[PATCH 6/6] memory: reserve from start_addr_sp to relocaddr

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

Reserve the memory from gd->start_addr_sp - CONFIG_STACK_SIZE to
gd->relocaddr instead of gd->ram_top. This allows platform specific
relocation addresses to work without unnecessarily painting over a large
range.
