Instead of verifying the CRC before every access of the boot data, verify the CRC once at startup and set a flag to indicate the boot data is valid. Also add a framework to support multiple boot protocol versions. Firmware declares the maximum supported protocol version using a version byte in the boot data header. The bootloader chooses the highest version supported by it and the firmware when deciding what boot protocol to use. Change-Id: I810194625dc0833f026d2a23b8d64ed467fa6aca |
