Now that there is a generic GPIO driver framework
remove GPIO register unified name space legacy support.

add an exception request/free api similar to the interrupt request/fre
api so people can utilize the free software based exceptions for their
own purposes

- allow people to select the feature that is unavailable to the kernel: NMI, JTAG, or CYCLES.
- change default NMI handler to simply dump hardware trace buffer.
- remove default NMI handler completely as calling into kernel code is not safe
move example handler to wiki so people dont haphazardly copy and paste this stuff thinking its safe

Add ability to expend the hardware trace buffer via a configurable
software buffer - so you can have lots of history when a crash occurs.
The interesting way we do printk in the traps.c confusese the checking
script

Fix CCLK and SCLK checks, combine all arch checks into one file
for maintance. Checkins that remove more lines than they add are always
good.

revise anomaly handling by basing things on the compiler not the kconfig defines,
so the header is stable and usable outside of the kernel. This also allows us to
move some code from preprocessing to compiling (gcc culls dead code)
which should help with code quality (readability, catch minor bugs, etc...).

Initialize the exception vectors early in the boot process, so that CPLB faults
can be handled when memory protection is enabled.

setup aliases for some core Core A MMRs to ease porting in cases

Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.

- Move cache initialization to C from assembly.
- Move anomaly workaround for writing [ID]MEM_CONTROL to assembly, so
that we don't have to mess around with .align directives in C source.
- Fix a bug where bfin_write_DMEM_CONTROL would write to IMEM_CONTROL
- Break out CPLB related code from kernel/setup.c into their own file.
- Don't define variables in header files, only declare them.
