From fe04b1121511a97982a1fcdd38e44d2029304a6d Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Thu, 8 Apr 2010 00:38:22 -0500 Subject: powerpc/e500mc: Implement machine check handler. Most of the MSCR bit assigments are different in e500mc versus e500, and they are now write-one-to-clear. Some e500mc machine check conditions are made recoverable (as long as they aren't stuck on), most notably L1 instruction cache parity errors.

The code should be relatively easy to modify to support 44x BookEs as well, but since I don't have any 44x to test, let's confine the code to FSL BookE. (The only FSL-specific part so far is 'flush_dcache_L1'.)

During this procedure a small 4KiB mapping is created and after that one a 64MiB. Currently the offset of the 4KiB page in that we run is zero because the complete startup up code is in first page which starts at RPN zero. If the code is recycled and moved to another location then its execution will fail because the start address in 64 MiB mapping is computed wrongly. It does not consider the offset to the page from the begin of the memory. This patch fixes this. Usually (system boot) r25 is zero so this does not change anything unless the code is recycled.

The code borrows the initial MMU-setup code to create the identical mapping mapping. The only difference to the original boot code is the size of the mapping(s) and the executeable address. The kexec code maps the first 2 GiB of memory in 256 MiB steps. This should work also on e500v1 boxes. SMP support is still not available.
