[U-Boot-Users] [PATCH 2/2 V2] qemu-mips: add full functionnalty and support of CONFIG_SMALLEST

[Jean-Christophe PLAGNIOL-VILLARD]

add support of :
#define CONFIG_CMD_ASKENV
#define CONFIG_CMD_LOADS
#define CONFIG_CMD_LOADB
#define CONFIG_CMD_PING
#define CONFIG_CMD_CDP
#define CONFIG_CMD_SAVES
#define CONFIG_CMD_SETEXPR
