[U-Boot-Users] porting u-boot
I'm still into porting u-boot to a full-custom board. The u-boot README says that the u-boot will scan for my SDRAM and find out how much I have. I suppose that will only work if I write a custom SDRAM-setup-procedure ..../u-boot/board/CUSTOMBOARD/customboard.c ? Is that right?
If so, is there any documentation about what needs to be done there? I believe that the sdram_table array used in all those board_name.c files contains hexadecimal encoded instructions programming the UPM.. am I right?
Well... any hints (like, for example, "RTFM manual/ressource name") are welcome.

You cannot avoid this, right (you need it even if you set up for a fixed memory size only).

Sure. See the processor's User's manual and related documentation.

Here we go: RTFM the processor documentation and related material ;-)
