ENGR00163513 MX6Q-UBOOT : Add download_mode cmd
Add "download_mode" command to U-Boot. It will force a system reset and let boot running in "boot from serial rom" mode, which can be used by manufacturing tool. The command will triggle a write to SRC_GPR9 and SRC_GPR10, then triggle a watchdog reset. GPR9 and GPR10 can maintain their value during the reset, the value in it make ROM to start in "boot from serial rom" mode. After that GPR9 and GPR10 are written by their original value for normal boot. Signed-off-by: Eric Sun <jian.sun@freescale.com>
