In 3.7 (where that original config file came from), ARCH_MXS did NOT depend on

enable ARCH_MXS.
I had to add the following to my config:
CONFIG_ARCH_MULTI_V5=y
CONFIG_ARCH_MULTI_V6_V7=n
CONFIG_ARCH_MULTI_V7=n
With these three lines "make oldconfig" seemed to no longer kill
important config entries.
"make uImage" failed. I got asked to specify a "LOADADDR" so I created
my image like this:
LOADADDR=0x40008000 make uImage
But the resulting kernel fails to boot. The error message makes sense.
Maybe a bug in imx23.dtsi? In fact the serial port "duart:
serial@80070000" does not have a "dma-names" property:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/imx23.dtsi#n496
But is this a blocker and can cause the kernel boot to stop?
