What is the meaning of the offset at 0x1000 ? Is there something at IRAM_BASE_ADDR ?
I thought CONFIG_SYS_INIT_SP_ADDR is assigned to stack pointer (sp) which decrease the address. Is it not the case?
Boards should define CONFIG_SYS_INIT_RAM_ADDR (the start address) and CONFIG_SYS_INIT_RAM_END (actually the size of the initial RAM).
I'm working on patches that will auto-calculate CONFIG_SYS_INIT_SP* from that.
