The corresponding ticket has some info on the machine:

https://dev.archive.openwrt.org/ticket/4153.html

but it's not clear what taihu in QEMU is in the first place. The comment 
in ppc405_boards.c says it's an evaluation board so most likely the above 
one may have been designed based on this reference board. Some info on the 
eval board can be found here:

http://www.welcm.com/amccTaihu/amccTaihu.htm
https://datasheet.octopart.com/EV-460GT-KIT-03-AMCC-datasheet-11746697.pdf
https://happytrees.org/files/chips/datasheets/product_selector_guide--AMCC--PowerPC.pdf

I wonder what ref405ep was then, an earlier or later or different version?
