The DMA base registers are available in a global named "base_addr" for
every Blackfin variant. Give this a more descriptive name, and remove
duplicate tables from some drivers.

theres no need to declare ram{end,start,base} in the head.S files
when declaring them with the other memory related variables in setup.c
is so much simpler/nicer

- set default u-boot partition size to 256k
- modify the offset with the size change
- use mtd defines (append for offset and full for size)
where applicable rather than churning constants when we dont have to

Remove some sort of bloaty code, try to get these pin_req arrays built at compile-time
- move this static things to the blackfin board file
- add pin_req array to struct bfin5xx_spi_master
- tested on BF537/BF548 with SPI flash

Changes:
1. The baud for spi mmc defined in board file is not used by the old
spi driver. A slower value from spi framework is used instead. In latest
bug fixing, the correct baud is use which is too high for spi MMC card.
2. SPI is enabled only after DMA is started.
3. MMC detection IRQ is set to 55.

Remove <linux/usb_sl811.h> ... somehow this was recreated when
the Blackfin arch was merged, instead of using <linux/usb/sl811.h>
which is the correct header.

Print out debug info, as early as possible - even before the
kernel initializes the interrupt vectors. Now we can print out debug
messages almost anytime during the boot process.

rewrite our reboot code in C rather than assembly to be like
other architectures and to allow board maintainers to define

- 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.

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...).
