The board I'm using (PPChameleonEVB) has 1 MB SRAM at 0xff800000. I've modified the .lds file and the flash base in include/configs so that "flash" is now taken to be the SRAM. (I know this is quick and dirty, not elegant. Also I know that the PPChameleonEVB has a jumper which swaps CS0# [flash] and CS1# [SRAM], but I don't have a BDI so I'm not able to load the SRAM.) Then I make an image file with
You can use the "old" copy of U-Boot to store the image to SRAM, then switch the jumper, the reset the board.
mkimage file, address 0xff800000 and entry point 0xff800100, TFTP it to the board and execute it. I obtain:

You would need to change so many things that a working "debugging version" gives no indication if a "real" version would run.
IMHO you are wasting your time.
Use the things as they are intended to be used: see above, or buy a BDI.
