2011-01-14powerpc/85xx: Add the workaround for erratum ELBC-A001 (enable on P4080)Kumar Gala

2011-01-14powerpc/86xx: Enable common SRIO init codeKumar Gala
Add the needed defines and code to utilize the common 8xxx srio init code to setup LAWs and modify device tree if we have SRIO enabled on a board. 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>
2011-01-14fsl_pci: Update PCIe boot ouputPeter Tyser
This change does the following: - Adds printing of negotiated link width. This information can be useful when debugging PCIe issues. - Makes it optional for boards to implement board_serdes_name(). Previously boards that did not implement it would print unsightly output such as "PCIE1: Connected to <NULL>..." - Rewords the PCIe boot output to reduce line length and to make it clear that the "base address XYZ" value refers to the base address of the internal processor PCIe registers and not a standard PCI BAR value. - Changes "PCIE" output to the standard "PCIe" Before change: PCIE1: connected to <NULL> as Root Complex (base addr ef008000) 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 05 PCIE2: connected to <NULL> as Endpoint (base addr ef009000) PCIE2: Bus 06 - 06 After change: PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIe1: Bus 00 - 05 PCIe2: Endpoint of VPX Fabric A, x2, regs @ 0xef009000 PCIe2: Bus 06 - 06 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-01-14powerpc/fsl-pci: Add generic code to setup PCIe controllersKumar Gala
Since all the PCIe controllers are connected over SERDES on the SoCs we can utilize is_serdes_configured() to determine if a controller is enabled. After which we can setup the ATMUs and LAWs for the controller in a common fashion and allow board code to specify what the controller is connected to for reporting reasons. We also provide a per controller (rather than all) for some systems that may have special requirements. Finally, we refactor the code used by the P1022DS to utilize the new generic code.

2011-01-14powerpc/fsl-pci: Determine pci_controller based on cfg addr for dts fixupKumar Gala
Previously we passed in a specifically named struct pci_controller to determine if we had setup the particular PCI bus. Now we can search for the struct so we dont have to depend on the name or the struct being statically allocated. Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct back by searching for it means we can do things like dynamically allocate them or not have to expose the static structures to all users.

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>
2011-01-14mpc85xx/tlb.c: Allow platforms to specify wimge bitsBecky Bruce
Some platforms might want to override the default wimge=0 for DDR. Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use. This will initially only be used by TQM85xx, but could be useful for other boards or testing going forward. Note that the name of this define is not 85xx-specific. WIMGE is a fairly universal concept, so any ppc platforms that require different WIMGE settings for DDR can use the same #define.

2011-01-10microblaze: Fix bd_info pointerMichal Simek
Patch "Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value" (sha1: 25ddd1fb0a2281b182529afbc8fda5de2dc16d96) introduce GENERATED_GBL_DATA_SIZE which is sizeof aligned gd_t (currently 0x40). Microblaze configs used 0x40(128) because this place also contained board info structure which lies on the top of ram. U-Boot is placed to the top of the ram (for example 0xd7ffffff) and bd structure was moved out of ram. This patch is fixing this scheme with GENERATED_BD_INFO_SIZE which swap global data and board info structures.
