8bc90a1899 This adds basic architectural support for the LPC546xx family and includes support for the LPCXpresso-LPC54628 board. The basic NSH port is almost complete... still lacking GPIO support and LED support. There are still no significant drivers available.
Squashed commit of the following:

    arch/arm/src/lpc54xx:  Finish off some missing logic.  Complete now execpt for GPIO and LED support.
    arch/arm/src/lpc54xx:  Add lpc54_clrpend.c
    arch/arm/src/lpc54xx:  Serial driver is complete and compiles.
    arch/arm/src/lpc54xx:  Add beginning of a serial driver (still missing some logic)
    arch/arm/src/lpc54xx:  Fleshes out low level USART intialization.

    arch/arm/src/lpc54xx:  Beginning of PLL configuration logic.
    arch/arm/src/lpc54xx:  Fix a few things from first compile attempt.  Compilation cannot work until I at least finish the clock configuration logic.
    arch/arm/src/lpc54xx: Addes some SysTick logic.
    arch/arm/src/lpc54xx:  Completes basic startup logic (sans clock configuration) and interrupt configuration.
     arch/arm/src/lpc54xx:  Add generic ARMv7-M start-up logic (needs LPC54628 customizations); add emtpy file that will eventually hold the clock configuration logic.

Subject: [PATCH] drivers/pipes: poll: fix off-by-one error in calculation of bytes in the buffer

Buffer calculation in pipe poll setup is off-by-one when read indexis larger than write index. This causes poll() not getting POLLINwhen buffer has one byte as calculation gives zero bytes in buffer.

Reproducible with:

  {
    char buf[8] = { 0, };
    int fds[2];
    struct pollfd in_pfd;

    pipe2(fds, 8);

    write(fds[1], buf, 7);
    read(fds[0], buf, 7);
    write(fds[1], buf, 1);

    in_pfd.fd = fds[0];
    in_pfd.events = POLLIN;
    ret = poll(&in_pfd, 1, -1); // pipe bug => stuck waiting
    assert(ret == 1);
  }
