Armada 38x BootROM has a bug which cause that BootROM's standard output
-is turned off on UART when SPI-NOR contains valid boot image. Nevertheless
+is turned off on UART when default boot source location contains valid boot image. Nevertheless
BootROM's standard input and BootROM's terminal echo are active and working

to manually overwrite BootROM variables stored in SRAM which BootROM use
