[TF-A] How to change the address of region "RAM" in BL31?

Hi all,

I want to add some big data structures in BL31 (e.g., create a large uint32_t array). Also, I reserve a secure memory space (assume it is 0xa000_0000 - 0xb000_0000) by configuring TZASC.

Now, the BL31 says

build/fvp/debug/bl31/bl31.elf section `.bss' will not fit in region `RAM' aarch64-none-elf-ld: BL31 image has exceeded its limit. aarch64-none-elf-ld: region `RAM' overflowed by 458752 bytes

It looks like that the previous RAM cannot hold my big data structures. If I want to add my reserved region into RAM (so I may allocate these data into the reserved region), what should I do?

Sincerely, Wang
