[U-Boot] [PATCH v2 01/11] arm: mvebu: Use default reg base address for SPL on A38x

Stefan Roese sr at denx.de
Mon Jul 20 10:17:43 CEST 2015


On A38x switching the regs base address without running from
SDRAM doesn't seem to work. So let the SPL still use the
default base address and switch to the new address in the
mail u-boot later.
