eb-flash on scu2/3 (doomsday) - verify failed at address 0x21000104 (0x1 != 0xffffffff)

[alexazon]

I observed this:

• Sometimes the first attempt to flash a SCU over PCIe will fail
• The second attempt will (always?) work
• Every attempt to flash over UDP will succeed

workaround: use eb-flash-secure

[alexazon]

• Use eb-flash-secure
• Our next major release will contain a new flash controller (ASMI)
