* 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>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese2010-10-04-280/+22
| | | | | | | | | | | | | | | | | This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | 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: POST UART: Use in/out_8() io-accessor functionsStefan Roese2010-09-23-64/+41
|/ | | | | | | | | | | | | | This patch fixes a problem in the PPC4xx POST UART driver. This driver incorrectly used the in/out8() io-accessor functions. This could lead to problems since these functions don't guarantee execution ordering. This patch now replaces these functions with the correct ones. Additionally the driver is converted to using the NS16550 struct instead of macros for the register offsets. And some common code is factored out for better maintainability.

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-1/+1
| | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-36/+36
| | | | | | | | | | | | | | | | This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. 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.

* ppc4xx: Fix problem in 44x cache POST routineStefan Roese2007-12-27-22/+19
| | | | | | | | | | | 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>
