At least when building with the gnu toolchain, the headers the linker
automatically generate save space for the actual ELF headers in one of the
loadable segments. This creates two problems. First, the data you intended to
be at the start of the image doesn't actually show up there, it's actually the
ELF headers. Second, the ELF headers are essentially useless for firmware
since there's currently nothing to tell you where they are, and even if there
was, there isn't much of a reason to look at them. They're useful in userspace
for, for instance, the dynamic linker, but not really in firmware.
This change adds a PHDRS construct to each of the linker scripts used on ARM
which define a single segment called to_load which does not have the flag set
which would tell the linker to put headers in it. The first section defined in
the script has ": to_load" to tell the linker which segment to put it in, and
from that point on the other sections go in there by default.
BUG=None
TEST=Built and booted on nyan. Verified that the ROM stage was less than 18KB.

stage stayed the same size.

(There is supposedly also support in clang, although I haven't tried

This adds the option to put LPSS and SCC devices into ACPI mode
by saving their BAR0 and BAR1 base addresses in a new device
NVS structure that is placed at offset 0x1000 within the global
NVS table.
The Chrome NVS strcture is padded out to 0xf00 bytes so there
is a clean offset to work with as it will need to be used by
depthcharge to know what addresses devices live at.
A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and
the EMMC 4.5 IRQ is changed to 44.
New ACPI code is provided to instantiate the LPSS and SCC devices
with the magic HID values from Intel so the kernel drivers can
locate and use them.
The default is still for devices to be in PCI mode so this does
not have any real effect without it being enabled in the mainboard
devicetree.
Note: this needs the updated IASL compiler which is in the CQ now
because it uses the FixedDMA() ACPI operator.

On Tegra1x4 platforms, certain display-related registers
cannot be accessed unless the VPR registers are correctly
set up first. This allows the kernel graphics driver to
talk to the HW in the same manner on all Tegra SoCs.

The rambi board can only meet the SD card 2.0 specification.
Therefore, the controller capabilities need to be overridden
to match.

The SD card controller can have the capabilities it supports
to be overridden. Add two optional fields to the chip structure
to allow the mainboard to override the SD card controller
capabilities.

Bay Trail has 3 banks of gpios. Therefore, in order to
properly identify a gpio the specific bank number as well
as the GPIO within that bank is needed. The SPI
write-protect GPIO is GPIO 6 within the SUS bank (offset
0x2000).

Install the BL1 and set up the checksum in the Makefile instead of relying on
post processing. Import the exynos checksum script, split it in two and
simplify it significantly. Stop putting the CBFS header in the midst of the
bootblock so that it can be checksummed before CBFS is put together. Stop
saving space for it and leaving an anchor in the bootblock which nobody looks
for.
