that this area isn't changing after every S5 entry there's no

- ELOG area reduced by 4KiB for subsequent area alignment. In practice
this doesn't matter because the elog library only uses 4KiB bytes.
16KiB->12KiB is a nop.
- Moved RW_NVRAM for subsequent alignment.
- Most importantly, RW_SECTION_(A|B) are aligned to 64KiB boundaries
and sized to 64KiB multiples. This ensures updates don't need a
read-modify-write that could force a system into recovery if
an inopportune power event occurred.

Gru only uses USB 2.0 in firmware to avoid all the madness associated
with Type-C port orientation and USB 3.0 tuning. We do this by isolating
the SuperSpeed lines in the Type-C PHY so it looks like they aren't
connected to the device.
Unfortunately, some devices seem to already get "locked" into SuperSpeed
mode as soon as they detect Rx terminations once, and can never snap out
again on their own. Since the terminations are already connected during
power-on reset we cannot disable them fast enough to prevent this, and
the only solution we found to date is to power-cycle the whole USB port.
Now, Gru's USB port power is controlled by the EC, and unfortunately we
have no direct host command to control it. We do however have a command
to force a certain USB PD "role", and forcing our host into "sink" mode
makes it stop sourcing power to the port. So for lack of a saner
solution we'll use this to work around our problem.

spi_slave structure in CAR_GLOBAL/data section, caller is expected to
manage the spi_slave structure. This requires that spi_flash drivers
maintain spi_slave structure and flash probe function needs to make a
copy of the passed in spi_slave structure.
