2011-01-198xxx/ddr: add support to only compute the ddr sdram sizeHaiying Wang
This patch adds fsl_ddr_sdram_size to only calculate the ddr sdram size, in case that the DDR SDRAM is initialized in the 2nd stage uboot and should not be intialized again in the final stage uboot.

2011-01-14powerpc/85xx: Add the workaround for erratum ELBC-A001 (enable on P4080)Kumar Gala
Simultaneous FCM and GPCM or UPM operation may erroneously trigger bus monitor timeout. Set timeout to maximum to avoid. Based on a patch from Lan Chunhe <b25806@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-01-14powerpc/8xxx: Move fsl_is_spd() into generic 8xxx ddr codeKumar Gala
Move the parsing of hwconfig to determine if to use spd into common code so we can share it across all boards instead of duplicating it everywhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-01-14powerpc/8xxx: Refactor SRIO initialization into common codeKumar Gala
Moved the SRIO init out of corenet_ds and into common code for 8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe controllers for SRIO. We utilize the fact that SRIO is over serdes to determine if its configured or not and thus can setup the LAWs needed for it dynamically. We additionally update the device tree (to remove the SRIO nodes) if the board doesn't have SRIO enabled. Introduced the following standard defines for board config.h: CONFIG_SYS_SRIO - Chip has SRIO or not CONFIG_SRIO1 - Board has SRIO 1 port available CONFIG_SRIO2 - Board has SRIO 2 port available (where 'n' is the port #) CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup) CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup) [ These mimic what we have for PCI and PCIe controllers ] Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Wolfgang Denk <wd@denx.de>
2011-01-14MPC8xxx DDR: align informational printsBecky Bruce
Add spaces to cause the informational prints to line up with the ones from init_func_ram() in board.c. Output now looks like this: .... DRAM: Detected 4096 MB of memory This U-Boot only supports < 4G of DDR You could rebuild it with CONFIG_PHYS_64BIT DDR: 2 GiB (DDR2, 64-bit, CL=5, ECC off) .... The prints from lbc_sdram_init() have also been modified to line line up and changed to start with "LBC SDRAM" instead of the confusing "SDRAM".

2011-01-14mpc85xx boards: initdram() cleanup/bugfixBecky Bruce
Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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>

2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

2010-05-12Enabled support for Rev 1.3 SPD for DDR2 DIMMsYork Sun
SPD has minor change from Rev 1.2 to 1.3. This patch enables Rev 1.3. The difference has ben examined and the code is compatible. Speed bins is not verified on hardware for CL7 at this moment. This patch also enables SPD Rev 1.x where x is up to "F". According to SPD spec, the lower nibble is optionally used to determine which additinal bytes or attribute bits have been defined. Software can safely use defaults. However, the upper nibble should always be checked. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
