Certain MMIO resources can be set to a write-combining cacheable

The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes
on a resource provided hints to the MTRR algorithm. The
IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable
space for the resource. The IORESOURCE_IGNORE_MTRR directed
the MTRR algorithm to ignore this resource as it was used reserving
RAM space.
Now that the optimizing MTRR algorithm is in place there isn't a need
for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the
MTRR code merging resources of the same cacheable type. The users
of the IORESOURCE_UMA_FB will find that the default MTRR type
calculation means there isn't a need for this flag any more.

The old MTRR code had issues using too many variable
MTRRs depending on the physical address space layout dictated
by the device resources. This new implementation calculates
the default MTRR type by comparing the number of variable MTRRs
used for each type. This avoids the need for IORESOURE_UMA_FB
because in many of those situations setting the default type to WB
frees up the variable MTTRs to set that space to UC.
Additionally, it removes the need for IORESOURCE_IGNORE_MTRR
becuase the new mtrr uses the memrange library which does merging
of resources.
Lastly, the sandybridge gma has its speedup optimization removed
for the graphics memory by writing a pre-determined MTRR index.
That will be fixed in an upcoming patch once write-combining support
is added to the resources.
Slight differences from previous MTRR code:
- The number of reserved OS MTRRs is not a hard limit. It's now advisory
as PAT can be used by the OS to setup the regions to the caching
policy desired.
- The memory types are calculated once by the first CPU to run the code.
After that all other CPUs use that value.
- CONFIG_CACHE_ROM support was dropped. It will be added back in its own
change.
A pathological case that was previously fixed by changing vendor code
to adjust the IO hole location looked like the following:
MTRR: Physical address space:
0x0000000000000000 - 0x00000000000a0000 size 0x000a0000 type 6
0x00000000000a0000 - 0x00000000000c0000 size 0x00020000 type 0
0x00000000000c0000 - 0x00000000ad800000 size 0xad740000 type 6
0x00000000ad800000 - 0x00000000d0000000 size 0x22800000 type 0
0x00000000d0000000 - 0x00000000e0000000 size 0x10000000 type 1
0x00000000e0000000 - 0x0000000100000000 size 0x20000000 type 0
0x0000000100000000 - 0x000000014f600000 size 0x4f600000 type 6
As noted by the output below it's impossible to accomodate those
ranges even with 10 variable MTRRS. However, because the code
can select WB as the default MTRR type it can be done in 6 MTRRs:
MTRR: default type WB/UC MTRR counts: 6/14.
MTRR: WB selected as default type.
MTRR: 0 base 0x00000000ad800000 mask 0x0000007fff800000 type 0

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 + 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.

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

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.

There is a need to calculate the proper placement for an rmodule
in memory. e.g. loading a compressed rmodule from flash into ram
can be an issue. Determining the placement is hard since the header
is not readable until it is decompressed so choosing the wrong location
may require a memmove() after decompression. This patch provides
a function to perform this calculation by finding region below a given
address while making an assumption on the size of the rmodule header..

This code is taken from an EDID reader written at Red Hat.
The key function is
int decode_edid(unsigned char *edid, int size, struct edid *out)
Which takes a pointer to an EDID blob, and a size, and decodes it into
a machine-independent format in out, which may be used for driving
chipsets. The EDID blob might come for IO, or a compiled-in EDID
BLOB, or CBFS.
Also included are the changes needed to use the EDID code on Link.

There is a plan to utlize rmodules for loading ramstage as a
relocatable module. However, the rmodule header may change.
In order to provide some wiggle room for changing the contents
of the rmodule header add some padding. This won't stop the need
for coordinating properly between the romstage loader that may be
in readonly flash and rmodule header fields. But it will provide
for a way to make certain assumptions about alignment of the
rmodule's program when the rmodule is compressed in the flash.

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.

Add support for SMM modules by leveraging the RMODULE lib. This allows
for easier dynamic SMM handler placement. The SMM module support
consists of a common stub which puts the executing CPU into protected
mode and calls into a pre-defined handler. This stub can then be used
for SMM relocation as well as the real SMM handler. For the relocation
one can call back into coreboot ramstage code to perform relocation in
C code.
The handler is essentially a copy of smihandler.c, but it drops the TSEG
differences. It also doesn't rely on the SMM revision as the cpu code
should know what processor it is supported.
Ideally the CONFIG_SMM_TSEG option could be removed once the existing
users of that option transitioned away from tseg_relocate() and
smi_get_tseg_base().
The generic SMI callbacks are now not marked as weak in the
declaration so that there aren't unlinked references. The handler
has default implementations of the generic SMI callbacks which are
marked as weak. If an external compilation module has a strong symbol
the linker will use that instead of the link one.
Additionally, the parameters to the generic callbacks are dropped as
they don't seem to be used directly. The SMM runtime can provide the
necessary support if needed.

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.

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/

This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.
This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.
The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.
uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

The SB800 and Hudson now support adding the IMC ROM which runs from the same
chip as coreboot. When the IMC is running, write or erase commands sent to
the spi bus will fail, and the IMC will die. To fix this, we send a request
to the IMC to stop fetching from the SPI rom while we write to it. This
process (in one form or another) is required for writes to the SPI bus while
the IMC is running.
Because the IMC can take up to 500ms to respond every time we claim the
bus, this patch tries to keep the number of times we need to do that to a
minimum. We only need to claim the bus on writes, and using a counter for
the semaphore allows us to call in once to claim the bus at the beginning
of a number of transactions and it will stay claimed until we release it
at the end of the transactions.
Claim() - takes up to 500ms hit
claim() - no delay
erase()
release()
claim() - no delay

time cannot be used again as that magic signature is

A new function is defined to save this pointer in CBMEM

in each mainboard when write_acpi_tables() is called.
The cpu_index variable had to be renamed due to a conflict

If the event log is stored in flash that is not memory

the flash device instead of relying on memory accesses.
In addition a new CBMEM ID is added to keep an resident
copy of the ELOG around if needed. The use of CBMEM for
this is guarded by a new CONFIG_ELOG_CBMEM config option.
This CBMEM buffer is created and filled late in the process
when the SMBIOS table is being created because CBMEM is
not functional when ELOG is first initialized.
The downside to using CBMEM is that events added via the
SMI handler at runtime are not reflected in the CBMEM copy
because I don't want to let the SMM handler write to memory
outside the TSEG region.
In reality the only time we add runtime events is at kernel
shutdown so the impact is limited.

log is operational and SMBIOS points to address in CBMEM.
The test should involve at least on reboot to ensure that the

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.

Unfortunately the method of synchronizing rdtsc is different

Hence, use the correct lfence/mfence instructions (for CPUs that

Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.
If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:
void mainboard_post(u8 value)
{
switch(value){
case POST_TIME_TO_PARTY: some_fancy_lights();
break;
}
}
Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

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
};

The linux kernel contains an SMI driver that was written by
me (Duncan) and upstreamed a couple years ago called GSMI.
This driver will format a parameter buffer and pass pointers
to this parameter buffer to the SMI handler. It uses this to
generate events for kernel shutdown reasons: Clean, Panic, Oops,
etc.
This function expects to be passed pointers into the SMM state
save area that correspond to the prameter buffer and the return
code, which are typically EAX and EBX.
The format of the parameter buffer is defined in the kernel
driver so we implement the same interface here in order to be
compatible.
GSMI_CMD_HANDSHAKE: this is an early call that it does to try
and detect what kind of BIOS is running.
GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that
has event type and data. The kernel-specific events are
translated here and raw events are passed through as well which
allows any run-time event to be added for testing.
GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log.
First the gsmi driver must be enabled in the kernel with
CONFIG_GOOGLE_GSMI and then events can be added via sysfs
and events are automatically generated for various kernel
shutdown reasons.
These can be seen in the event log as the 'Kernel Event' type:
169 | 2012-06-23 15:03:04 | Kernl Event | Clean Shutdown
181 | 2012-06-23 16:26:32 | Kernl Event | Oops

In CMOS the count is prefixed with a 16bit signature and

This counter is incremented in sandybridge early_init which is
called by romstage. It is incremented early in order notice
when reboots happen after memory init.
The counter is then logged when ELOG is initialized and will

Reboot a few times and look for 'System boot' events in the

This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.
It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.
A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.
The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.
ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign
And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions. This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.
This is a large commit and by itself it just provides a new
driver that is made available to coreboot. Without additional
patches it is not very useful, but the end result is an event
log that will contain entries like this:
171 | 2012-06-23 16:02:55 | System boot | 285
172 | 2012-06-23 16:02:55 | EC Event | Power Button

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.

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.

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.

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.

Allow user to add 'subsystemid <vendor> <device> [inherit]' to devicetree.cb for
PCI and PCI domain devices.
Example:
device pci 00.0 on
subsystemid dead beef
end
If the user wants to have this ID inherited to all subdevices/functions,
he can add 'inherit', like in the following example:
device pci 00.0 on
subsystemid dead beef inherit
end
If the user don't want to inherit a Subsystem for a single device, he can
specify 'subsystemid 0 0' on this particular device.

The K8T800 is almost identical to the K8T800Pro, also added to this patch.
The K8T800_OLD is also defined, which is an older version of the K8T800,
but which has no driver and early HT code yet. Also extended the K8M890 VGA
driver to work for the K8M800 (not tested). According to the datasheet, the
K8T890 and K8T800 are similar enough to be able to use the same
initialization code. At least for the K8T800, this is sufficient to have
a working HT link with the CPU, and to initialise the V-Link to the
southbridge.

the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

- Add proper "virtual LDN" handling for the LDNs that need it (i.e., those
that don't have their "enable" bit in bit 0 of the 0x30 register).
- Fix various I/O masks in the pnp_dev_info[] array as per
datasheet. Add missing PNP_IRQ0 to the W83627DHG_ACPI LDN.
W83627EHG:
- Similar to W83627DHG, improve the "virtual LDN" setup a bit (it was
mostly implemented already, though).
- Add missing PNP_IRQ0 to the W83627EHG_ACPI LDN.
Also: Fix up devicetree.cb of all boards using W83627DHG/W83627EHG to adapt
for the virtual LDNs.
include/device/pnp.h: Add comment that 'function' (which refers to the
LDN and should probably be renamed later) has to be at least 16 bits
wide. In theory LDNs could use u8, but due to the virtual LDN info being
encoded in the "high byte" of 'function' it must be at least u16.
asrock/939a785gmh/romstage.c: Drop unused GPIO6_DEV.

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.

-- When building for UMA, reduce the limit for DRAM below 4GB
from E0000000 to C0000000. This is needed to accomodate the
UMA frame buffer.
-- Correct problem where msr C0010010 bits 21 and 22 (MtrrTom2En

-- Enable TOM2 only if DRAM is present above 4GB.
-- Use AMD Tom2ForceMemTypeWB feature to avoid the need for
variable MTRR ranges above 4GB.
-- Add above4gb flag argument to function x86_setup_var_mtrrs. Clearing
this flag causes x86_setup_var_mtrrs() to omit MTRR ranges for
DRAM above 4GB. AMD systems use this option to conserve MTRRs.
-- Northbridge.c change to deduct UMA memory from DRAM size reported
by ram_resource. This corrects a problem where mtrr.c generates an
unexpected variable MTRR range.
-- Correct problem causing build failure when CONFIG_GFXUMA=1 and
CONFIG_VAR_MTRR_HOLE=0.
-- Reserve the UMA DRAM range for AMD K8 as is already done for AMD
family 10h.

Root cause: After function STOP_CAR_AND_CPU disables cache as
ram, the cache as ram stack can no longer be used. Called
functions must be inlined to avoid stack usage. Also, the
compiler must keep local variables register based and not
allocated them from the stack. With gcc 4.5.0, some functions
declared as inline are not being inlined. This patch forces
these functions to always be inlined by adding the qualifier
__attribute__((always_inline)) to their declaration.
