Content-Type: text/plain; charset=ISO-8859-1; format=flowed List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , I've just started bringing Linux up on a Xilinx Virtex 4 FPGA with a PPC405 core. I'm using 2.6.15, and a crosstools-built toolchain from an x86 running Linux. The choice of kernel version was because crosstools identified it as a working combination and I can see no reason to choose anything different at the moment. I'm a bit confused about the difference between the ppc and powerpc architecture trees in the kernel. I've been using the ppc tree because that seems to have the requisite sources in it (I'm basing it on the ML300 code which seems to be the thing to do), and also because that was the only powerpc-related tree in earlier kernels. I can't seem to find any documentation as to where the powerpc tree appeared from and why. Can anyone confirm that I should still be using the ppc tree? Or even better, point me to some documentation regarding them both? Actually, while I'm at it, pointers to anything useful regarding the 2.6 kernel and the Virtex 4 would be helpful. I've found a reasonable amount of stuff myself, but as these things usually go I'll only find the best documentation after I've solved the problems myself and therefore know what I'm looking for!
