The 405 machine are still close to deprecation I think. We are still
struggling to boot one with mainline Linux, using uboot provided by
Thomas which skips SDRAM init. It is not clear to me if u-boot is
strictly necessary. It depends if Linux relies on it to do some
pre-initialization of HW. I guess once we find a good DTS for it, or
not, we can take a decision.
FWIW, seems like this tarball contains a dts for a "taihushui" 405ep board:

... I wonder whether that's the same board as the "taihu" board in QEMU?
The corresponding ticket has some info on the machine:

Ok, so as far as I got that now, Taihu was a board by AMCC, while Taihushui
was from Tranzeo ? ... so they were likely different boards, I think.
I wonder what ref405ep was then, an earlier or later or different version?
According to hw/ppc/ppc405_boards.c, the ref405ep machine was a reference
board by IBM, not from AMCC ?
