This is something that your boot loader needs to deal with. It has nothing to do with Linux as the Linux kernel does not care about such low-level hardware intializations. Strictly speaking, your message is off topic here. > I am using Wind River SBCPOWERQUICCII board. So I I'm pretty sure that this is not the official name of the board, or is it?

Usually this stuff is done in your boot loader. > Does ELDK have UPM initialization routines for my > purpose? Can I use this machine in a service then? Well, the ELDK includes the full source code of U-Boot, and yes, there is a configuration of U-Boot for the SBC8260 available. > Can I have this driver for any other Linux, for > example VxWorks BSP? Can I configure my driver and use > it for SRAM? First, this is not a driver. It is part of the low-level system initialization. Second, VxWorks is a proprietary operating system, and not "another Linux". Finally, you will have to check which boot loader you are using and which sort of initializations are already being done there for the SBC8260 board, and eventually add what might be missing for your specific setup. But this is off topic here (feel free to ask futher question on the u-boot-users mailing list - if you use U-Boot).
