aaron Durbin e1be5ae2f4 rmodule: put all code/data bits in one section
While debugging a crash it was discovered that ld was inserting
address space for sections that were empty depending on section
address boundaries. This led to the assumption breaking down that
on-disk payload (code/data bits) was contiguous with the address
space. When that assumption breaks down relocation updates change
the wrong memory. Fix this by making the rmodule.ld linker script
put all code/data bits into a payload section.

Stefan Reinauer 642b1db733 Eliminate use of pointers in coreboot table
Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.

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.

Aaron Durbin 159f2ef03a ramstage: cache relocated ramstage in RAM
Accessing the flash part where the ramstage resides can be slow
when loading it. In order to save time in the S3 resume path a copy
of the relocated ramstage is saved just below the location the ramstage
was loaded. Then on S3 resume the cached version of the relocated
ramstage is copied back to the loaded address.

This is achieved by saving the ramstage entry point in the
romstage_handoff structure as reserving double the amount of memory
required for ramstage. This approach saves the engineering time to make
the ramstage reentrant.

The fast path in this change will only be taken when the chipset's
romstage code properly initializes the s3_resume field in the
romstage_handoff structure. If that is never set up properly then the
fast path will never be taken.

e820 entries from Linux:
BIOS-e820: [mem 0x000000007bf21000-0x000000007bfbafff] reserved
BIOS-e820: [mem 0x000000007bfbb000-0x000000007bffffff] type 16

The type 16 is the cbmem table and the reserved section contains the two
copies of the ramstage; one has been executed already and one is
the cached relocated program.

With this change the S3 resume path on the basking ridge CRB shows
to be ~200ms to hand off to the kernel:

13 entries total:

   1:95,965
   2:97,191 (1,225)

Aaron Durbin 8e4a355773 coreboot: introduce CONFIG_RELOCATABLE_RAMSTAGE
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.

Aaron Durbin ad93552b86 lib: add rmodule support
A rmodule is short for relocation module. Relocaiton modules are
standalone programs. These programs are linked at address 0 as a shared
object with a special linker script that maintains the relocation
entries for the object. These modules can then be embedded as a raw
binary (objcopy -O binary) to be loaded at any location desired.

Initially, the only arch support is for x86. All comments below apply to
x86 specific properties.

The intial user of this support would be for SMM handlers since those
handlers sometimes need to be located at a dynamic address (e.g. TSEG
region).

The relocation entries are currently Elf32_Rel. They are 8 bytes large,
and the entries are not necessarily in sorted order. An future
optimization would be to have a tool convert the unsorted relocations
into just sorted offsets. This would reduce the size of the blob
produced after being processed. Essentialy, 8 bytes per relocation meta
entry would reduce to 4 bytes.

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.

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/

reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged

The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c

Ronald G. Minnich 9764d4c690 Implement stack overflow checking for the BSP
Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.

Break the stack checking out into a separate function, which
we will later use for the APs.

CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000

Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

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.

Vadim Bendebury 32da8bed19 CBMEM CONSOLE: Add CBMEM console driver implementation.
The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.

There are some system limitations which need to be worked around
to achieve this goal:

- some console traffic is generated before DRAM is initialized,
  leave alone CBMEM initialized.

- after the RAM based stage starts, a lot of traffic is generated
  before CBMEM is initialized.

As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.

When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.

At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.

When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.

In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

Vadim Bendebury 6f72d6965c Add timestamp collecting to coreboot.
This patch adds code to initialize the time stamp collection
facility in coreboot. It adds a table in the CBMEM section, which
provides the base timer reading value (all other readings are
offsets of this one) and an array of timestamp id/timestamp value
pairs.

Just two values are being added now, this will have to be used
more extensively and also integrated into payloads to provide more
comprehensive boot process time measurements.

Also, since the CBMEM area could already contain a section (from the
previous run, before reset), when processing a section addition
request we should check if a section already exists and return its
address, if so.

Vadim Bendebury e1860604e4 Initialize CBMEM early.
We want to be able to share data between different phases of firmware
(rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate
location for this data, but normally it is not initialized
until coreboot reaches the ram stage.

This change initializes the CBMEM while still in rom stage in
case CONFIG_EARLY_CBMEM_INIT is set.

Note that there is a discrepancy in how coreboot determines the
size of DRAM at rom and ram stages, get_top_of_ram() is used at
rom stage and is not defined for all platforms. Those platforms
will have to define this function should they enable the
CONFIG_EARLY_CBMEM_INIT flag.

Build fix for src/arch/i386/boot/acpi.c if !CONFIG_SMP
Also check for acpi_slp_type 2 in acpi_is_wakeup, since S2
uses the same acpi wakeup vector as S3.
Add _PTS/_WAK methods to turn off/on the CPU/case fans and blink
the power LED while sleeping.
acpi_get_sleep_type() is in a seperate file i82371eb_wakeup.c because
it is used in both romstage and ramstage after patch 3/3, whereas
i82371eb_early_pm.c is used only in romstage.
I used the name acpi_get_sleep_type instead of  acpi_is_wakeup_early
because I think acpi_is_wakeup_early is a bit misleading as a name since it
doesn't return a boolean value.

Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the
added check for acpi_slp_type == 2 (resume from S2) should not
change behaviour of other boards:

Rudolf Marek bcaea142f3 1) wraps the s3 parts of chipset code/memory init code with if CONFIG_HAVE_ACPI_RESUME == 1 getting rid of ugly define in romstage.c
2) the patch implements get_cbmem_toc in chipset specific way if defined.
On Intel targets it should be unchanged. On K8T890 the the cbmem_toc is read from NVRAM. Why you ask? Because we cannot do it as on intel, because the framebuffer might be there making it hard to look for it in memory (and remember we need it so early that everying is uncached)

3) The patch removes hardcoded limits for suspend/resume save area (it was 1MB) on intel. Now it computes right numbers itself.

4) it impelements saving the memory during CAR to reserved range in sane way. First the sysinfo area (CAR data) is copied, then the rest after car is disabled (cached copy is used). I changed bit also the the copy of CAR area is now done uncached for target which I feel is more right.

I think I did not change the Intel suspend/resume behaviour but best would be if someone can test it. Please note this patch was unfinished on my drive since ages and it would be very nice to get it in to prevent bit rotten it again.
Now I feel it is done good way and should not break anything. I did a test with abuild and it seems fine.

- Hook up malloc() debug code via CONFIG_DEBUG_MALLOC. Only show it in
   menuconfig if at least DEBUG or SPEW are selected as loglevel, as this
   code does additional printk(BIOS_DEBUG, ...) calls which would otherwise
   not be visible anyway.

 - Similarly, make DEBUG_CAR and REALMODE_DEBUG only visible if thr DEBUG or
   SPEW loglevel is selected.

 - Get rid of a custom "debug" macro, use printk() as usual.

Patrick Georgi 8463dd9db0 Rename build system variables to be more intuitive, and
at the same time let the user specify sources instead
of object files:
- objs becomes ramstage-srcs
- initobjs becomes romstage-srcs
- driver becomes driver-srcs
- smmobj becomes smm-srcs

The user servicable parts are named accordingly:
ramstage-y, romstage-y, driver-y, smm-y

Also, the object file names are properly renamed now, using
.ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.

Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't
easily fit in the build system and aren't useful anyway.

Stefan Reinauer 6bee951c30 dependency tracking for coreboot
Obviously compile time increases slightly because more work has to be done, but
I'm sure the benefit of having to rm -rf build less often is worth it :-)

Other small changes:
* be a bit more verbose on some of the created files
* move -O2 from compiler rule into bootblock_romccflags
* drop rule needed for util/*.c -> build/*.o as x86emu no longer lives in util.

Stefan Reinauer 9fe4d797a3 coreboot used to have two different "APIs" for memory accesses:
read32(unsigned long addr) vs readl(void *addr)
and
write32(unsigned long addr, uint32_t value) vs writel(uint32_t value, void *addr)

read32 was only available in __PRE_RAM__ stage, while readl was used in stage2.
Some unclean implementations then made readl available to __PRE_RAM__ too which
results in really messy includes and code.

This patch fixes all code to use the read32/write32 variant, so that we can
remove readl/writel in another patch.

Patrick Georgi b203c2f95e 20090819-2-trim-down-cbfs:
CBFS uses sprintf, which requires vtxprintf, which requires (in the
current design) a nested function. That works on x86, but on PPC this
requires a trampoline. In the ROM stage, this is not available, so
remove the single use of sprintf and replace it with a direct string
handler - it's only used to fill in fixed-length hex values.

Ronald G. minnich d41de2ea7a These changes implement car in qemu. The implementation is in several
ways superior to v3, while lacking its completeness. But, one nice 
thing: no more included .S or .c files. It's all separate compilation. 
That should allow our Makefiles to work much better.

Note that the current non-CAR implementation is the default and 
continues to work (tested FILO boot to Linux on both CAR and non-CAR).

Index: src/mainboard/emulation/qemu-x86/Config.lb
Change this to be sensitive to USE_DCACHE_RAM. All settings etc. that 
depend on this variable are grouped in one if, and the other parts

Patrick Georgi 195f5cd666 Add lzma.o for CBFS, regardless if CONFIG_COMPRESSED_PAYLOAD_LZMA is
enabled or not.
CONFIG_COMPRESSED_PAYLOAD_LZMA is set only if the lzma utility is found
on the system - at least when using abuild. CBFS doesn't use this tool
for compression.

The result was a failed build if lzma (the tool) wasn't found, or
failed runtime (if src/lib/cbfs.c disables lzma decompression based on
CONFIG_COMPRESSED_PAYLOAD_LZMA)

Myles Watson fa12b67771 Remove warnings from compilation of the s2892 with and without CBFS.
I didn't try to remove "defined but not used" warnings because there are too
many ifdefs to be sure I wouldn't break something.

For shadowed variable declarations I renamed the inner-most variable.  

The one in src/pc80/keyboard.c might need help.  I didn't change the
functionality but it looks like a bug.

Patrick Georgi 12aba82e55 Refactor copy_and_run so that it uses a single code base instead of
3 (with one of them way too much assembler code).

On the way, I had to make some changes to the way the code is built, 
which is an effort I want to expand over time.
Right now, large portions of the in-ROM part of coreboot is compiled as 
a single file, with lots of .c files including other .c files.
That has its justification for pre-raminit code, but it also affects 
lots of post-raminit code (memcpy doesn't really make sense before 
raminit, or at least CAR)

The coreboot_apc code (AMD boards) gained some .c includes because I 
don't know that part of the code enough to really rework it and only 
have limited possibilities to test it. The includes should give an 
identical situation for this part of the code.

This change was posted as set of 6 patches to the list, but they
were mostly split for review purposes, hence commit them all at once.
They can still be backed up using the patch files, if necessary.

Patrick Georgi dcce5210c7 Make the CBFS file lookup skip file data instead of brute-forcing
its way through it, looking for magic numbers.
For one, it should speed up file access, esp. with many entries,
but it also helps against false positives (eg. seabios, which
contains the magic number for its own CBFS support, which _might_
just be aligned properly)

Also avoid infinite loops and give up searching for new files for
invalid magic numbers.

Patrick Georgi 7994164a0e Remove the inclusion of lzma.c (which really contains code)
from another (rom_stream.c and others), instead linking it like any
source file should be linked.

The same should (and will) be done with nrv2b.c, but that has some
deeper implications as various CAR implementations include that
directly, and thus requires more care.

It fixes an issue with the cbfs code.

Ronald G. Minnich b3b7db777d This fixes a bug in romfs code; see comment. If we add the pci rom
to romfs for qemu,we get this: 
Check pci1013,00b8.rom
found it, @ fff99698, first word is e946aa55
In cbfs, rom address for PCI: 00:02.0 = 0
On mainboard, rom address for PCI: 00:02.0 = fff99698
copying VGA ROM Image from fff99698 to 0xc0000, 0x8c00 bytes

This is sort of OK, excpet that when it gets to payload time, the 
system explodes. I suspect that copy is kind of a problem. 

But this is a pretty important bug fix so in it goes.

Ronald G. Minnich d7a709a60f These are some cleanups and changes. These are build and boot tested on qemu.
Some changes for option roms: 
- don't make users pick the name. Names for option roms are in the v3-defined
format of pci%04x,%04x.rom with the vendor and device id filling in the 
%04x. 
- users pass in vendor and device id. 
- users pass in a dest. If the dest is 0, the address of the ROM image in 
FLASH is returned. If the address is non-zero, then the decmpressor is called,
and it will make sure the ROM image is copied to the destination (even 
in the uncompressed case).

And some type and print cleanup.

Ward Vandewege ec2bd53c37 If you have
option CONFIG_COMPRESSED_PAYLOAD_LZMA=1
  option CONFIG_PRECOMPRESSED_PAYLOAD=1

set in Config.lb but accidentally use an uncompressed payload, coreboot (v2)
bombs out like this:

  elfboot: Attempting to load payload.
  rom_stream: 0xfffc0000 - 0xfffdefff
  Uncompressing to RAM 0x01000000 Decoder scratchpad too small!
  Decoding error = 1
  Unexpected Exception: 6 @ 10:04000408 - Halting
  Code: 0 eflags: 00010057
  eax: 00000101 ebx: 04000400 ecx: 000003d4 edx: fffc0000
  edi: 04000400 esi: 04000401 ebp: 04000400 esp: 0013dfb4

The attached patch modifies v2's lzma code so that it assumes an uncompressed
payload if it fails to find a properly compressed payload.

Compare with the fatal error above:

  elfboot: Attempting to load payload.
  rom_stream: 0xfffc0000 - 0xfffdefff
  Uncompressing to RAM 0x01000000 Decoder scratchpad too small!
   olen = 0x00000000 done.
  Decompression failed. Assuming payload is uncompressed...
  Found ELF candidate at offset 0
  header_offset is 0
  Try to load at offset 0x0

If you don't have CONFIG_COMPRESSED_PAYLOAD_LZMA and
CONFIG_PRECOMPRESSED_PAYLOAD set and use an uncompressed payload, things are as
before:

  elfboot: Attempting to load payload.
  rom_stream: 0xfffc0000 - 0xfffdefff
  Found ELF candidate at offset 0
  header_offset is 0
  Try to load at offset 0x0

One can argue that this is a case of 'builder beware', but my counter argument
is that anything that causes unexpected runtime breakage is really, really,
really bad, and should be avoided where possible.

This patch also fixes one erroneous comment.

Eric Biederman 69afe2822a mpspec.h: Tweak the write_smp_table macro so that it is safe if passed a complex expression.
crt0.S.lb: Modified so that it is safe to include console.inc
console.c:  Added print_debug_ and frieds which are non inline variants of the normal console functions
div64.h:   Only include limits.h if  ULONG_MAX is not defined and define ULONG_MAX on ppc
socket_754/Config.lb Conditionally set config chip.h
socket_940.c We don't need and #if CONFIG_CHIP_NAME we won't be linked in if there are no references.
slot_2/chip.h: The operations struct need to be spelled cpu_intelt_slot_2_ops
slot_2/slot2.c: The same spelling fix
socket_mPGA603/chip.h: again
socket_mPGA603/socket_mPGA603_400Mhz.c: and again
socket_mPGA604_533Mhz/Config.lb: Conditionally defing CONFIG_CHIP_NAME
socket_mPGA604_800Mhz/chip.h: Another spelling fix
socket_mPGA604_800Mhz.c     and again
via/model_centaur/model_centaur_init.c: It's not an intel CPU so don't worry about Intel microcode uptdates
earlymtrr.c:  Remove work around for older versions of romcc
pci_ids.h:  More ids.
malloc.c:   We don't need string.h any longer
uart8250.c: Be consistent when delcaring functions static inline
arima/hdama/mptable.c: Cleanup to be a little more consistent
amdk8/coherent_ht.c:
 - Talk about nodes not cpus (In preparation for dual cores)
 - Remove clear_temp_row (as it is no longer needed)
 - Demoted the failure messages to spew.
 - Modified to gracefully handle failure (It should work now if cpus are removed)
 - Handle the non-SMP case in verify_mp_capabilities
 - Add clear_dead_routes which replaces clear_temp_row and does more
 - Reorganize setup_coherent_ht_domain to cleanly handle failure.
 - incoherent_ht.c: Clean up the indenation a little.
i8259.c: remove blank lines at the start of the file.
keyboard.c: Make pc_keyboard_init static
ramtest.c: Add a print out limiter, and cleanup the printout a little.
amd8111/Config.lb: Mention amd8111_smbus.c
amd8111_usb.c: Call the structure usb_ops not smbus_ops.
NSC/pc97307/chip.h: Fix spelling issue
pc97307/superio.c: Use &ops no &pnp_ops.
w83627hf/suerio.c: ditto
w83627thf/suerio.c: ditto
buildrom.c: Use braces around the body of a for loop.  It's more maintainable.

Eric Biederman 5cd81730ec - Moved hlt() to it's own header.
- Reworked pnp superio device support.  Now complete superio support is less than 100 lines.
- Added support for hard coding resource assignments in Config.lb
- Minor bug fixes to romcc
- Initial support for catching the x86 processor BIST error codes.  I've only seen
  this trigger once in production during a very suspcious reset but...
- added raminit_test to test the code paths in raminit.c for the Opteron
- Removed the IORESOURCE_SET bit and added IORESOURCE_ASSIGNED and IORESOURCE_STORED
  so we can tell what we have really done.
- Added generic AGP/IOMMU setting code to x86
- Added an implementation of memmove and removed reserved identifiers from memcpy
- Added minimal support for booting on pre b3 stepping K8 cores
- Moved the checksum on amd8111 boards because our default location was on top of
  extended RTC registers
- On the Hdama added support for enabling i2c hub so we can get at the temperature
  sensors.  Not that i2c bus was implemented well enough to make that useful.
- Redid the Opteron port so we should only need one reset and most of memory initialization
  is done in cpu_fixup.  This is much, much faster.
- Attempted to make the VGA IO region assigment work.  The code seems to work now...
- Redid the error handling in amdk8/raminit.c to distinguish between a bad value
  and a smbus error, and moved memory clearing out to cpufixup.
- Removed CONFIG_KEYBOARD as it was useless.  See pc87360/superio.c for how to
  setup a legacy keyboard properly.
- Reworked the register values for standard hardware, moving the defintions from
  chip.h into the headers of the initialization routines.  This is much saner
  and is actually implemented.
- Made the hdama port an under clockers BIOS.  I debuged so many interesting problems.
- On amd8111_lpc added setup of architectural/legacy hardware
- Enabled PCI error reporting as much as possible.
- Enhanded build_opt_tbl to generate a header of the cmos option locations so
  that romcc compiled code can query the cmos options.
- In romcc gracefully handle function names that degenerate into function pointers
- Bumped the version to 1.1.6 as we are getting closer to 2.0

  TODO finish optimizing the HT links of non dual boards
  TODO make all Opteron board work again
  TODO convert all superio devices to use the new helpers
  TODO convert the via/epia to freebios2 conventions
  TODO cpu fixup/setup by cpu type
