This may not be the "better, more generic solution", but I just added a CONFIG_CHIP_11_ERRATA option and code in lib_ppc/board.c to trim off only 256 bytes before the optional log buffer is carved out.
OK. I'll submit a similar patch in a short while. Please give it a try and let me know if you see problems with it.
There's a kernel patch for this errata that trims the memory length. If that patch is applied, does the kernel still need to be made to understand the changed logbuffer location?
I don't think so. With my next patch it should not be necessary anymore. With one exception: Linux kernel ports that have fixed memory sizes or calculate the memory size from the SDRAM controller setup (as done in some arch/powerpc kernels with bootwrapper support).
