From 745325a97d172a71dea4ec7528224ed63973d601 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 9 Jun 2014 11:36:57 +0200 Subject: sunxi: Add sun4i support Add support for the Allwinner A10 SoC also known as the Allwinner sun4i family, and add the Cubieboard board which uses the A10 SoC. Compared to sun7 only the DRAM controller is a bit different: -Controller reset bits are inverted, but only for Rev. A -Different hpcr values -No MBUS on sun4i -Various other initialization changes Signed-off-by: Henrik Nordstrom Signed-off-by: Stefan Roese Signed-off-by: Oliver Schinagl Signed-off-by: Hans de Goede Acked-by: Ian Campbell --- board/sunxi/Makefile | 1 + board/sunxi/dram_cubieboard.c | 31 +++++++++++++++++++++++++++++++ 2 files changed, 32 insertions(+) create mode 100644 board/sunxi/dram_cubieboard.c (limited to 'board/sunxi') diff --git a/board/sunxi/Makefile b/board/sunxi/Makefile index cbf8f086a9..4902d70834 100644 --- a/board/sunxi/Makefile +++ b/board/sunxi/Makefile @@ -10,4 +10,5 @@ # obj-y += board.o obj-$(CONFIG_SUNXI_GMAC) += gmac.o +obj-$(CONFIG_CUBIEBOARD) += dram_cubieboard.o obj-$(CONFIG_CUBIETRUCK) += dram_cubietruck.o diff --git a/board/sunxi/dram_cubieboard.c b/board/sunxi/dram_cubieboard.c new file mode 100644 index 0000000000..399028ca96 --- /dev/null +++ b/board/sunxi/dram_cubieboard.c @@ -0,0 +1,31 @@ +/* this file is generated, don't edit it yourself */ + +#include +#include + +static struct dram_para dram_para = { + .clock = 480, + .type = 3, + .rank_num = 1, + .density = 4096, + .io_width = 16, + .bus_width = 32, + .cas = 6, + .zq = 123, + .odt_en = 0, + .size = 1024, + .tpr0 = 0x30926692, + .tpr1 = 0x1090, + .tpr2 = 0x1a0c8, + .tpr3 = 0, + .tpr4 = 0, + .tpr5 = 0, + .emr1 = 0, + .emr2 = 0, + .emr3 = 0, +}; + +unsigned long sunxi_dram_init(void) +{ + return dramc_init(&dram_para); +} -- cgit
