Add EC_CMD_BLOB host command to pass opaque data around
This provides a way to experiment with or support random
functionality not specifically related to the normal EC
operation. With this, we can use a standard host command to pass
opaque data blobs between the AP and EC without specifying a
particular meaning to them.
BUG=chrome-os-partner:40969
BRANCH=none
TEST=make buildall
Nothing in the normal EC usage sends these messages. I have a
test/example program coming soon.
