The CPCI405 supports switching the boot-cs between its 2 flash chips with the
DIP-switch 4. You could copy the current ppcboot version into the 2nd flash
chip as a fallback (please test it once).
Please make sure to use the "CPCI405" U-Boot make-target and _not_ CPCI4052
for a revision 1.x board. To be sure what version of the board you have,
please take a look at the FPGA. If it's a Spartan 05 then it's a revision 1.x
board, if it's a Spartan 2 15 it's a revision 2.x board.

I am pretty sure that the current versions of U-Boot work without problems on
the CPCI405 boards (even revision 1.x).
