This patch adds a workaround for Samsung C-die 2G/4G memory chips.
For unknown reasons, some boards with Samsung LP3 memory chips
could not pass early CS/CMD training. MRC has to change the
granularity from 16 ticks to 8 ticks, which implies bad margin
with this memory chip. Another way is to enhance the drive
strength for CS. This patch is to enhance the drive strength for CS
and CMD. Enhancing the drive strength for CMD could gain margin abaout
3 more ticks. Root cause needs to be further investigated with memory
vendor.

The gpio table is only used by depthcharge, and depthcharge rarely
has a need for the "recovery" gpio. On a few boards it does use the
gpio as a signal for confirming physical presence, so on that boards
we'll advertise the board as "presence".
All these strings probably should have been #defines to help avoid
typos (e.g., the "ec_in_rw" in stout seems questionable since everybody
else uses "EC in RW").

Currently it trusts anything except usb, but now there's a need
to distrust ec-based ps/2 keyboards that are associated with untrusted

This cpu_index() implementation assumes that cpu_index() function
might always getting called from coreboot context (ESP stack
pointer will always refer to coreboot).
This might not be true in case of proposed PI spec MP_SERVICES_PPI
implementation, where FSP context (stack pointer refers to fsp)
will request to get cpu_index(), natural alignment logic will
use ESP and retrieve struct cpu_info *ci from (stack_top - 8 byte).
This is not the place where cpu_index is actually stored by
ramstage c_start.S
Hence this patch tries to remove those dependencies while retrieving
cpu_index(), rather it uses cpuid to fetch lapic id and matches with
cpus_default_apic_id[] variable to return correct cpu_index().

any rogue definitions that may have already been set by vendorcode
headers.
This is ugly and should only be a stopgap... it would be nice if someone
maintaining those vendorcode parts could eventually replace it with a
better solution. One option would be to use a "guard header" for every
vendorcode header we want to pull into normal coreboot code which would
chain-include the vendorcode header and then undefine anything that
