2011-04-30Handle most LDSCRIPT setting centrallyScott Wood
Currently, some linker scripts are found by common code in config.mk. Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is sometimes in arch config.mk and sometimes in board config.mk. Some are found using an arch-specific rule for looking in CPUDIR, etc. Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds. Replace all of this -- except for a handful of boards that are actually selecting a linker script in a unique way -- with centralized ldscript finding. If board code specifies LDSCRIPT, that will be used. Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used. If neither of these are specified, then the central config.mk will check for the existence of the following, in order: $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds $(TOPDIR)/$(CPUDIR)/u-boot.lds Some boards (sc3, cm5200, munices) provided their own u-boot.lds that were dead code, because they were overridden by a CPUDIR u-boot.lds under the old powerpc rules. These boards' own u-boot.lds have bitrotted and no longer work -- these lds files have been removed. Signed-off-by: Scott Wood <scottwood@freescale.com> Tested-by: Graeme Russ <graeme.russ@gmail.com>
2010-10-18Makefile: move all Power Architecture boards into boards.cfgWolfgang Denk
Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice. Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-09-09ppc4xx: ppc440-generic-ALL: Fix out of tree build v2Ricardo Ribalda Delgado
This patch solves the problems compiling ml507, v5fx30teval and ppc440-generic out of tree. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es>
2008-09-05ppc44x: Unification of virtex5 pp440 boardsRicardo Ribalda Delgado
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.
