[PATCH 0/7] ARM: stm32mp: bbu: add FIP update handler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



STM32MP1 BootROM boots from GPT partition fsbl1 or fsbl2 on SD-Card and
from boot partition on eMMC. Recent TF-A without legacy image support will
then look in a GPT partition named fip in the user area.

With recent patches[1], TF-A will also check offset SZ_256K in the boot
partition to see if the FIP is there.

Add a barebox_update handler that covers these scenarios.

The TF-A patches are not yet upstream, but have all maintainer ACKs and
will likely be part of TF-A v2.8.

Ahmad Fatoum (7):
  bbu: move barebox_update eMMC boot handling into common code
  bbu: use free(NULL) to simplify function cleanup
  bbu: add flag for enabling eMMC boot ack
  bbu: export bbu_std_file_handler for use in custom handlers
  filetype: differentiate between STM32MP FSBL and SSBL images
  ARM: stm32mp: bbu: add FIP update handler
  fastboot: support TF-A FSBL and FIP images for barebox update
