[U-Boot] [PATCH 1/3] ppc/85xx: Cleanup p1_p2_rdb PCI setup
by Kumar Gala 17 Sep '09

General code cleanup to use in/out IO accessors as well as making the code that prints out info sane between board and generic fsl pci code.

[U-Boot] Compile for SPARC Leon3 fails with *** No rule to make target ... ***
by Kraitschy, Tobias 17 Sep '09

17 Sep '09

Hi all, I`ve implemented Gaisler Research`s Leon3 SPARC core to a FPGA evaluation board of Actel. Now I`m about to get U-Boot running. So I made up my own board directory, added header files with my configuration-parameters etc. just as discribed in the u-boot README. The "make myboard_config" goes well, but "make all" fails with the following message. make[1]: *** No rule to make target `/u-boot-2009.08_build/cpu/leon3/start.S', needed by `/u-boot-2009.08_build/cpu/leon3/start.o'. Stop. I´d like to add that I set "BUILD_DIR=`/u-boot-2009.08_build" and I am using Gaisler`s Bare Cross Compiler with GCC 3.4.4. Searching the mailing-list-archives brought no advice to me. I also tried to study the Makefiles for half a week now, but I´m not familiar enought with it. Thanks for your help! Best regards, Tobias Kraitschy

[U-Boot] [PATCH] ppc4xx: Consolidate get_OPB_freq()
by Stefan Roese 17 Sep '09

17 Sep '09

All 4xx variants had their own, mostly identical get_OPB_freq() function. Some variants even only had the OPB frequency calculated in this routine and not supplied the sys_info.freqOPB variable correctly (e.g. 405EZ). This resulted in incorrect OPB values passed via the FDT to Linux. This patch now removes all those copies and only uses one function for all 4xx variants (except for IOP480 which doesn't have an OPB).
