Rethinking some NAND interfaces
LPC3131 EHCI:  Add USB host tracing support
Olimex LPC_H3131:  Add GPIO support for LEDs and for USB host power enable and overcurrent detection.
Olimex LPC-H3131: Drop loops-per-second by a factor of 4. Why is the H3131 only 25% as fast as the EA3131 at the same clocking?
SAMA5 NAND:  Add block erase logic
ARM9:  More cache control functions
lpc31 ECHI.  Early debug changes
Olimex LPC-H3131:  Some restructuring of intialization logic
LPC-H3131:  SDRAM support (untested)
SAMA5 NAND:  More progress
LPC-H3131 SDRAM: Fix some build issues
LPC-H3131: SDRAM timing update.  Still does not work
LPC-H3131: SDRAM comments updated
LPC3131 EHCI: More fixes
LPC31xx EHCI: Power power changes
SAMA5 NAND:  More stuff
Cosmetic changes
