... Some code calls select() with all three sets empty, nfds zero, and a non-NULL timeout as a fairly portable way to sleep with subsecond precision.'

drivers/serial/uart_16550.c: Support 16550 auto hardware flow control

    drivers/serial/uart_16550.c:  Add configuration option CONFIG_16550_SUPRESS_INITIAL_CONFIG.  This is identical to the standard configuration in arch/Kconfig CONFIG_SUPPRESS_UART_CONFIG, but with scope of only the 16550 driver.

drivers/serial/uart_16550.c:  Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART.

    config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations.

    u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO

1ee6083de3 Squashed commit of the following: 
drivers/syslog:  Channel configuration.  Decouple SYSLOG_SERIAL_CONSOLE and ARCH_LOWPUTC.  Since some hardware can output log to the special debug channel not serial.

    drivers/syslog/vsyslog.c: Support pre-pending a prefix string to log output if enabled.  This very useful to identify which cpu send out the log in AMP SoC.

    drivers/syslog/vsyslog.c: Make timestamp output same as linux kernel.  It's very useful if NuttX syslog retarget to Linux syslog.

sched/wqueue:  Modify high priority work queue to support multiple threads.

    sched/wqueue and libs/libc/wqueue:  workqueues don't need set global data to zero since .bss is cleared automatically.  Removing this unnecessary initialization also avoids the loss the work items queued before initialization.

3bf96c8e7e net/arp: Improve arp_find() commit 9774d35010 to reduce the amount and frequency of data copies. 2018-08-25 07:12:21 -06:00

aa409f46ab Merged in david_s5/nuttx/master_kinetis_i2c_fix (pull request #711) 
kinetis:i2c ensure timeout on bus error

The code had a dead wait on I2C_S_BUSY. Noise on the
   bus would cause the driver to hang.

   Add timeout on invalid states of I2C_S_BUSY to allow
   the upper layers do deal with restart or abort.
