Add function to respond to fastboot flash and erase. Flash writes the
previously downloaded image to indicated partition. Erase clears the
indicated partition. fb_flash and fb_erase are essentially wrappers
for fb_mmc_flash_write and fb_mmc_erase, which are implemented in
common/fb_mmc.c.
Added common/fb_common.c, where fastboot_okay/fail are implemented.
common/fb_mmc.c assumes fasboot_okay() and fastboot_fail() are
implemented, but they were tied to the fastboot USB implementation.
This refactor adds the response string as a parameter to
fastboot_okay/fail, instead of modifying a global.
Bug: 31887729
Test: FLASH:
- Create file "foo" containing 2048 chars = "-"
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP flash misc foo" from host
- From U-boot console, read into memory the first 4 blocks from
misc partition, observe each byte is "-".
ERASE
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP erase misc" from host
- From U-boot console, read into memory many blocks from misc
partition, observe each byte is 0x00
Configs that use fastboot USB implementation still build.
