2008-02-21Fix CPU POST test failureYuri Tikhonov
The CPU POST test code (run from cpu_post_exec_31()) doesn't follow the ABI carefully, at least the CR3, CR4, and CR5 fields of CR are clobbered by it. The gcc-4.2 with its more aggressive optimization exposes this fact. This patch just saves the CR value before running the test code, so allowing it to do anything it wants with CR.

2008-01-16ppc4xx: Refactor ECC POST for AMCC Denali coreLarry Johnson
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.

2008-01-14ppc_4xx: Fix post spr.c for PPC405Niklaus Giger
post/cpu/ppc4xx/spr.c contained a few checks for registers only present for PPC440 and derivates processor. Signed-off-by: Niklaus Giger <niklaus.giger@netstal.com>
2008-01-09POST: Execute SPR test after relocationStefan Roese
On LWMON5 we now use d-cache as init-ram and stack. The SPR POST test uses self modifying code and this doesn't work with stack in d-cache, since I can't move the code from d-cache to i-cache. We move the SPR test to be executed a little later, after relocation. Then stack is located in SDRAM and this self-modifying code is no problem anymore. Signed-off-by: Stefan Roese <sr@denx.de>

2007-12-27ppc4xx: Fix problem in 44x cache POST routineStefan Roese
As repoted by Larry Johnson, running "diag run cache" caused a crash in U-Boot. This problem was introduced by a patch that removed the TLB entry for the cache test after the test has completed. Since this TLB was only setup once, a 2nd attempt to run this cache test failed with a crash. Now this TLB entry is created every time the routine is called. Signed-off-by: Stefan Roese <sr@denx.de>

2007-12-27Fix/enhance ECC POST for 440EPx/GRxLarry Johnson
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>

2007-10-31ppc4xx: Enable CPU POST test for 4xx with dcache enabledStefan Roese
Now with caches enabled (i- and d-cache) on 44x, we need a chance to disable the cache for the CPU POST tests, since these tests consist of self modifying code. This is done via the new change_tlb() function. Signed-off-by: Stefan Roese <sr@denx.de>
2007-10-31ppc4xx: Change 4xx POST ethernet test to handle cached memory tooStefan Roese

2007-08-25POST: limit memory test area to not touch global data anymoreYuri Tikhonov
As experienced on lwmon5, on some boards the POST memory test can corrupt the global data buffer (bd). This patch fixes this issue by checking and limiting this area. Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Stefan Roese <sr@denx.de>

2007-08-14POST: Add option for external ethernet loopback testStefan Roese

2006-09-01Add support for a saving build objects in a separate directory.Marian Balakowicz
Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
