* ppc4xx/POST: Handle cached SDRAM correctly in Denali (440EPx) ECC POSTStefan Roese2010-11-28-0/+4
| | | | | | | | | | | This patch fixes a problem in the Denali (440EPx) SDRAM ECC POST test. When cache is enabled in the SDRAM area, the values written to SDRAM need to be flushed from cache to SDRAM using the dcfb instruction. Without this patch the POST ECC test failed. Now its working again on platforms with cache enabled in SDRAM. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese2010-09-23-1/+1
| | | | | | | | | This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Refactor ECC POST for AMCC Denali coreLarry Johnson2008-01-16-131/+135
| | | | | | | | | | | | | The ECC POST reported intermittent failures running after power-up on the Korat PPC440EPx board. Even when the test passed, the debugging output occasionally reported additional unexpected ECC errors. This refactoring has three main objectives: (1) minimize the code executed with ECC enabled during the tests, (2) add more checking of the results so any unexpected ECC errors would cause the test to fail, and (3) use synchronization (only) where required by the processor.

* Fix/enhance ECC POST for 440EPx/GRxLarry Johnson2007-12-27-45/+45
| | | | | | | | | This patch allows the ECC POST to be used for different boards with the PPC440 Denali SDRAM controller. Modifications include skipping the test if ECC is not enabled (as for non-ECC DIMMs) and adding synchronization to prevent timing errors. Signed-off-by: Larry Johnson <lrj@acm.org>
