If I apply this patch, and then run:

make P5020DS_SDCARD_config
make u-boot.pbl

And then follow the instructions from the README:

2). Boot from SD/MMC
Write u-boot.pbl to SD/MMC from offset 0x1000.
=>tftp 100000 u-boot.pbl
=>mmcinfo
=>mmc write 100000 8 441
Change SW1[1:5] = off off on on off.

Will it work?

If I replace the word P5020DS with P3041DS, will it still work?

What I'm trying to figure out is whether rcw.cfg and pbi.cfg are truly
generic for all 3 systems this patch claims support for, or if I have
to replace them with different versions for those P* systems. My guess
is that the rcw.cfg needs to be changed, but I wanted to check. If it
needs to be changed, then what we need is something like
rcw_p5020ds.cfg, rcw_p4080ds.cfg, rcw_p3041.cfg.
