The commit b583348ca8c8 ("image: fit: Align hash output buffers") places the hash output buffer at the .bss section. However, AST2600 by default executes SPL in the NOR flash XIP way. This results in the hash output cannot be written to the buffer as it is located at the R/X only region.
We need to move the .bss section out of the SPL body to the DRAM space, where hash output can be written to. This patch includes:
- Define the .bss section base and size
- A new SPL linker script is added with a separate .bss region specified
- Enable CONFIG_SPL_SEPARATE_BSS kconfig option
