* arch/arm/src/lpc17xx/lpc17_ssp.c -- Fix compilation errors when SSP1 is
selected.
* configs/olimex-lpc1766stk/nsh -- Enable network and SD/MMC card support in
NSH (not verified on initial check-in)
NSH. Networking and telnetd interface functional. Still testing SPI-based
SD/MMC.
* examples/nsh/nsh_netinit.c -- Fix NSH bug. If CONFIG_NET is selected, but
CONFIG_EXAMPLES_NSH_TELNETD is not selected, then the network is never
initialized and bad things happen if you try to ping.
