From: Heiko Schocher <[hs@denx.de]> Date: Mon, 22 Feb 2010 11:13:02 +0000 (+0530) Subject: arm: add support for the suen3 board from keymile X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=67fa8c25f5c2d23932c0f31b035281d6abbb0965;p=u-boot.git arm: add support for the suen3 board from keymile Add support for the ARM part of the mgcoge2, named suen3. This board is based on the Marvell Kirkwood (88F6281) SoC. As there come more board variants, common config options are collected in include/configs/km_arm.h. Also, this board use common code for all keymile boards, which is stored in board/keymile/common/common.c Signed-off-by: Holger Brunck Signed-off-by: Stefan Roese Signed-off-by: Heiko Schocher --- diff --git a/MAINTAINERS b/MAINTAINERS index d6f78de0ca..0340c19a68 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -413,9 +413,9 @@ Heiko Schocher muas3001 MPC8270 municse MPC5200 sc3 PPC405GP + suen3 ARM926EJS (Kirkwood SoC) uc101 MPC5200 - Peter De Schrijver ML2 PPC4xx diff --git a/MAKEALL b/MAKEALL index a8003101ab..19499853ac 100755 --- a/MAKEALL +++ b/MAKEALL @@ -587,6 +587,7 @@ LIST_ARM9=" \ spear310 \ spear320 \ spear600 \ + suen3 \ trab \ VCMA9 \ versatile \ diff --git a/Makefile b/Makefile index bd0151f5d0..ce77e10a00 100644 --- a/Makefile +++ b/Makefile @@ -3060,6 +3060,9 @@ spear320_config : unconfig spear600_config : unconfig @$(MKCONFIG) -n $@ -t $(@:_config=) spear6xx arm arm926ejs $(@:_config=) spear spear +suen3_config: unconfig + @$(MKCONFIG) $(@:_config=) arm arm926ejs km_arm keymile kirkwood + SX1_stdout_serial_config \ SX1_config: unconfig @mkdir -p $(obj)include diff --git a/board/keymile/common/common.c b/board/keymile/common/common.c index ec27bdae22..7b4eefd5c8 100644 --- a/board/keymile/common/common.c +++ b/board/keymile/common/common.c @@ -35,6 +35,7 @@ #include #endif +#include "../common/common.h" #if defined(CONFIG_HARD_I2C) || defined(CONFIG_SOFT_I2C) #include @@ -421,7 +422,6 @@ static int get_scl (void) return ((val & SCL_BIT) == SCL_BIT); } - #endif #if !defined(CONFIG_KMETER1) @@ -500,7 +500,7 @@ void i2c_init_board(void) out_8 (&dev->cr, (I2C_CR_MEN)); #else -#if defined(CONFIG_HARD_I2C) +#if defined(CONFIG_HARD_I2C) && !defined(CONFIG_MACH_SUEN3) volatile immap_t *immap = (immap_t *)CONFIG_SYS_IMMR ; volatile i2c8260_t *i2c = (i2c8260_t *)&immap->im_i2c; @@ -578,10 +578,12 @@ int fdt_get_node_and_value (void *blob, } #endif +#if !defined(CONFIG_MACH_SUEN3) int ethernet_present (void) { return (in_8((u8 *)CONFIG_SYS_PIGGY_BASE + CONFIG_SYS_SLOT_ID_OFF) & 0x80); } +#endif int board_eth_init (bd_t *bis) { diff --git a/board/keymile/km_arm/Makefile b/board/keymile/km_arm/Makefile new file mode 100644 index 0000000000..fffc6a3b7b --- /dev/null +++ b/board/keymile/km_arm/Makefile @@ -0,0 +1,51 @@ +# +# (C) Copyright 2009 +# Marvell Semiconductor +# Prafulla Wadaskar +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
