On Marvell hardware, you can send a different U-Boot using the serial port, even if the on-flash U-Boot is broken. Have a look at tools/kwboot.c in the mainline U-Boot sources. It uses the serial port to send using the Xmodem protocol, a new U-Boot payload to the Kirkwood SoC.
Depends on the SoC. I am the proud owner of a Wireless Space which, due its Kirkwood SoC's revision, cannot recover through UART even though kirkwoods normally can. Not to mention my ED Mini V2, which has orion, with no UART recovery at all.
I did not find if MV88F1155 has UART recovery.
Also, UART recovery requires having a working U-boot image file. JPT, do you have a working (pristine) U-Boot for your ReadyNAS, or can you get one from Netgear?
Best regards,
Thomas
Amicalement,
