RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC
Actually, with the MPMC3 the XPS_LL_TEMAC still can directly connect to the MPMC. You set one of the ports' type to SDMA and it instantiates what is similar to the old CDMAC.

RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC
The LL_TEMAC can be connected in two topologies. One connects the locallink directly to the SDMA port of the MPMC3. The other topology connects to a PLB46 bus using an XPS_LL_FIFO, which (most likely) connects to the plb bus port of the mpmc. The easiest way to decipher the connection pattern is to use Base System Builder in EDK to generate both topologies (which is determined by the 'use DMA' parameter when selecting the LL_TEMAC device. The Linux driver in git.xilinx.com supports both topologies.

RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC
Basically, git.xilinx.com has a tree with most of the xilinx-related support already integrated and ported forward to a current kernel. It also includes ongoing work to unify microblaze and powerpc device drivers through flat device trees. See: http://www.mail-archive.com/linuxppc-embedded@ozlabs.org/msg28690.html To use the git.xilinx.com tree you should *not* generate the driver code directly into the Linux tree. Instead, you should generate the driver code in a dummy directory and copy arch/ppc/platforms/4xx/xparameters_ml*.h into the kernel tree. The BSP generation process is designed older 2.6.10-era kernels and will not work with recent kernels.
