Previously broadwell used a romcc bootblock and starting verstage in
romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also
possible to have a separate verstage.
This selects using a separate verstage by default but still keeps the
option around to use verstage in romstage.
With a separate verstage the romstage becomes an RW stage.
The mrc.bin however is only added to the RO COREBOOT fmap region as it
requires to be run at a specific offset. This means that coreboot will
have to jump from a RW region to the RO region for that binary and
back to that RW region after that binary is done initializing the
memory.

This puts the cache-as-ram init in the bootblock.
Before setting up cache as ram the microcode updates are applied.
This removes the possibility for a normal/fallback setup although
implementing this should be quite easy.
Setting up LPC in the bootblock to output console on SuperIOs is not
done in this patch, therefore BOOTBLOCK_CONSOLE is not yet selected.

As of CL:1605641, vboot2 code should be used for setting and
checking display init state. Remove all vboot1 OPROM-related
code, and use the vboot2 display init code which has already
been added in previous commits.
coreboot should not be reading vboot NVRAM flags directly.
Remove the function vboot_wants_oprom(), and instead rely on
display_init_required(), which uses the
VBOOT_WD_FLAG_DISPLAY_INIT value stored in
vboot_working_data.flags, initialized during verstage.
Note that this means in the case of CONFIG_VBOOT=y, the return
value of display_init_required() can only be trusted after
verstage has been executed. This should not be a problem
assuming that all display initialization occurs in ramstage.

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").

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().
