commit aa5db60b3c55b1898349b37acfe6c08ed024e4f8 Author: Daisuke Nojiri dnojiri@chromium.org Date: Fri Sep 23 17:40:15 2016 -0700
marvell/mvmap2315: Compose BOOTBLOCK region
This patch adds a Makefile rule for mvmap2315 to install a BDB and bootblock code in the BOOTBLOCK region. The resulting BDB has a header and data both signed by a RSA-4096 key.
BUG=chrome-os-partner:57889 BRANCH=none TEST=emerge-rotor coreboot and examined the output binary. Booted coreboot.rom.
