Squashed commit of the following:
configs/makerlisp: Update comments about use of serial console.
configs/makerlisp: Add LED support, remove vestiges of button support (the board has no user buttons). Add support for SPI-based MMC/SD card slot.
arch/z80/src/ez80: Fix some link problems.
libs/libc/syslog/lib_syslog.c: The ZDS-II toolchain does not declare va_coy in stdarg.h. I think that the use of va_copy in vsyslog() is no necessary.
configs/makerlisp: Initial configuration directories cloned from ez80f910200zco with little more than naming changes.

/* The D3 GREEN LED is driven by an eZ80 GPI/O pin. However, it has some
|
|
* additional properties:
|
|
*
|
|
* 1. On input, it will be '1' if the I/O expansion board is present.
|
|
* 2. Setting it to an output of '0' will generate a system reset.
|
|
* 3. Setting it to an output of '1' will not only illuminate the LED
|
|
* take the card out of reset and enable power to the SD card slot.
|
|
*
|
|
* As a consequence, the GREEN LED will not be illuminated if SD card
|
|
* support or SPI is disabled. The only effect of CONFIG_ARCH_LEDS is that
|
|
* the GREEN LED will turned off in the event of a crash.
