MMC Firmware Code
MMC firmware code is organized into boot code and operational code, both of which are stored in a flash
module. Upon an MMC reset, the MMC executes the boot code and performs the following:
1 Self test to verify the status of its hardware and memory.
2 Performs a checksum of the operational code.
3 Set operational state that tells the boot block the firmware operate correctly.
Upon successful verification of the operational code checksum, the firmware will jump to the operational
code.
