Ryu sensor hub has asymectric RO/RW images. The first one is very limited
(not i2c master, no sensor drivers, gesture recognition).
Image size is alter to offer more space for the RW firmware image,
compiled with ryu_sh board.
To write RO image and basic RW image:
flashrom -V -p ec:type=sh,block=0x800 --fast-verify -w /tmp/ryu_sh_loader/ec.bin
To write the expected RW image:
flashrom -V -p ec:type=sh,block=0x800 --fast-verify -w -i EC_RW:/tmp/ryu_sh/ec.bin

EAh is used at the end marker for calculating hash in EC.
The extra EAh make hash calculated by EC different from calculated in host
by sha256sum for the RW image. The RO image is fine.
Fix a comment, no A,B images anymore.

This file will soon contain the exhaustive list of all CONFIG defines
and their descriptions.
Chip-level configs are renamed to config_chip.h to avoid naming

All of our current EC configs have RO and a single RW image. Calling
that image 'A' is confusing, particularly when combined with EC
software sync (where the RW image is updated from either the A or B AP
RW firmware). So, rename it.
This changes all the build artifacts and constants. Internal EC
commands and host commands still refer to A/B; that will be fixed in
part 2.

And if RW B isn't enabled, it's not even linked.

To accomodate our growing code, image RW.B is removed so that RO and
RW.A can both have 60K space. This is just a temporary solution. Add
RW.B back when we have enough space for all three images.
Also add license header to firmware_image.lds.S so that repo does not
complain about it.
