In previous implementation, signal handling for SMP was incorrect.
Thus, for example, if an inter-CPU signal happened an incorret tcb
was signaled and caused ASSERT().

handling and signal handling on the same CPU.

disable LPC17 FDR when not used (second fix)
if a boot loader sets the fractional divider (FDR) the baud rate in
nuttx will be wrong (multiplied by this fraction).
This also has to be added to lpc17_lowputc.c
Unfortunately the constant used for shifting the bits was wrong in the header file, so it took some time to realize this...

disable LPC17 FDR when not used
* disable LPC17 FDR when not used
if a boot loader set the fractional divider (FDR) the baud rate in
nuttx will be wrong (multiplied by this fraction).
So if it is not used, it should be disabled.
LPC176x docs say:
"
DIVADDVAL Baud-rate generation pre-scaler divisor value.
If this field is 0, fractional baud-rate generator will
not impact the UARTn baudrate.
MULVAL Baud-rate pre-scaler multiplier value.
This field must be greater or equal 1 for UARTn to operate properly,
regardless of whether the fractional baud-rate generator is used or not.
"
So DIVADDVAL is set to 0 and MULVAL is set to 1.

* The existence of the network driver ioctl() method should depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former enables the method, the later enables a subset of possible driver IOCTLs. This change should be basically a no-operation. The affected ioctl methods only support those subset of driver IOCTLs selected by CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl method.
* net/tcp: Write buffering logic should not wait for a free buffer if the socket was opened non-blocking. Also, rename the TCP write buffering macros from WRB_* to TCPWB_* to make room in the namespace for write buffering with other protocols.
* net/udp: Remove some conditional logic that was true if there is only a single network device, but not true in the multi-device context.
* This commit adds an as-of-yet untested implemented of UDP write buffering.
Squashed commit of the following:
net/udp: Address most of the issues with UDP write buffering. There is a remaining issue with handling one network going down in a multi-network environment. None of this has been test but it is certainly ready for test. Hence, the feature is marked EXPERIMENTAL.
net/udp: Some baby steps toward a corrected write buffering design.
net/udp: Remove pesky write buffer macros.
Eliminate trailing space at the end of lines.
net/udp: A little more UDP write buffering logic. Still at least on big gaping hole in the design.
net/udp: Undefined CONFIG_NET_SENDTO_TIMEOUT.
net/udp: Crude, naive port of the TCP write buffering logic into UDP. This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
net/udp: Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.
* net/udp: In sendto(), return EHOSTUNREACH if if the network is down.
* net/udp: Resolves final design issues with UDP write buffering. 100% code complete but also 100% untested.
* net/udp and tcp: Yet another (cosmetic) change to UDP and TCP write buffer macro naming.
* net/udp: UDP write buffering is basically functional but needs a lot more verification.
* net/udp: Fix memory leak with UDP + write buffer is closed. Also update TODO and comments and refresh a configuration.
* Update some comments.
* drivers/mtd/at24xx.c: Correct page size for AT24C02 part.
* arch/arm/src/stm32: Make STM32 usable with an external RTC. drivers/timers/ds3231.c: Correct some debug statments.
* arch/arm/src/stm32/stm32_spi.c: Removed unnecessary (and incorrect) speed limitation
* arch/arm/src/stm32/stm32f40xxx_i2c.c: Correct some recent changes to STM32F4 I2C that broke poll mode of operation.
* configs/flipnclick-sam3x: Using JTAG (vs. Bossac) I was finally able to load code and verify the basic NSH configuration. Updated READMEs. Also switched to USART0 (vs UART0) for the serial console because I was not getting bi-directional communication on the VCOM.

lpc43/54 SDMMC: Wading through bits trying to make sense out of what is a event want interrupt which deal mostly with commands+responses and what is a data transfer event. DTO is the only wildcard. I think this clear now but DMA transfers will fail with CRC error.
