memory: reserve from start_addr_sp to initial_relocaddr
Add a new global data struct member called initial_relocaddr. This
stores the original value of relocaddr, directly from setup_dest_addr.
This is specifically to avoid any adjustments made by other init
functions.
Reserve the memory from gd->start_addr_sp - CONFIG_STACK_SIZE to
gd->initial_relocaddr instead of gd->ram_top. This allows platform
specific relocation addresses to work without unnecessarily painting
over a large range.
