i ask since i glanced at it and it clearly doesn't reference the "gpio" command:

... snip ... #define CONFIG_CMD_FLASH /* flinfo, erase, protect */ #define CONFIG_CMD_FPGA /* FPGA configuration Support */ #define CONFIG_CMD_GETTIME /* Get time since boot */ #define CONFIG_CMD_HASH /* calculate hash / digest */ #define CONFIG_CMD_HWFLOW /* RTS/CTS hw flow control */ ... snip ...

i didn't look any further, just thought i'd ask about that first.
