---------------------------
What: Support for NEC DDB5476 evaluation boards.
When: June 2006
Why: Board specific code doesn't build anymore since ~2.6.0 and no
users have complained indicating there is no more need for these
boards. This should really be considered a last call.
Who: Ralf Baechle <ralf@linux-mips.org>
---------------------------
What: USB driver API moves to EXPORT_SYMBOL_GPL
When: Febuary 2008
Files: include/linux/usb.h, drivers/usb/core/driver.c

This enables support for the R5432-based NEC DDB Vrc-5476
evaluation board.
Features : kernel debugging, serial terminal, NFS root fs, on-board
ether port USB, AC97, PCI, PCI VGA card & framebuffer console,
IDE controller, PS2 keyboard, PS2 mouse, etc.
