* ppc4xx: Fix compilation error on ML2 boardStefan Roese2010-02-03-0/+1
| | | | | | | | | | | | | | | Recently this compilation error occurs: Configuring for ML2 board... traps.c: In function 'MachineCheckException': traps.c:159: error: 'debugger_exception_handler' undeclared (first use in this function) traps.c:159: error: (Each undeclared identifier is reported only once traps.c:159: error: for each function it appears in.) This patch now fixes it by including kgdb.h Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Fix printf format warnings now visible with the updated format checkStefan Roese2008-07-10-13/+13
| | | | | | | | | This patch fixes ppc4xx related printf format warning. Those warnings are now visible since patch dc4b0b38d4aadf08826f6c31270f1eecd27964fd [Fix printf errors.] by Andrew Klossner has been applied. Thanks, this is really helpful. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 1 of 2): * Rolls up a suite of changes to enable correct primordial stack and global data handling when the data cache is used for such a purpose for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS). * Related to the first, unifies DDR2 SDRAM and ECC initialization by eliminating redundant ECC initialization implementations and moving redundant SDRAM initialization out of board code into shared 4xx code. * Enables MCSR visibility on the 405EX(r). * Enables the use of the data cache for initial RAM on both AMCC's Kilauea and Makalu and removes a redundant CFG_POST_MEMORY flag from each board's CONFIG_POST value. - Removed, per Stefan Roese's request, defunct memory.c file for Makalu and rolled sdram_init from it into makalu.c. With respect to the 4xx DDR initialization and ECC unification, there is certainly more work that can and should be done (file renaming, etc.). However, that can be handled at a later date on a second or third pass. As it stands, this patch moves things forward in an incremental yet positive way for those platforms that utilize this code and the features associated with it.

* [PPC440SPe] Convert machine check exceptions handlingGrzegorz Bernacki2007-09-07-6/+0
| | | | | | | | | | | | | | | | 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>

* | [ppc440SPe] Graceful recovery from machine check during PCIe configurationGrzegorz Bernacki2007-08-02-3/+8
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | This patch prints the DDR status registers upon machine check interrupt on the 440EPx/GRx. This can be useful especially when ECC support is enabled.

| | | | | | | | | | | | | | | | | | | | | | - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com> Signed-off-by: Stefan Roese <sr@denx.de>
