Aaron Durbin 0f333071ef coreboot: infrastructure for different ramstage loaders
There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.

To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

Apparently there are two dunit IOSF ports -- 1 for each
channel. However, certain registers really on live in
channel 0. Thus, there was some changes to dunit support

Aaron Durbin 6ecdb68562 baytrail: add reset support
Bay Trail has the following types of resets it supports:
 - Soft reset (INIT# to cpu) - write 0x1 to I/O 0x92
 - Soft reset (INIT# to cpu)- write 0x4 to I/0 0xcf9
 - Cold reset (S0->S5->S0) - write 0xe to I/0 0xcf9
 - Warm reset (PMC_PLTRST# assertion) - write 0x6 to I/O 0xcf9
 - Global reset (S0->S5->S0 with TXE reset) - write 0x6 or 0xe to
   0xcf9 but with ETR[20] set.

While these are documented this support currently provides support
for 2nd soft reset as well as cold and warm reset.

Aaron Durbin 08a4613219 baytrail: adjust cache policy during romstage
The caching policy for romstage was previously using a 32KiB
of cache-as-ram for both the MRC wrapper and the romstage stack/data.
It also used a 32KiB code cache region. The BWG's limitations for
the code and data region before memory is up was wrong. It consists
of a 16-way set associative 1MiB cache. As long as enough addresses
are not read there isn't a risk of evicting the data/stack.

Now create a 64KiB cache-as-ram region split evenly between romstage
and the MRC wrapper. Additionally cache the memory just below
4GiB in CBFS size. This will cover any code and read-only data needed.

Aaron Durbin 189aa3e2ae baytrail: initialize punit
The punit is responsible for a number of things. Without
performing the sequence included it won't change processor
frequency when requested and apparently there are some bizarre
hangs introduced if this sequence isn't included either. Lastly,
this needs to come after microcode has been loaded. As that is
done in bootblock the ordering is correct.

One other side effect is that this fixes the graphics devices'
device id. Before it was showing up as the same device id of the

Shawn Nematbakhsh ebe3b3cfe2 baytrail: Add GPIO initial configuration infrastructure.
During ramstage, call mainboard_get_gpios to get initial GPIO configuration
from the mainboard code, then initialize GPIOs as requested.

BUG=chrome-os-partner:22863
TEST=Manual. Using bayleybay GPIO table, set UART GPIOs to 'function 1',
and verify UART still works after GPIO configuration. Also, verify
legacy GPIO config is functional by toggling test pin.

Ronald G. Minnich a8a133ded3 Add section header parsing and use it in the mk-payload step
This completes the improvements to the ELF file parsing code.  We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.

There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.

To maximize the ease of use for users, elf parsing is accomplished with
just one function:

int
elf_headers(const struct buffer *pinput,
	    Elf64_Ehdr *ehdr,
	    Elf64_Phdr **pphdr,
	    Elf64_Shdr **pshdr)

which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.

To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

BUG=None
TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same. This was also fully tested across all chromebooks for building and booting and running chromeos.
BRANCH=None

Aaron Durbin 452d31ad75 baytrail: introduce pattrs
The pattrs structure is intended for the supporting coreboot
code to reference instead of going back to the source of
the values (msrs, cpuid, etc). It essentially serves as a global
structure for collecting attributes about the platform/processor.

Additionally, the implementation provides a point during boot to
hoook work before device enumeration/initialization by providing
a init() function to soc_intel_baytrail_ops that is called before
device work in the boot state machine.

BUG=chrome-os-partner:22862
BUG=chrome-os-partner:22863
BRANCH=None
TEST=Built and booted. Noted pattrs output.
