This change udpates FMAP to wrap MRC training data in RW_PRESERVE section so that we don't lose the data when performing full firmware updates on octopus. BUG=b:117882029 TEST=Verified that chromeos-firmwareupdate doing full firmware update preserves training data on octopus.

# Currently, it is required that the BIOS region be a multiple of 8KiB.
|
|
# This is required so that the recovery mechanism can find SIGN_CSE
|
|
# region aligned to 4K at the center of BIOS region. Since the
|
|
# descriptor at the beginning uses 4K and BIOS starts at an offset of
|
|
# 4K, a hole of 4K is created towards the end of the flash to compensate
|
|
# for the size requirement of BIOS region.
|
|
# FIT tool thus creates descriptor with following regions:
|
|
# Descriptor --> 0 to 4K
|
|
# BIOS --> 4K to 0xf7f000
|
|
# Device ext --> 0xf7f000 to 0xfff000
