[PATCH next v6 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.
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

Add RSACLK enable for ACRY, the HW RSA/ECC crypto engine of ASPEED AST2600 SoCs.
As ACRY and HACE share the same reset control bit, we do not perform the reset-hold-n-release operation during their clock ungating process. Instead, only reset release is conducted to prevent mutual interference.

AST2600 leverages the FIT hash/signature verification to fulfill secure boot trust chain. To improve the performance and save SW code size for those crypto operations, the two HW crypto engine, HACE and ACRY, are enabled.
However, both of the engines can only access to data stored in DRAM space. Therefore, we need to move the FIT image into DRAM before the booting.
This patch update the CONFIG_BOOTCOMMAND to execute the pre-defined ENV variable which consists of FIT image copy to memory and booting.
