Le 30/08/2011 18:25, Jean-Christophe PLAGNIOL-VILLARD : > http://www.calao-systems.com Well, it is a bit short. Before submitting to at91-l2, I rephrase it to: "Add support for Calao USB-A9G20 boards. It will be integrated in existing support for board of same form factor using at91sam9260 or at91sam9263." > Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> > --- > arch/arm/mach-at91/Kconfig | 8 ++ > arch/arm/mach-at91/Makefile | 1 + > arch/arm/mach-at91/board-usb-a926x.c | 145 +++++++++++++++++++++++++------ > arch/arm/mach-at91/include/mach/timex.h | 5 + > 4 files changed, 133 insertions(+), 26 deletions(-) > > diff --git a/arch/arm/mach-at91/Kconfig b/arch/arm/mach-at91/Kconfig > index 2248467..e27d160 100644 > --- a/arch/arm/mach-at91/Kconfig > +++ b/arch/arm/mach-at91/Kconfig > @@ -381,6 +381,14 @@ config MACH_GSIA18S > This enables support for the GS_IA18_S board > produced by GeoSIG Ltd company.
