Ensure that the remaining callers of read_cpuid_ext can't attempt an
extended CP15 register read on ARMv6 cores that don't support it. The
only one that appears dodgy is tlb_ops_need_broadcast().
While here, convert feat_v6_fixup() to use cpu_is_arm1136_r0() to save
a few lines of code.

Hi!
I'd like to convert Nokia N900 to device tree.
Unfortunately, serial port is not easily available (very special cable
would be needed, does someone know where to get one?)
One way to get one is building it yourself. I finished mine yesterday:

Auto request GPIO as an input line when used as IRQ line for DT case has been

Hello,
Being the author of these patches I'm ashamed that they are causing a
regression. I did my best to make sure that it would work on OMAP1 and
OMAP2+ platforms booting with both legacy board files and DT.
Also, I didn't come with this solution in a vacuum. This was deeply
