On new LS1021ATWR board, U-boot can start up on NOR bank0. With jump setting(Bank select, UART select) change to bank1 setting, it can start up u-boot on bank1 after power cycle.
I noticed there is "bank-switch" command I supposed it was intend to switch from bank 0 to bank 1 without power cycle.
I did this test, enter Bank 0 u-boot, then enter "bank_switch 1" to attempted to switch bank from 0 to 1 without power power cycle, but it seems not be as I expected.
I don't know what the "bank_switch n" command use senario, could you please intruduce how to use this command?
