rockchip: Use common bss and stack addresses on RK3328
With the stack and text base used by U-Boot SPL and proper on RK3328 there is a high likelihood of overlapping when U-Boot proper + FDT nears or exceeded 1 MiB in size. Currently the following memory layout is typically used on RK3328: [ 0, 256K) - SPL binary [ 256K, 2M) - TF-A / reserved [ 2M, +X) - U-Boot proper binary (TEXT_BASE) [ -X, 3M) - U-Boot proper pre-reloc stack (CUSTOM_SYS_INIT_SP_ADDR) [ -8K, 3M) - pre-reloc malloc heap (SYS_MALLOC_F_LEN) [ -X, 4M) - SPL pre-reloc stack (SPL_STACK) [ -8K, 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) [ 32M, +8K) - SPL bss (SPL_BSS_START_ADDR, SPL_BSS_MAX_SIZE) SPL can safely load U-Boot proper + FDT to [2M, 4M-8K) with this layout. However, the stack at [-X, 3M) used during U-Boot proper pre-reloc is restricting the safe size of U-Boot proper + FDT to be less than 1 MiB. Migrate to use common bss, stack and malloc heap size and addresses to fix this restriction and allow for a larger U-Boot proper image size.
