rockchip: Use common bss and stack addresses on RK3588
Currently the following memory layout is typically used on RK3588:
[ 0, 256K) - SPL binary
[ 256K, 2M) - TF-A / reserved
[ -X, 4M) - SPL pre-reloc stack (SPL_STACK)
[ 3.5M, 4M) - pre-reloc malloc heap (SPL_SYS_MALLOC_F_LEN)
[ -X, 6M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 5M, 6M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
[ 10M, +X) - U-Boot proper binary (TEXT_BASE)
[ -X, 12M) - U-Boot proper pre-reloc stack (CUSTOM_SYS_INIT_SP_ADDR)
[11.5M, 12M) - pre-reloc malloc heap (SYS_MALLOC_F_LEN)
[ 64M, +16K) - SPL bss (SPL_BSS_START_ADDR, SPL_BSS_MAX_SIZE)
SPL can safely load U-Boot proper + FDT to [10M, 11.5M) with this layout.
However, on ROCK 5A the SPL stacks is overlapping:
[ -X, 16M) - SPL pre-reloc stack (SPL_STACK)
[15.5M, 16M) - pre-reloc malloc heap (SPL_SYS_MALLOC_F_LEN)
[ -X, 16M) - SPL reloc stack (SPL_STACK_R_ADDR)
[ 15M, 16M) - reloc malloc heap (SPL_STACK_R_MALLOC_SIMPLE_LEN)
Because bind and probe udevice instanses is allocated on the pre-reloc
malloc heap, there is going to be an overlap when reloc malloc heap
reaches close to 512 KiB of usage.
Migrate to use common bss, stack and malloc heap size and addresses to
mitigate these limitations and allow for a larger U-Boot proper size.
