f7bfc34942 intel: Remove GFXUMA and related global variables
Remove use of global variables uma_memory_base and uma_memory_size
from builds with Intel northbridges, as these variables can be kept
within the chipset or even as stack locals.

Intel platforms have no functional implemenation for option GFXUMA.
If we did implement some choice between external and integrated graphics,
it needs to be named in less obscure fashion.

This defines new board_info entry 'Vendor name' to be displayed in place of, or
in addition to, the CONFIG_VENDOR string 'Google'.

Also flag these as flashrom accessible SPI without socket. Instructions to
disable flash write-protection can be found at Chromium developer documentation.

fd33781fbf Move ARCH_* from board/Kconfig to cpu or soc Kconfig.
CONFIG_ARCH is a property of the cpu or soc rather than a property of the
board. Hence, move ARCH_* from every single board to respective cpu or soc
Kconfigs. Also update abuild to ignore ARCH_ from mainboards.

ab56b3b11c ChromeOS: Remove oprom_is_loaded

Implement this feature without dependency to CHROMEOS option

spd.bin can reside anywhere in CBFS, and we only use CBFS APIs to

can collide with mrc.bin or mrc.cache on some boards. Do not use a
specific position for spd.bin, but instead let cbfstool find the
optimal placement.

Ability to choose compatibility mode is interesting for testing payloads and

As per comments
"ide_legacy_combined # TODO: Does nothing since

The "combined" mode was removed. It wasn't used by any mobo and the code for
it is almost identical to IDE one other than few bits relating to interrupt
handling and ISA mode.

b32816e9a5 Remove PCI_ROM_RUN option
The main purpose of option rom is to supply int* handlers.
But supplying those is outside of coreboot scope and if someone needs those
they should run SeaBIOS anyway which runs the option roms wonderfully.

Running VGA oprom is kept because they're needed to init graphics.

This patch still keeps the options to include the option roms to make them
available to SeaBIOS.

Use them. Also, since panels seem to set bits per color instead of bits

Add helpful comment because people don't always believe we need to set
the pallette.

While we're at it, fix a problem that caused it to not compile.

3e4e303858 Unify coreboot table generation
coreboot tables are, unlike general system tables, a platform
independent concept. Hence, use the same code for coreboot table
generation on all platforms. lib/coreboot_tables.c is based
on the x86 version of the file, because some important fixes
were missed on the ARMv7 version lately.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

b3b72f350e link/graphics: Add support for EDID
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.

a95a13bd47 link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.

As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.

A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.

The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.

The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.

This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.

i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

ec2d914e19 link/graphics: implement a palette setting operator
Add a  new operator, P, for the state machine, meaning
implement a palette fill.

Implement a function (palette) that fills the palette when the
P operator is hit.

This replaces 256 lines in the state machine table with 1.

665e3d23f0 link/graphics: add functions to support aux channel communications
For full integration of FUI into coreboot, we need aux channel
communcations.  The intel_dp.c is a file taken from Linux and is
used for aux channel comms.  This file has been cut down to work
with coreboot.  For now it is associated with the link mainboard
until we get a better handle on how this all fits together.  This
code is almost certainly usable on other platforms in the long term.
But one step at a time.

aeda4b8c0a src/mainboard: Drop redundant CHIP_NAME again for new ports
Since commit »Drop redundant CHIP_NAME in mainboard.c« (a93c3fe7) [1]
`CHIP_NAME` is unneeded for mainboards as the name is composed
automatically in `src/devices/root_device.c` from the strings in
Kconfig.

Unfortunately the ports for Google Butterfly, Link and Parrot as
as well as IEI PM-LX2-800-R10 introduced CHIP_NAME again. So drop
it again too.
