Loading on an OMAP SOC requires that the first sector of the image have a
configuration header, and, when not an execute in place image, an additional
header which describes how big the image is and where it should be loaded.
This change adds some infrastructure to statically build that header using C
code, and to paste the header onto the front of coreboot.rom in a new top
level target file called MLO.
The configuration header we're using is as inert as possible, in line with
what U-Boot is doing. I think it could be used to give additional
configuration parameters to the built-in ROM on the SOC, but we don't need to
do that, and there didn't seem to be any actual documentation how to do that.
Because the header is built from C and is defined per CPU, it would be
possible to include extra settings in other CPUs if desired.
Adding a new top level build target is a bit disruptive, but should be
contained to the am335x directory and not interfere with other mainboards.

On ARM, there's frequently some firmware built into the SOC which runs
first and which loads other firmware like Coreboot from some other
media. To prevent the bootblock from having to know how to find and load
the ROM stage from what may be a complicated source (sd card,
netbooting, etc.), we can put the ROM stage immediately after the
bootblock and ensure that they're both loaded at the same time.
This change adjusts the Makefile.inc for ARM so that the ROM stage is put
into the image before any other files so that we know it comes first.
This changes the behavior of the CONFIG_UPDATE_IMAGE config option used
by abuild, although it's not entirely clear whether that's still used.

First copy over from SeaBIOS git repo, then adapt for coreboot:
Disable cpu/pci hotplug bits. Disable dynamic pci window.
Both depend on stuff in the SSDT tables created by SeaBIOS.
Bits are left in, but deactivated via #if 0, so it's easier
to see the differences when diffing the coreboot tables with
the SeaBIOS tables.
Adapt dsdt DefinitionBlock.
Enable acpi table generation in acpi_tables.c.
With this patch linux boots successfully with ACPI enabled.
It's not bug-free though. Missing cpu detection leads to
funky messages like this one:
weird, boot CPU (#0) not listed by the BIOS.
and SMP most likely wouldn't work either.

The following methods are implemented and tested against the power

* WAIT_EC_SC Wait for a bit in the EC_SC register

* RECV_EC_DATA Read one byte of data from the EC_DATA register
* EC_READ Read one byte from ec memory (through cmd 0x80)
* EC_WRITE Write one byte to ec memory (through cmd 0x81)
To use the provided methods, one should include `ec/acpi/ec.asl` in the

* EC_SC_IO I/o address of the EC_SC register

viatool is a utility for extracting useful for extracting certain configuration
bits on VIA chipsets and CPUs. It is a fork of inteltool.
viatool is currently focused on "quirks". Quirks are device configurations that
cannot be accessed directly. They are implemented as hierarchical configurations
in the PCI or memory address spaces (index/data register pairs). Such
configurations refer to hardware parameters that are board specific. Those
parameters would otherwise be difficult to extract from a system running the
vendor's firmware.
viatool also preserves inteltool's MSR dumps. VIA CPU and Intel CPU MSRs are
nearly identical.
