Hello all,
This series adds USB boot support to HS DRA7xx/AM57xx platforms.
We start by cleaning up DFU boot in SPL support. What is done in the first patch for DFU, if acceptable, should be done to the other boot modes.
The 4th patch is needed as on HS devices a header is added to the boot image that tells the ROM where to load this image. This only works for block device booting as the ROM can read the header and move the image into memory in steps. For streaming boot modes USB/ UART/NET the image is placed in memory as it is received from the media live. This means the header is ignored and the image has a fixed offset in memory.
For AM47xx we align the boot modes by making the offset for block device booting the same as the fixed offset for streaming boot modes, in this way only one defconfig is needed. For DRA7xx/AM57xx the signing tools will need to be updated to support specifying this address, when this is done the offset in the base HS defconfig can be moved to match the new offset and the defconfigs added here in patch 5 and 6 can be unified back into the base HS defconfig.
The last patch updates the docs for the same above.
Thanks, Andrew
Changes from v2: - Only use ISW_ENTRY_ADDR for system with a set default
Changes from v1: - Drop explicit UART boot support from DRA7xx as this cannot be tested
