I tried to add following patch for new resources, but now it fails with:
[ 141.534545] pxa2xx-ir pxa2xx-ir: can't request region for resource [mem 0x40700000-0x40700100]
[ 141.534574] pxa2xx-ir pxa2xx-ir: resource stuart not defined
[ 141.534656] pxa2xx-ir: probe of pxa2xx-ir failed with error -16
That's because STUART is allocated by normal UART driver at:
http://lxr.free-electrons.com/source/arch/arm/mach-pxa/devices.c#L244
So somehow there must be configuration for STUART used with FICP and STUART alone (probably can be used for normal UART).
