[PATCH next v5 00/12] aspeed: Support secure boot chain with FIT image verification

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.

 - fix inconsistent parameter name due to parallel patch work

 - 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

 - 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()

 - update commit authors
