From f84269c5c0ac3944532fce6fcadaeb7912d014e8 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 9 Jun 2014 11:36:58 +0200 Subject: sunxi: Add sun5i support Add support for the Allwinner A13 and A10s SoCs also know as the Allwinner sun5i family, and the A13-OLinuXinoM A13 based and r7-tv-dongle A10s based boards. The only differences compared to the already supported sun4i and sun7i families are all in the DRAM controller initialization: -Different hcpr values -Different MBUS settings -Some other small 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 | 2 ++ board/sunxi/dram_a13_oli_micro.c | 32 ++++++++++++++++++++++++++++++++ board/sunxi/dram_r7dongle.c | 31 +++++++++++++++++++++++++++++++ 3 files changed, 65 insertions(+) create mode 100644 board/sunxi/dram_a13_oli_micro.c create mode 100644 board/sunxi/dram_r7dongle.c (limited to 'board/sunxi') diff --git a/board/sunxi/Makefile b/board/sunxi/Makefile index 4902d70834..708363290a 100644 --- a/board/sunxi/Makefile +++ b/board/sunxi/Makefile @@ -10,5 +10,7 @@ # obj-y += board.o obj-$(CONFIG_SUNXI_GMAC) += gmac.o +obj-$(CONFIG_A13_OLINUXINOM) += dram_a13_oli_micro.o obj-$(CONFIG_CUBIEBOARD) += dram_cubieboard.o obj-$(CONFIG_CUBIETRUCK) += dram_cubietruck.o +obj-$(CONFIG_R7DONGLE) += dram_r7dongle.o diff --git a/board/sunxi/dram_a13_oli_micro.c b/board/sunxi/dram_a13_oli_micro.c new file mode 100644 index 0000000000..8154ea2ca9 --- /dev/null +++ b/board/sunxi/dram_a13_oli_micro.c @@ -0,0 +1,32 @@ +/* this file is generated, don't edit it yourself */ + +#include +#include + +static struct dram_para dram_para = { + .clock = 408, + .type = 3, + .rank_num = 1, + .density = 2048, + .io_width = 16, + .bus_width = 16, + .cas = 9, + .zq = 123, + .odt_en = 0, + .size = 256, + .tpr0 = 0x42d899b7, + .tpr1 = 0xa090, + .tpr2 = 0x22a00, + .tpr3 = 0, + .tpr4 = 0, + .tpr5 = 0, + .emr1 = 0, + .emr2 = 0x10, + .emr3 = 0, + +}; + +unsigned long sunxi_dram_init(void) +{ + return dramc_init(&dram_para); +} diff --git a/board/sunxi/dram_r7dongle.c b/board/sunxi/dram_r7dongle.c new file mode 100644 index 0000000000..59343cb2a5 --- /dev/null +++ b/board/sunxi/dram_r7dongle.c @@ -0,0 +1,31 @@ +/* this file is generated, don't edit it yourself */ + +#include +#include + +static struct dram_para dram_para = { + .clock = 384, + .type = 3, + .rank_num = 1, + .density = 2048, + .io_width = 8, + .bus_width = 32, + .cas = 9, + .zq = 123, + .odt_en = 0, + .size = 1024, + .tpr0 = 0x42d899b7, + .tpr1 = 0xa090, + .tpr2 = 0x22a00, + .tpr3 = 0, + .tpr4 = 0, + .tpr5 = 0, + .emr1 = 0x04, + .emr2 = 0x10, + .emr3 = 0, +}; + +unsigned long sunxi_dram_init(void) +{ + return dramc_init(&dram_para); +} -- cgit v1.2.1
