[PATCH v2 00/14] aspeed: Support secure boot chain with FIT image verification

[Chia-Wei Wang]

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 ARCY are also added for AST26xx SoCs.

As HACE and ARCY 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.
