ppc44x: Unification of virtex5 pp440 boards
This patch provides an unificated way of handling xilinx v5 ppc440 boards. It unificates 3 different things: 1) Source code A new board called ppc440-generic has been created. This board includes a generic tlb initialization (Maps the whole memory into virtual) and defines board_pre_init, checkboard, initdram and get_sys_info weakly, so, they can be replaced by specific functions. If a new board needs to redefine any of the previous functions (specific initialization) it can create a new directory with the specific initializations needed. (see the example ml507 board). 2) Configuration file Common configurations are located under configs/xilinx-ppc440.h, this header file interpretes the xparameters file generated by EDK and configurates u-boot in correspondence. Example: if there is a Temac, allows CMD_CONFIG_NET Specific configuration are located under specific configuration file. (see the example ml507 board) 3) Makefile Some work has been done in order to not duplicate work in the Main Makefile. Please see the attached code. In order to support new boards they can be implemented in the next way: a) Simple Generic Board (90% of the time) Using EDK generates a new xparameters.h file, replace ppc440-generic/xparameters.h and run make xilinx-ppc440-generic_config && make b) Simple Boards with special u-boot parameters (9 % of the time) Create a new file under configs for it (use ml507.h as example) and change your paramaters. Create a new Makefile paragraph and compile c) Complex boards (1% of the time) Create a new folder for the board, like the ml507 Finally, it adds support for the Avnet FX30T Evaluation board, following the new generic structure: Cheap board by Avnet for evaluating the Virtex5 FX technology. This patch adds support for: - UartLite - 16MB Flash - 64MB RAM Prior using U-boot in this board, read carefully the ERRATA by Avnet to solve some memory initialization issues.
