I agree that this could be much more configurable. Apparently no one has needed those options yet, as there currenntly isn't any code to reconfigure the clocks at all. I would guess most people are using an EEPROM to set things up. As for shortsightedness, keep in mind that I'm not a full time U-Boot developer. I solved a problem to get our board working and I'm happy to share the solution I came up with, but I just don't have the resources to solve a problem that someone else might have later. IMO, with the basics in this patch, it should be easy enough for anyone to modify it for additional configurations if they are needed. Mike

[U-Boot-Users] [PATCH] TQM5200: fix bug in SDRAM initialization code
by Martin Krause 25 Feb '08

25 Feb '08

This patch fixes a bug in the SDRAM initialization code for the TQM5200. The hi_addr bit is now set correctly. Without this patch the hi_addr bit is always set to 1, if the second flash bank is not populated. For other MPC5200 boards a correspondig patch has already been applied some time ago, see commit a63109281ad41b0fb489fdcb901171f76bcdbc2c.
