Hi Stefan,

this is just where it was before.
But looking at the prompt
   SoC:   MV88F6820-A0 at 1600 MHz
   DRAM:  2 GiB (800 MHz, 32-bit, 2T, ECC not enabled)
   Disabling MCU watchdog... disabled
   WDT:   Started with servicing (60s timeout)

it looks like U-Boot's watchdog is being enabled after MCU watchdog.
It would be better to enable U-Boot's WDT before disabling MCU watchdog.
I will send another patch that moves it to another function,
board_late_init for example.

Shall I resend this series with this new patch?
