Nico Huber 904a0ec9d0 Don't use 64-bit constant 0x100000000 in linker scripts
The constant value 0x100000000 is used in linker scripts to calculate
offsets from the end of 32-bit-addressed memory. There is nothing
wrong with it, but 32-bit versions of ld do the calculation wrong.

If the IOAPIC entry in the MPTABLE is incorrect, the user will notice

is even worse.

Anyway, I believe at least this will cause warnings.
"resv" is a member of a union, not of acpi_addr_t. So it should be
wrapped by a brace in the initializer.

Denis 'GNUtoo' Carikli 7c2d058d61 Fix the location of "Setting variable MTRR" printk.
Without that fix the debugging is harder because the person debugging
  coreboot will see the following twice(note the repeated MTRR number):
    Setting variable MTRR 0, base:    0MB, range: 4096MB, type WB
    [...]
    Setting variable MTRR 1, base: 4096MB, range:  512MB, type WB
    Setting variable MTRR 1, base: 4608MB, range:  256MB, type WB
    Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC
  instead of the following twice:
    Setting variable MTRR 0, base:    0MB, range: 4096MB, type WB
    [...]
    Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC

Thanks to kmalkki on #coreboot's Freenode IRC channel for the idea:
  May 25 23:57:17 <kmalkki>	I would add (move) that "Setting variable MTRR..." debug at the end of set_var_mtrrs()

Vadim Bendebury 3b3a1a1ee6 Provide functions to access arbitrary GPIO pins and vectors
This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.

As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.

There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.

When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.

Stefan Reinauer bb31f3a24a Drop config variable CPU_MODEL_INDEX
It's only used in the ACPI generator for Sandybridge/Ivybridge CPUs
and the code can easily be changed to not rely on any Kconfig magic.

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 88fc0b9e8d Sandybridge: Remove remnants of FDT support from MRC cache code
Originally, ChromeBooks would get the offset of the MRC cache
from an entry in the u-boot device tree. Not everyone wants to
use u-boot on Sandybridge systems, however.
Since the new code (based on Kconfig) is now fully working, we
can drop the u-boot device tree remnants.
