* arch/arm/src/lm, kinetis, lpc32, and nuc1xx: Add kernel build
support to all ARMv7-M and ARMv6-M chips. There are no
configurations in place to to verify these additions!
(2013-03-24).
* arch/arm/src/lm/lm_gpio.h: Correct typos in alternate function
definitions (2013-03-23).
* arch/arm/src/lm/lm_lowputc.c and lm_serial.c: Add support for
the 7 UARTs on the LM4F120 (2013-03-23).

Serial Console
^^^^^^^^^^^^^^
By default, all configurations use UART0 which connects to the USB VCOM
on the DEBUG port on the LM4F120 LaunchPad:
UART0 RX - PA.0
UART0 TX - PA.1
However, if you use an external RS232 driver, then other options are
available. UART1 has option pin settings and flow control capabilities
that are not available with the other UARTS::
UART1 RX - PB.0 or PC.4 (Need disambiguation in board.h)
UART1 TX - PB.1 or PC.5 (" " " " "" " ")
UART1_RTS - PF.0 or PC.4
UART1_CTS - PF.1 or PC.5
NOTE: board.h currently selects PB.0, PB.1, PF.0 and PF.1 for UART1, but
that can be changed by editting board.h
UART2-5, 7 are also available, UART2 is not recommended because it shares
some pin usage with USB device mode. UART6 is not available because its
only RX/TX pin options are dedicated to USB support.
UART2 RX - PD.6
UART2 TX - PD.7 (Also used for USB VBUS detection)
UART3 RX - PC.6
UART3 TX - PC.7
UART4 RX - PC.4
UART4 TX - PC.5
UART5 RX - PE.4
UART5 TX - PE.5
UART6 RX - PD.4, Not available. Dedicated for USB_DM
UART6 TX - PD.5, Not available. Dedicated for USB_DP
UART7 RX - PE.0
UART7 TX - PE.1
