devices that have USB, but no serial port.
* arch/mips/src/pic32mx/pic32mx_spi.c: Add a PIC32 SPI driver. Initial
checkin is primitive, incomplete (lacks interrupt logic), and untested.
* configs/pic32-startkit/nsh: Completed verification of the PIC32 Ethernet
Starter Kit port. Added and verified the NuttShell (NSH) on the PIC32
Ethernet Starter Kit. I can now (finally) claim to have complete the
basic port to this board.

# CONFIG_FS_FAT - Enable FAT filesystem support

# CONFIG_FAT_LFN - Enable FAT long file names. NOTE: Microsoft claims
# patents on FAT long file name technology. Please read the
# disclaimer in the top-level COPYING file and only enable this
# feature if you understand these issues.
# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the
# default, maximum long file name is 255 bytes. This can eat up
# a lot of memory (especially stack space). If you are willing
# to live with some non-standard, short long file names, then
# define this value. A good choice would be the same value as
# selected for CONFIG_NAME_MAX which will limit the visibility
# of longer file names anyway.
# CONFIG_FS_NXFFS: Enable NuttX FLASH file system (NXFF) support.
# CONFIG_NXFFS_ERASEDSTATE: The erased state of FLASH.
# This must have one of the values of 0xff or 0x00.

# CONFIG_NXFFS_PACKTHRESHOLD: When packing flash file data,
# don't both with file chunks smaller than this number of data bytes.
# CONFIG_NXFFS_MAXNAMLEN: The maximum size of an NXFFS file name.
# Default: 255.
# CONFIG_NXFFS_PACKTHRESHOLD: When packing flash file data,
# don't both with file chunks smaller than this number of data bytes.
# Default: 32.
# CONFIG_NXFFS_TAILTHRESHOLD: clean-up can either mean
# packing files together toward the end of the file or, if file are
# deleted at the end of the file, clean up can simply mean erasing
# the end of FLASH memory so that it can be re-used again. However,
# doing this can also harm the life of the FLASH part because it can
# mean that the tail end of the FLASH is re-used too often. This
# threshold determines if/when it is worth erased the tail end of FLASH
# and making it available for re-use (and possible over-wear).
# Default: 8192.
# CONFIG_FS_ROMFS - Enable ROMFS filesystem support
# CONFIG_FS_RAMMAP - For file systems that do not support XIP, this
# option will enable a limited form of memory mapping that is
