To enter the special mode, one needs to short cut two pads with e.g. screw driver. After power up the SPL will execute u-boot in which proper actions will be taken. It is worth noting that we do not alter envs (even the BOOT_FROM variable) and unconditionally go to recovery. Signed-off-by: Lukasz Majewski <lukma@denx.de>
