Given the fact that PPCBoot has been laid to rest, yes.
new at PPCBoot, but know about internals of ARMBoot. So I know the ROM and RAM versions of ARMBoot have to differ.
Ummm... you don;t need a "RAM version" at all.
Now, I plan to download PPCBoot into the RAM of a TQM850L via gdb and run from there. Gdb init the target processor inclusive address decoder. Can I load a ppcboot binary builded from plain tarball into the RAM or schould I swap some configs in include/configs/TQM850L.h ?
Why would you want to do this? U-Boot (and PPCBoot) is running perfectly fine from flash on all TQ boards. Why would you want to create a "RAM version"? It makes no sense to me.
As the CPU starts executing code from the boot device (CS0 = typically flash) this is the most natural mode to run PPCBoot, too. It was written to expect a CPU coming up from reset, so don't force it into any other environment without a good reason and a very good understanding of what you do, and why.
Since you ask this question, I think you should NOT try doing this.
