I find this very useful and will need to do something similar soon if
you don't get to it first ;) I've already internally used some of your
old stuff I believe.

For us UBOOT_MACHINES = "P4008DS P4080DS_SPIFLASH P4080DS_SDCARD P4080DS_NAND"

Sometimes u-boot has different final output images, so maybe having
the machine.conf files do something like

UBOOT_OUTPUT["P4080DS_NAND"] = u-boot-nand.bin

So we can automagically have this work in the u-boot recipe.

I think upstream u-boot does not require this anymore.

I agree.

Seems fine either way to me, but I tend to think UBOOT_MACHINE could go away.

Are these using an old u-boot?
