I just noticed this breaks i.MX23 support:

arch/arm/mach-mxs/iomux-imx.c: In function 'imx_gpio_mode':
arch/arm/mach-mxs/iomux-imx.c:131:2: warning: implicit declaration of function 'BK_PRESENT' [-Wimplicit-function-declaration]
arch/arm/mach-mxs/iomux-imx.c:133:3: warning: implicit declaration of function 'GET_BITKEEPER' [-Wimplicit-function-declaration]
arch/arm/mach-mxs/built-in.o: In function `imx_gpio_mode':

/home/sha/dude/barebox/barebox/arch/arm/mach-mxs/iomux-imx.c:133: undefined reference to `GET_BITKEEPER'

Care to send a fix for this? You can reproduce this using the
chumby_defconfig.
