Mike Frysinger 685a694f06 Blackfin: convert early_printk EVT init to a loop
The EVT registers are all contiguous in the memory map, so using a loop to
initialize them all rather than hardcoding the list results in much better
generated code (a hardware loop rather than a whole bunch of individual
loads).

Robin Getz b03b08ba9c [Blackfin] arch: Clean up dump_bfin_mem
Clean up dump_bfin_mem so that it will display
content from the kernel, as well as l1 instruction, when deferred
HW errors happen, print out the last frame info if it makes sense.

Robin Getz 337d390b3a Blackfin arch: Print out debug info, as early as possible
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.

Robin Getz 0ae53640b5 Blackfin arch: Initial patch to add earlyprintk support
This allows debugging of problems which happen eary in the kernel
boot process (after bootargs are parsed, but before serial subsystem
is fully initialized)
