2007-09-07[PPC440SPe] Convert machine check exceptions handlingGrzegorz Bernacki
Convert using fixup mechanism to suppressing MCK for the duration of config read/write transaction: while fixups work fine with the case of a precise exception, we identified a major drawback with this approach when there's an imprecise case. In this scenario there is the following race condition: the fixup is (by design) set to catch the instruction following the one actually causing the exception; if an interrupt (e.g. decrementer) happens between those two instructions, the ISR code is executed before the fixup handler the machine check is no longer protected by the fixup handler as it appears as within the ISR code. In consequence the fixup approach is being phased out and replaced with explicit suppressing of MCK during a PCIe config read/write cycle. Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
2007-08-18lib_ppc: make board_add_ram_info weakKim Phillips
platforms wishing to display RAM diagnostics in addition to size, can do so, on one line, in their own board_add_ram_info() implementation. this consequently eliminates CONFIG_ADD_RAM_INFO. Thanks to Stefan for the hint. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

2007-08-02[ppc440SPe] Graceful recovery from machine check during PCIe configurationGrzegorz Bernacki
During config transactions on the PCIe bus an attempt to scan for a non-existent device can lead to a machine check exception with certain peripheral devices. In order to avoid crashing in such scenarios the instrumented versions of the config cycle read routines are introduced, so the exceptions fixups framework can gracefully recover.

2007-08-02[ppc4xx] Separate settings for PCIe bus numbering on 440SPe rev.ARafal Jaworowski
This brings back separate settings for PCIe bus numbers depending on chip revision, which got eliminated in 2b393b0f0af8402ef43b25c1968bfd29714ddffa commit. 440SPe rev. A does NOT work properly with the same settings as for the rev. B (no devices are seen on the bus during enumeration). Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

2007-07-16ppc4xx: Add remove_tlb() function to remove a mem area from TLB setupStefan Roese
The new function remove_tlb() can be used to remove the TLB's used to map a specific memory region. This is especially useful for the DDR(2) setup routines which configure the SDRAM area temporarily as a cached area (for speedup on auto-calibration and ECC generation) and later need this area uncached for normal usage.
