Android 控制fastboot模式下功能

涉及代碼如下

bootable/bootloader/lk/makefile

# 這裏編譯條件使得user版本下 fastboot 很多功能失效
ifeq ($(TARGET_BUILD_VARIANT),user)
  CFLAGS += -DDISABLE_FASTBOOT_CMDS=1
endif

bootable/bootloader/lk/app/aboot/aboot.c

// 這裏即是宏使用的地方，涉及如下指令是否能用
#ifndef DISABLE_FASTBOOT_CMDS
						/* Register the following commands only for non-user builds */

						{"erase:", cmd_erase},
