[U-Boot] [PATCH v4 09/20] arm: kirkwood: Change naming of dram functions from km_foo() to mvebu_foo()
Stefan Roese
sr at denx.de
Wed Oct 22 12:13:13 CEST 2014
Additionally the SDRAM address decoding register address is not hard coded
in the C code any more. A define is introduced for this base address.
This makes is possible to use those gpio functions from other MVEBU SoC's
as well.
Signed-off-by: Stefan Roese <sr at denx.de>
Tested-by: Luka Perkov <luka at openwrt.org>
Acked-by: Prafulla Wadaskar <prafulla at marvell.com>
