Duncan Laurie 87abeff334 Change flashmap base to reflect new FMAP in U-boot
The RO_FMAP base moved from 0x5f0000 to 0x610000.

Also update Kconfig default and add a descripton so
the default can be changed by boards.

Duncan Laurie 86bf3f518f ELOG: Find flash base in FMAP if possible
Now that we have FMAP support in coreboot use it to find the
offset in flash for ELOG to use.

If coreboot has elog configured with a smaller size then use
that over the FMAP size.  This is because I set aside a 16KB
region in the FMAP but we only use 4KB of it to keep the impact
to boot/resume speed to a minimum.

FMAP: Found "FMAP" version 1.0 at ffe10000.
FMAP: base = 0 size = 800000 #areas = 32
FMAP: area RW_ELOG found
FMAP:   offset: 3f0000
FMAP:   size:   16384 bytes
FMAP: No valid base address, using 0xff800000
ELOG: base=0x003f0000 base_ptr=0xffbf0000
ELOG: MEM @0x00190ad8 FLASH @0xffbf0000
ELOG: areas are 4096 bytes, full threshold 3072, shrink size 1024

Stefan Reinauer 357bb2daf0 SandyBridge/IvyBridge: Use flash map to find MRC cache
Until now, the MRC cache position and size was hard coded in Kconfig.
However, on ChromeOS devices, it should be determined by reading the
FMAP.

This patch provides a minimalistic FMAP parser (libflashmap was too
complex and OS centered) to allow reading the in-ROM flash map and
look for sections.

This will also be needed on some partner devices where coreboot will
have to find the VPD in order to set up the device's mac address
correctly.

The MRC cache implementation demonstrates how to use the FMAP parser.

Duncan Laurie 8de884424c ELOG: Fix reporting of developer/recovery modes
Recent changes in EC/Vboot/U-boot have completely broken
the logging of developer and recovery modes.

Recovery mode may not be in VBNV, so if that is zero and
yet we are in recovery mode then assume it is there because
the button/key was pressed.

Since there may not be any actual developer mode switch
we look if option rom is loaded and the system is not
in recovery mode and consider that as developer mode.

Stefan Reinauer be1ef2329e chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared Data
coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

describing the GPIOs. Hence, only keep that array in the mainboard
ChromeOS directory and move everything else to generic ChromeOS ACPI

Stefan Reinauer 984f9540c0 ChromeOS: Remove remnants of FDT support
Originally, on ChromeBooks, coreboot would provide a modified
u-boot device tree (FDT) to u-boot in CBMEM. However, u-boot
can now create all the information it needs from the coreboot
table and add it to its device tree itself. This means we can
drop this (anyways unused) code.

Stefan Reinauer 3008bbadcb Add TPM support to coreboot
and initialize the TPM on S3 resume

This patch integrates the TPM driver and runs TPM resume upon an ACPI S3
resume without including any other parts of vboot.

We could link against vboot_fw.a but it is compiled with u-boot's CFLAGS
(that are incompatible with coreboot's) and it does a lot more than we
want it to do.
