From Onur:

fyi.

Probably there are more options for accessing nor flash on ML401. But I created an ACE file, with microblaze hardware, u-boot and milkymist bios. When you use this file to configure your board. When you boot you will see u-boot command prompt. Current version of milkymist bios binary is located on 0x8c000000 address. (we can also use tftp to load another binary) To burn milkymist image to nor flash, see log below.
