        AMD CIMx SB800: Enable AHCI mode for SATA controller by default

        Reviewed-on: http://review.coreboot.org/2661

I forgot to update the help texts to the new SATA mode default. Do
so now.

Additionally note that help texts for `choice` do not seem to be
shown.

David Hendricks e85f4eb1b0 armv7: update sync barrier usage in dcache_op_set_way()
This moves the dsb() before the loop to sync any outstanding memory
accesses, and adds an isb() after the loop to ensure all outstanding
instructions are completed.

Aaron Durbin dc82fc5634 wtm2: auto-select CACHE_ROM
The WTM2 board has a fairly static configuration. As such
it's been tested to properly handle CACHE_ROM given the number
of MTRRs the boards' CPUs supports.

Paul Menzel b5146b394a AMD Inagua: Kconfig: Remove `WARNINGS_ARE_ERRORS` to treat warnings as errors
Now that the AMD Inagua builds without any warnigs, remove the
config option `WARNINGS_ARE_ERRORS` set to no by default from
the file `Kconfig` so warnings are treated as errors to prevent
code from being added in the future introducing warnings.

Aaron Durbin 53924240be x86: mtrr: optimize hole carving above 4GiB
There is an optimization that can take place when hole
carving in ranges above 4GiB. If the range is the last
range then there is no need to carve UC holes out from
the larger WB range.

This optimization also has the same assumption of choosing
WB as the default MTRR type: the OS needs to properly
handle accessing realloacted MMIO resources with PAT so
that the MTRR type can be overidden.

Below are results using a combination of options. The
board this was tested on has 10 variable MTRRs at its
disposal. It has 4GiB of RAM.

Aaron Durbin e383442943 x86: mtrr: add hole punching support
Some ranges would use less variable MTRRs if an UC area
can be carved off the top of larger WB range. Implement this
approach by doing 3 passes over each region in the addres space:
  1. UC default type. Cover non-UC and non-WB regions with respectie type.
     Punch UC hole at upper end of larger WB regions with WB type.
  2. UC default type. Cover non-UC regions with respective type.
  3. WB default type. Cover non-WB regions with respective type.
The hole at upper end of a region uses the same min alignment of 64MiB.

Below are results using a combination of options. The board this was
tested on has 10 variable MTRRs at its disposal. It has 4GiB of RAM.

Downstream payloads may need to take advantage of caching the
ROM for performance reasons. Add the ability to communicate the
variable range MTRR index to use to perform the caching enablement.

An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the coreboot tables. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.

Aaron Durbin 77a5b4046a x86: mtrr: add CONFIG_CACHE_ROM support
The CONFIG_CACHE_ROM support in the MTRR code allocates an MTRR
specifically for setting up write-protect cachine of the ROM. It is
assumed that CONFIG_ROM_SIZE is the size of the ROM and the whole
area should be cached just under 4GiB. If enabled, the MTRR code
will allocate but not enable rom caching. It is up to the callers
of the MTRR code to explicitly enable (and disable afterwards) through
the use of 2 new functions:
- x86_mtrr_enable_rom_caching()
- x86_mtrr_disable_rom_caching()

Additionally, the CACHE_ROM option is exposed to the config menu so
that it is not just selected by the chipset or board. The reasoning
is that through a multitude of options CACHE_ROM may not be appropriate
for enabling.

Aaron Durbin a75561415e resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]
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.

Aaron Durbin bb4e79a332 x86: add new mtrr implementation
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

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

Jens Rottmann 3926b4c520 AMD Inagua: add GEC firmware, document Broadcom BCM57xx Selfboot Patch format
The Broadcom BCM5785 GbE MAC integrated in the AMD Hudson-E1 requires a
secret sauce firmware blob to work.  As Broadcom wasn't willing to send us
any documentation (or a firmware adapted to our Micrel PHY) I had to figure
out everything by myself in many weeks of hard detective work.

In the end we had to settle for a different solution, the modified firmware
I devised for the Micrel KSZ9021 PHY on our early FrontRunner-AF prototypes
is no longer needed for the production version.  However the information
contained here might be very useful for others who'd like to use a
competing PHY instead of Broadcom's 50610, so it should not get lost.

And of course the unmodified, but now in large parts documented Selfboot
Patch is needed to get Ethernet on AMD Inagua.  The code introduced here
should make the Hudson's internal MAC usable without having to add the
proprietary firmware blob. - At least in theory.

Unfortunately we've been unable to actually test this patch on Inagua,
therefore the broadcom_init() call in mainboard.c was left commented out.
If you have the hardware and can confirm it works please enable it.

The fun thing is: as Broadcom refused to do any business with us at all,
or send us any documentation, we never had to sign an NDA with them.  This
leaves me free to publish everything I have found out.  :-)

.textfirst was directly called out in the linker script. However,

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

The rmodule code was developed when ramstage was linked using

are not referenced from any other object the link could start
by specifying the rmodule header object for ramstage. That,
however, is not the case as all ramstage objects are included
in the intermediate linked object. Therefore, the
ramstage_module_header.ramstage.o object file needs to be removed
from the object list for the ramstage rmodule.
