This changes the virt target so that it can be run with the -bios option
and a pflash backend for the flash. QEMU can now be run as follows:
qemu -M virt -m 1G -nographic -bios build/coreboot.rom \
-drive if=pflash,file=./build/coreboot.rom,format=raw
coreboot will start in DRAM, but still have a flash to put CBFS onto and
to load subsequent stages and payload from.

This is due to the fact that the libgcc.a library is compiled with the

Changing the code model of the GCC libraries to the medany code model
fixes the issue.

Since linux commit f9ba70535dc12d9eb57d466a2ecd749e16eca866
"[PATCH] Increase number of e820 entries hard limit from 32 to 128"
made in 2005 the number of e820 entries passed from the bootloader
is 128. Use the boot protocol version to check for support of
128 entries and use them if necessary.
Tested on IBM/SBP1:
Fixes booting a Linux payload when more than 32 entries are present
in the memory table, which can easily happen on a 4 socket platform.

Multiple links are unused throughout the tree and make the code more
confusing as an iteration over all busses is needed to get downstream
devices. This also not done consistently e.g. the allocator does not
care about multiple links on busses. A better way of dealing multiple
links below a device is to feature dummy devices with each their
respective bus.
This drops the sconfig capability to declare the same device multiple
times which was previously used to declare multiple links.

Currently autoport fills in USB current '0' if the detected setting
isn't one of the known settings. This works as 0 is a valid setting
from C point of view, but it's not supported on desktop PCs and on
mobile platform results in the lowest possible USB PHY gain. Thus
this might cause instabilities as the original firmware had stronger
USB drive currents and gain settings.
Add more known USB current fields to the map and generate a FIXME
as comment when the detected current isn't one of the known entries
instead of defaulting to 0.

On ChromeOS devices with updateable CSE firmware, the GPR0 (Global
Protected Range) register is used to ensure the CSE RO is write
protected even when the FLMSTR-based protection is temporarily disabled
by coreboot to allow updating the CSE RW. For more details see
Documentation/soc/intel/cse_fw_update/cse_fw_update.md
Therefore to allow modifying the CSE firmware from the CPU, the
descriptor must have both the FLMSTR-based protection disabled (which
can be done using ifdtool --unlock), and GPR0 disabled.
Add an ifdtool option for disabling GPR0. For now I've added support for
all platforms for which I have the SPI programming guide. Support for
more platforms can be added in the future if needed.
