[PATCH 0/7] ARM: add support for chainloading barebox inside FIP images

[Ahmad Fatoum]

For use on the STM32MP1, add a bootm handler for chainloading FIP
images. This removes the last remaining use case for SSBL .stm32 images,
after TF-A had dropped support late 2022.

Ahmad Fatoum (7):
  fip: add struct fip_image_desc::private_data
  fip: mark predefined toc_entries array const
  bootm: implement UIMAGE_IS_ADDRESS_VALID helper
  ARM: legacy: make architecture number unsigned
  ARM: introduce jump_to_linux helper
  ARM: add support for chainloading barebox inside FIP images
  ARM: stm32mp: retire non-FIP stm32mp_bbu_mmc_register_handler
