But I can't make that match what U-Boot does. AFAICS, u-boot/arch/mips/lib/bootm.c doesn't care about 32 or 64 bit, and simply does:
U-Boot isn't the only firmware used with MIPS systems, and in fact it's quite a recent addition; e.g. DEC REX and SGI ARCS firmware goes back at least to 1990 and we continue supporting these systems. There's also CFE, PMON, YAMON, etc.
I know. That's what I'm trying to make us support :-)
We can't blindly assume that all those firmwares implement the exact same command line and environment protocol as U-Boot. Yamon obviously uses something similar enough. But what about the others?
As mentioned, we're currently failing to boot from Bootware because of the relaxed checking here. Something needs to be done about that.
