[PATCH] configs: ast2600: Move SPL bss section to DRAM space

[Neal Liu]

> 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
>
