Try to reduce the boot time of LS1020,after check the application note of AN12537/AMF-ENT-T3135, but still beyond 1min,pls advise how to resolve the problem,TKs!

 Boot from IFC Nor, log in attached:

1. There still have 7.5S untill  go into uBoot after reset(Reset-->14:38:09:833:    U-Boot 2019.04+(V1.2.2-6deb913-dirty) (Dec 11 2020 - 14:05:50 +0800))

 2.Then need 3s, when uboot board_init_f  goto  board_init_r (14:38:10:210:    DRAM:  1 GiB-->14:38:13:239:    Using SERDES1 Protocol: 48 (0x30))

 3. That should be 5539mS, when uboot goto kernel,but do not know why still delay(14:38:19:475:    Starting kernel ...-->14:38:25:053:    [    0.000000] Booting Linux on physical CPU 0xf00)
