This patch series intends to provide a secure boot chain from SPL to Linux kernel based on the hash and signature verification of FIT image paradigm.
To improve the performance and save code size (SPL is limited to 64KB due to HW-RoT), the drviers of two HW crypto engine HACE and ACRY are also added for AST26xx SoCs.
As HACE and ACRY can only access to DRAM space, additional configuration and boot command are also updated according to move each FIT image before its booting.
In addition, the common code of FIT image hash algorithm lookup is also revised to leverage the HW accelerated calculation.
v8: - include reviewers' tag - address comments suggested by Joel - move this patch series back to the master branch as DM_HASH has been merged
v7: - fix missing interrupt status clear for ACRY RSA operation
v6: - fix parameter comment for v5 update
v5: - fix inconsistent parameter name due to parallel patch work
v4: - add new DM_HASH based driver for Aspeed HACE - remove SPL board init, which was originally used to probe non-DM HACE driver - fix typo of ARCY to ACRY - refactor defconfig based on the new Kconfig of U-Boot next branch
v3: - add SW work around for HACE HW DMA issue by resetting HACE - add reset control for HACE device tree node - sync all of the HACE error message to use debug()
v2: - update commit authors
