"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.)

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.

This patch does a few things to get us into romstage:
- 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

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)

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.

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.

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?

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/

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

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.

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.

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.

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 = {

.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},

When microcode storage in CBFS is enabled, the make system is supposed
to generate the microcode blob and place it into the generated ROM
image as a CBFS component.
The microcode source representation does not change: it is still an
array of 32 bit constants. This new addition compiles the array into a
separate object file and then strips all sections but data.
The raw data section is then included into CBFS as a file named
'microcode_blob.bin' of type 0x53, which is assigned to microcode
storage.

Code can easily make the mistake of using uninitialized

when an address is desired.
Set the stack to a non-zero value which is also (by testing)
a pointer which will crash coreboot if used. This poisoning
has uncovered at least one bug.

This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.
Syntax in devicetree.cb:
ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>
The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

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.

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.

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.

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)

The socket mPGA604 is for P4 Xeon which to my knowledge is always
HT-enabled. I assume the existing usage of car/cache_as_ram.inc
on socket_mPGA604, namely the Tyan S2735, as broken.
Existing car/cache_as_ram.inc has invalid SIPI vector and it does
not initialise AP CPU's to activate L2 cache.
Other mPGA604 boards are not affected, as they have not been
converted to CAR.

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>.

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.

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

It looks like the cbfstool utility generates the output file even when
it fails to generate it properly. This causes make, if started second
time in a row, after cbfstool failure, to continue beyond the point of
failure (as the corrupted output file is present in the output tree,
the second make invocation presumes that it is valid, as it is newer
than the dependencies).
The output file should be created only when successful, in an atomic
operation. There could be other places in the make system which
require a similar fix, this needs to be investigated further.
