e35b6497f4 x86: Make coreboot sysinfo available to any x86 board
It is possible to boot U-Boot for chromebook_coral either 'bare metal' or
from coreboot. In the latter case we want to provide access to the coreboot
sysinfo tables. Move the definitions into a file available to any x86
board.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

1b4f25ff8e x86: ivybridge: Add support for early GPIO init
When not relying on Coreboot for GPIO init the GPIOs must be set up
correctly. This is currently done statically through a rather ugly method.
As the GPIOs are figured out they can be moved to the device tree and set
up as needed rather than all at the start.

In this implementation, board files should call ich_gpio_set_gpio_map()
before the GPIO driver is used in order to provide the GPIO information.
We use the early PCI interface so that this driver can now be used before
relocation.

6dbe0cce3f x86: Enable coreboot timestamp facility support in u-boot.
This change turns on the code which allows u-boot to add
timestamps to the timestamp table created by coreboot.

Since u-boot does not use the tsc_t like structure to represent
HW counter readings, this structure is being replaced by 64 bit
integer.

The timestamp_init() function is now initializing the base timer
value used by u-boot to calculate the HW counter increments.

Timestamp facility is initialized as soon as the timestamp table
pointer is found in the coreboot table. The u-boot generated
timer events' ID will start at 1000 to clearly separate u-boot
events from coreboot events in the timer trace.

63f559cd12 x86: Import code from coreboot's libpayload to parse the coreboot table
This change also forces the lib_sysinfo structure to be in the .data
section. Otherwise it ends up in the .bss section. U-boot assumes that it
doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.
