With the RO region being added to software sync, up to two hashes will be requested during boot. Currently if vboot_hash has a valid hash when the EC gets an EC_VBOOT_HASH_GET host command then it will return that hash. When the EC gets a request for the RO hash after it has calculated the RW hash it returns the RW hash in the response. This change will add a check that the EC not only has a valid hash, but that it is for the correct region. BRANCH=none BUG=none TEST=Try to get the RO and RW hashes from depthcharge and make sure they match the values gotten using ectool Change-Id: I2449c8d79b4a74f4865dd1234fb253bcdac66a31 Signed-off-by: Mary Ruthven <mruthven@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/318861 Reviewed-by: Randall Spangler <rspangler@chromium.org>
