While in CCD, cr50 can be used to flash the AP and EC through USB. This change adds an endpoint that can be used to read, erase, and write to the AP and EC spi rom. Currently CCD is not enabled on cr50, so usb_spi access has to be enabled manually through the cr50 console. BUG=chrome-os-partner:50701 BRANCH=none TEST=manual On EC console run 'flash_tristate true' On cr50 console run 'usb_spi enable' Use 'flashrom -p raiden_debug_spi:target=EC' and 'flashrom -p raiden_debug_spi:target=AP' to interact with the AP and EC flash CQ-DEPEND=CL:342144 Change-Id: I9c31dab252a8bfbc498eaf64ac5c2f53ec9dde30 Signed-off-by: Mary Ruthven <mruthven@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/342511
