We need a FAT partition
Why are all of them (I mean vendor supplied U-boot) so in love with FAT? There is support of ext2 in U-boot, and they boot nothing but Linux.
Yeah, can't we do the RPi model with binary blobs (FAT) + /boot (ext2) + / (ext4)?
Hm? You and Marcus already did that for the RPi looong time ago. :)
For the Parallella the issue is that downstream U-Boot is on flash, and I don't want to brick the board I had to wait for so long with U-Boot upstreaming experiments of my own. (There's no direct JTAG connector.)
I could try to change my local boot environment, but then a JeOS image would not be of general use. By default, it tries to boot uImage + devicetree.dtb without looking for a boot.scr even. So unless we can chainload another U-Boot as "uImage" via bootm command with a dummy devicetree.dtb, we can't move the kernel to another partition nor fatload-incompatible filesystem.
Does that u-boot support ext2? If so, I think it's reasonable to have people do
# setenv bootcmd <foo> # saveenv
before they can run openSUSE on their boards :). And in that setenv that we write into the wiki we would make it search for boot.scr on ext2.
Well, it boils down to: Is it reasonable to expect that every openSUSE user of the board has a matching UART TTL adapter? On other boards that's been optional, in case everything Just Works(tm). You just stick our card in and you're good.
Just trying to be creative to make everyone's life easier ;).
If we no longer want to support original flashed firmware, then surely there's some simplifications we can start making in the JeOS sources.
Well, we still want the original firmware. The only thing I would consider ok for mandatory modification is the config. But I don't really have a strong opinion either way, whatever gets you there fastest and makes life reasonably easy for others is a win IMHO :).
