fbb6f6cde0 configs/: Rename ZDS-II start files from xxx_lowinit.c to xxx_boot.c; rename board initialization logic from xxx_lowinit() to xxx_board_initialize(). These changes make the ZDS-II configurations more similar to board initialization conventions to used for other architectures. 2019-06-05 10:14:58 -06:00

cf8268f7d8 configs/makerlisp/src/ez80_lowinit.c: Remove redundant SPI GPIO setup. This is already done in the SPI driver. 
configs/makerlisp/src/ez80_spi.c:  Add hooks needed by SPI driver.  Move SPI MMC/SD chip selected configuration from ez80_lowinit.c to here as it done in other NuttX architectures.  This enables support for multiple devices on the SPI bus.

4e98980045 Add initial support for the MakerLisp eZ80 board. Ref: https://makerlisp.com/ 
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.
