2012-10-22powerpc/mpc8xxx: Add auto select bank interleaving modeYork Sun
Based on populated DIMMs, automatically select from cs0_cs1_cs2_cs3 or cs0_cs1 interleaving, or non-interleaving if not available. Fix the message of interleaving disabled if controller interleaving is enabled but DIMMs don't support it.

2012-10-22powerpc/mpc85xx: Add workaround for DDR erratum A004934York Sun
After DDR controller is enabled, it performs a calibration for the transmit data vs DQS paths. During this calibration, the DDR controller may make an inaccurate calculation, resulting in a non-optimal tap point.

2012-10-22powerpc/mpc85xx: software workaround for DDR erratum A-004468York Sun
Boot space translation utilizes the pre-translation address to select the DDR controller target. However, the post-translation address will be presented to the selected DDR controller. It is possible that the pre- translation address selects one DDR controller but the post-translation address exists in a different DDR controller when using certain DDR controller interleaving modes. The device may fail to boot under these circumstances. Note that a DDR MSE error will not be detected since DDR controller bounds registers are programmed to be the same when configured for DDR controller interleaving.

2012-10-22powerpc/mpc8xxx: Fix DDR initialization waiting for D_INITYork Sun
When ECC is enabled, DDR controller needs to initialize the data and ecc. The wait time can be calcuated with total memory size, bus width, bus speed and interleaving mode. If it went wrong, it is bettert to timeout than waiting for D_INIT to clear, where it probably hangs.

2012-10-22powerpc/mpc8xxx: Fix DDR driver handling quad-rank DIMMs and address calculationYork Sun
Fix handling quad-rank DIMMs in a system with two DIMM slots and first slot supports both dual-rank DIMM and quad-rank DIMM. For systems with quad-rank DIMM and double dual-rank DIMMs, cs_config registers need to be enabled to maintain proper ODT operation. The inactive CS should have bnds registers cleared. Fix the turnaround timing for systems with all chip-selects enabled. This wasn't an issue before because DDR was running lower than 1600MT/s with this interleaving mode. Fix DDR address calculation. It wasn't an issue until we have multiple controllers with each more than 4GB and interleaving is disabled. It also fixes the message of DDR: 2 GiB (DDR3, 64-bit, CL=0.5, ECC off) when debugging DDR and first DDR controller is disabled. With the fix, the first enabled controller information will be displayed. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-10-22powerpc/mpc8xxx: Update DDR registersYork Sun
DDRC ver 4.7 adds DDR_SLOW bit in sdram_cfg_2 register. This bit needs to be set for speed lower than 1250MT/s. CDR1 and CDR2 are control driver registers. ODT termination valueis for IOs are defined. Starting from DDRC 4.7, the decoding of ODT for IOs is 000 -> Termsel off 001 -> 120 Ohm 010 -> 180 Ohm 011 -> 75 Ohm 100 -> 110 Ohm 101 -> 60 Ohm 110 -> 70 Ohm 111 -> 47 Ohm Add two write leveling registers. Each QDS now has its own write leveling start value. In case of zero value, the value of QDS0 will be used. These values are board-specific and are set in board files. Extend DDR register timing_cfg_1 to have 4 bits for each field. DDR control driver registers and write leveling registers are added to interactive debugging for easy access.

2012-10-22powerpc/mpc85xx: Fix core cluster PLL calculation for Chassis generation 2York Sun
Corenet based SoCs have different core clocks starting from Chassis generation 2. Cores are organized into clusters. Each cluster has up to 4 cores sharing same clock, which can be chosen from one of three PLLs in the cluster group with one of the devisors /1, /2 or /4. Two clusters are put together as a cluster group. These two clusters share the PLLs but may have different divisor. For example, core 0~3 are in cluster 1. Core 4~7 are in cluster 2. Core 8~11 are in cluster 3 and so on. Cluster 1 and 2 are cluster group A. Cluster 3 and 4 are in cluster group B. Cluster group A has PLL1, PLL2, PLL3. Cluster group B has PLL4, PLL5. Core 0~3 may have PLL1/2, core 4~7 may have PLL2/2. Core 8~11 may have PLL4/1. PME and FMan blocks can take different PLLs, configured by RCW.

Add a new device tree property named "fsl,liodn-offset-list" holding a list of per pci endpoint permitted liodn offsets. This property is useful in virtualization scenarios that implement per pci endpoint partitioning. The final liodn of a partitioned pci endpoint is calculated by the hardware, by adding these offsets to pci controller's base liodn, stored in the "fsl,liodn" property of its node. The liodn offsets are interleaved to get better cache utilization.

2012-10-22powerpc/srio: Workaround for srio erratrm a004034Liu Gang
Erratum: A-004034 Affects: SRIO Description: During port initialization, the SRIO port performs lane synchronization (detecting valid symbols on a lane) and lane alignment (coordinating multiple lanes to receive valid data across lanes). Internal errors in lane synchronization and lane alignment may cause failure to achieve link initialization at the configured port width. An SRIO port configured as a 4x port may see one of these scenarios: 1. One or more lanes fails to achieve lane synchronization. Depending on which lanes fail, this may result in downtraining from 4x to 1x on lane 0, 4x to 1x on lane R (redundant lane). 2. The link may fail to achieve lane alignment as a 4x, even though all 4 lanes achieve lane synchronization, and downtrain to a 1x. An SRIO port configured as a 1x port may fail to complete port initialization (PnESCSR[PU] never deasserts) because of scenario 1. Impact: SRIO port may downtrain to 1x, or may fail to complete link initialization. Once a port completes link initialization successfully, it will operate normally.

2012-10-22fs: Add a Coreboot Filesystem (CBFS) driver and commandsGabe Black
This change adds CBFS support and some commands to use it to u-boot. These commands are: cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of the ROM is an optional parameter which defaults to the standard 0xffffffff and can be used to support multiple CBFSes in a system. The last one set up with cbfsinit is the one that will be used. cbfsinfo - Print information from the CBFS header. cbfsls - Print out the size, type, and name of all the files in the current CBFS. Recognized types are translated into symbolic names. cbfsload - Load a file from CBFS into memory. Like the similar command for fat filesystems, you can optionally provide a maximum size. Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified. The CBFS driver can also be used programmatically from within u-boot. If u-boot needs something out of CBFS very early before the heap is configured, it won't be able to use the normal CBFS support which caches some information in memory it allocates from the heap. The cbfs_file_find_uncached function searches a CBFS instance without touching the heap.

2012-10-22common: Convert the U-Boot commands to LG-arraysMarek Vasut
This patch converts the old method of creating a list of command onto the new LG-arrays code. The old u_boot_cmd section is converted to new u_boot_list_cmd subsection and LG-array macros used as needed. Minor adjustments had to be made to the common code to work with the LG-array macros, mostly the fixup_cmdtable() calls are now passed the ll_entry_start and ll_entry_count instead of linker-generated symbols. The command.c had to be adjusted as well so it would use the newly introduced LG-array API instead of directly using linker-generated symbols.

Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Joe Hershberger <joe.hershberger@gmail.com> Cc: Mike Frysinger <vapier@gentoo.org>
2012-10-22common: Implement support for linker-generated arraysMarek Vasut
This patch adds support for linker-generated array. These arrays are a generalization of the U-Boot command declaration approach. Basically, the idea is to generate an array, where elements of the array are statically initialized at compile time and each element is declared separatelly at different place. Such array is assembled together into continuous piece of memory by linker and a pointer to it's first entry can then be retrieved via accessor. The actual implementation relies on placing any variable that is to represent an element of LG-array into particular subsection of the .u_boot_list linker section . The subsection is determined by user options. Once compiled, it is possible to dump all symbols placed in .u_boot_list section and the subsections in which they should be and generate appropriate bounds for each requested subsection of the .u_boot_list section. Each such subsection thus contains __start and __end entries at the begining and end respecitively. This allows for simple run-time traversing of the array, since the symbols are properly defined.

2012-10-22common: Add symbol handling for generic lists into MakefileMarek Vasut
This patch adds essential components for generation of the contents of the linker section that is used by the linker-generated array. All of the contents is held in a separate file, u-boot.lst, which is generated at runtime just before U-Boot is linked. The purpose of this code is to especially generate the appropriate boundary symbols around each subsection in the section carrying the linker-generated arrays. Obviously, the interim linker code for actual placement of the variables into the section is generated too. The generated file, u-boot.lst, is included into u-boot.lds via the linker INCLUDE directive in u-boot.lds . Adjustments are made in the Makefile and spl/Makefile so that the u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

2012-10-22powerpc mpc85xx: Only clear TSR:WIS in watchdog_reset.Mark Marshall
We should only write TSR_WIS to the SPRN_TSR register in reset_85xx_watchdog. The old code would cause the timer interrupt to be acknowledged when the watchdog was reset, and we would then get no more timer interrupts. This bug would affect all mpc85xx boards that have the watchdog enabled. Signed-off-by: Mark Marshall <Mark.Marshall@omicron.at> Signed-off-by: Andy Fleming <afleming@freescale.com>
