powerpc/85xx: p1025twr: add module conditional to fix QE-uart issue

2015-06-03T02:37:29+00:00

A ioport setting was needed when used the QE uart function on TWR-P1025. Added a conditional definition to avoid missing this setting when the QE-uart driver was bulit to a module. Signed-off-by: Xie Xiaobo Signed-off-by: Li Pengbo Signed-off-by: Scott Wood

powerpc: mpc85xx: flush the l1 cache before cpu down in kexec

2015-06-03T02:37:28+00:00

We observe a "Zero PT_NOTE entries found" warning when vmcore_init() is running on the dump-capture kernel. Actually the PT_NOTE segments is not empty, but the entries generated by crash_save_cpu() are not flushed to the memory before we reset these cores. So we should flush the l1 cache as what we do in cpu hotplug. With this change, we can also kill the mpc85xx_smp_flush_dcache_kexec() since that becomes unnecessary. Please note: this only fix the issue on e500 core, we still need to implement the function to flush the l2 cache for the e500mc core. Fortunately we already had proposing patch for this support [1]. Hope we can fix this issue for e500mc after that merged. [1] https://lists.ozlabs.org/pipermail/linuxppc-dev/2014-March/115830.html Signed-off-by: Kevin Hao Signed-off-by: Scott Wood
