Add 4 helper functions to get microcode info.
* get_current_microcode_rev
return the the version of the currently running microcode.
* get_microcode_rev
extract microcode revision from the given patch.
* get_microcode_size
extract microcode size from the given patch.
* get_microcode_checksum
extract checksum from the given patch.
The simpler thing would be to just move the struct microcode
to microcode.h so that the structure members can be dereferenced.
To encapsulate the structure details added the helper functions.
This information will be used in future to compare microcodes for update.

Hardcoding the microcode filenames into the makefiles is great when
the microcode is in the blobs directory. When the microcode isn't
posted to the blobs directory, we need some method of supplying the
microcode binary into the build. This can of course be done manually
after the build has completed, as can be done with everything that
we're including in the ROM image. Instead of making life hard for
everyone though, let's just add a way to specify where the microcode
rom comes from.

The previous usage of the intel microcode support supported using
the library under ROMCC and ramstage. Allow for microcode support
to be used in normal C-based romstage as well by:
1. Only using walkcbfs when ROMCC is defined.
2. Only using spinlocks if !__PRE_RAM__
The header file now unconditionally exposes the declarations
of the supporting functions.

A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.
All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.
The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The sequence to inject microcode updates is virtually the same for all
Intel CPUs. The same function is used to inject the update in both CBFS
and hardcoded cases, and in both of these cases, the microcode resides in
the ROM. This should be a safe change across the board.
The function which loaded compiled-in microcode is also removed here in
order to prevent it from being used in the future.
The dummy terminators from microcode need to be removed if this change is
to work when generating microcode from several microcode_blob.c files, as
is the case for older socketed CPUs. Removal of dummy terminators is done
in a subsequent patch.

SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from

Add a safety check in function `intel_update_microcode` to return when
accidentally `NULL` is passed as `microcode_updates`, which would lead
to a null pointer dereference later on.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
While at it, use `return NULL` for clarity in function
`intel_microcode_find` and include the header file `stddef.h`. for it.
The review of this patch had some more discussion on adding more
comments and more detailed error messages. But this should be done in
a separate patch.
For clarity here some history, on how this was found and what caused
the discussion and confusion.
Originally when Vladimir made this improvement, selecting
`CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob
`cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference
later on causing a crash.
for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {
Vladimir fixed this by returning if `microcode_updates` is `NULL`,
that means no file is found and successfully tested this on his
Lenovo X201.
When pushing the patch to Gerrit for review, the code was rewritten
though by Aaron in commit »intel microcode: split up microcode loading
stages« (98ffb426) [1], which also returns when no file is found. So
the other parts of the code were checked and the safety check as
described above is added.

This patch only applies to CONFIG_MICROCODE_IN_CBFS. The intel microcode
update routine would always walk the CBFS for the microcode file. Then
it would loop through the whole file looking for a match then load the
microcode. This process was maintained for intel_update_microcode_from_cbfs(),
however 2 new functions were exported:
1. const void *intel_microcode_find(void)
2. void intel_microcode_load_unlocked(const void *microcode_patch)
The first locates a matching microcode while the second loads that
mircocode. These new functions can then be used to cache the found
microcode blob w/o having to re-walk the CBFS.
Booted baskingridge board to Linux and noted that all microcode

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 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.

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.

Another bug in the Intel microcode update code that existed since we switched
to LinuxBIOSv2 in 2004:
The inline assembly code that reads the CPU revision from an MSR after running
cpuid(1) trashes registers EBX and ECX. Only ECX was mentioned in the clobber
list. C code running after this function could silently access completely wrong
data, which resulted in the wrong date being printed on microcode updates (and
potentially other issues happening until the C code writes to EBX again)

- add GPLv2 + copyright header after talking to Ron
- "bits" in struct microcode served no real purpose but
getting its address taken. Hence drop it
- use asm volatile instead of __asm__ volatile
- drop superfluous wrmsr (that seems to be harmless but
is still wrong) in read_microcode_rev
- use u32 instead of unsigned int where appropriate
- make code usable both in bootblock and in ramstage
- drop ROMCC style print_debug statements
- drop microcode update copy in Sandybridge bootblock

This also has an additional benefit:
I was running "sh update-microcodes.sh" previously which broke with
update-microcodes.sh: 102: Bad substitution
due to the script requiring /bin/bash instead of /bin/sh (uses bash-specific
stuff). Running "bash update-microcodes.sh" works fine.
Making the script executable in svn reduces the likelyhood of people
running the script with differing shells that may not work.

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.

This still requires someone to adjust the #includes in the
model_XXX_init.c files but with a script we're getting closer
to automate the update of 3rd party files.

while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)

Only some assembler files still have \r\n ... Can we move that part to C
completely?
