Could you give some link giving details of the board please. > >The IGEP v2 board is a low-cost, fan-less and industrial temperature >range single board computer that unleashes laptop-like performance and >expandability without the bulk, expense, or noise of typical desktop >machines. Its architecture shares much in common with other OMAP3 boards. > >Signed-off-by: Enric Balletbo i Serra <eballetbo@xxxxxxxxxxx> >--- > arch/arm/mach-omap2/Kconfig | 4 + > arch/arm/mach-omap2/Makefile | 2 + > arch/arm/mach-omap2/board-igep0020.c | 252 ++++++++++++++++++++++++++++++++++ > 3 files changed, 258 insertions(+), 0 deletions(-) > create mode 100644 arch/arm/mach-omap2/board-igep0020.c > >diff --git a/arch/arm/mach-omap2/Kconfig b/arch/arm/mach-omap2/Kconfig >index 75b1c7e..9936510 100644 >--- a/arch/arm/mach-omap2/Kconfig >+++ b/arch/arm/mach-omap2/Kconfig >@@ -85,6 +85,10 @@ config MACH_OMAP_ZOOM2 > bool "OMAP3 Zoom2 board" > depends on ARCH_OMAP3 && ARCH_OMAP34XX > >+config MACH_IGEP0020 >+ bool "IGEP0020" >+ depends on ARCH_OMAP3 && ARCH_OMAP34XX >+ > config MACH_OMAP_4430SDP > bool "OMAP 4430 SDP board" > depends on ARCH_OMAP4 >diff --git a/arch/arm/mach-omap2/Makefile b/arch/arm/mach-omap2/Makefile >index 6b7702f..df0bdc4 100644 >--- a/arch/arm/mach-omap2/Makefile >+++ b/arch/arm/mach-omap2/Makefile >@@ -74,6 +74,8 @@ obj-$(CONFIG_MACH_NOKIA_RX51) += board-rx51.o \ > obj-$(CONFIG_MACH_OMAP_ZOOM2) += board-zoom2.o \ > mmc-twl4030.o \ > board-zoom-debugboard.o >+obj-$(CONFIG_MACH_IGEP0020) += board-igep0020.o \ >+ mmc-twl4030.o \ > > obj-$(CONFIG_MACH_OMAP_4430SDP) += board-4430sdp.o > >diff --git a/arch/arm/mach-omap2/board-igep0020.c >b/arch/arm/mach-omap2/board-igep0020.c >new file mode 100644 >index 0000000..15175e0 >--- /dev/null >+++ b/arch/arm/mach-omap2/board-igep0020.c >@@ -0,0 +1,252 @@ >+/* >+ * Copyright (C) 2009 Integration Software and Electronic Engineering. >+ * >+ * Modified from mach-omap2/board-generic.c >+ * >+ * This program is free software;
