Hello Uwe: Are these three patches ok? Do i need to do some change about them? thanks Huang Shijie > add gpmi support for imx23 and imx28. > > Signed-off-by: Huang Shijie <b32955@freescale.com> > --- > arch/arm/mach-mxs/Kconfig | 2 + > arch/arm/mach-mxs/include/mach/gpmi-nfc.h | 63 +++++++++++++++++++++++++++++ > 2 files changed, 65 insertions(+), 0 deletions(-) > create mode 100644 arch/arm/mach-mxs/include/mach/gpmi-nfc.h > > diff --git a/arch/arm/mach-mxs/Kconfig b/arch/arm/mach-mxs/Kconfig > index 4f6f174..8132f1a 100644 > --- a/arch/arm/mach-mxs/Kconfig > +++ b/arch/arm/mach-mxs/Kconfig > @@ -22,6 +22,7 @@ config MACH_MX23EVK > select SOC_IMX23 > select MXS_HAVE_AMBA_DUART > select MXS_HAVE_PLATFORM_AUART > + select MXS_HAVE_PLATFORM_GPMI_NFC > select MXS_HAVE_PLATFORM_MXSFB > default y > help > @@ -35,6 +36,7 @@ config MACH_MX28EVK > select MXS_HAVE_PLATFORM_AUART > select MXS_HAVE_PLATFORM_FEC > select MXS_HAVE_PLATFORM_FLEXCAN > + select MXS_HAVE_PLATFORM_GPMI_NFC > select MXS_HAVE_PLATFORM_MXSFB > select MXS_OCOTP > default y > diff --git a/arch/arm/mach-mxs/include/mach/gpmi-nfc.h b/arch/arm/mach-mxs/include/mach/gpmi-nfc.h > new file mode 100644 > index 0000000..5b736f5 > --- /dev/null > +++ b/arch/arm/mach-mxs/include/mach/gpmi-nfc.h > @@ -0,0 +1,63 @@ > +/* > + * Copyright (C) 2011 Freescale Semiconductor, Inc.
