Hi,
SPL framework is used to support multi-stage booting. Where first level boot loader is created via SPL having relocate_code() function. I am working on a Freescale's SoC which has less internal SRAM. I don't want to use relocate_code() as to support this function, I need to reduce SPL bin to SRAM/2 size.
is there way to avoid relocate_code function ?
I tried with below sequence, but it is not working for me :(
.globl relocate_code relocate_code: mr r1,r3 /* Set new stack pointer */ mr r9,r4 /* Save copy of Init Data pointer */ mr r10,r5 /* Save copy of Destination Address */
GET_GOT #ifndef CONFIG_SPL_BUILD
-- -- #endif .globl in_ram in_ram:
The reason is bss "variables" which are mapped to 0x0000_0000 onwards because "bss"section are mapped after 0xfffffffc in lds. They are not available during SPL execution. is there way to relocate bss section in the execution range of SPL?
Please advice.
