2012-10-23mpc83xx: add support for mpc8309Gerlando Falauto
This processor, though very similar to other members of the PowerQUICC II Pro family (namely 8308, 8360 and 832x), provides yet another feature set than any supported sibling. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

Introduce a new configuration token CONFIG_MPC830x to be shared among mpc8308 and mpc8309. Define it for existing 8308 boards, and refactor existing common code so to make future introduction of 8309 simpler.

2012-10-22powerpc/boot: Change the compile macro for SRIO & PCIE boot master moduleLiu Gang
Currently, the SRIO and PCIE boot master module will be compiled into the u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this macro has been included by all the corenet architecture platform boards. But in fact, it's uncertain whether all corenet platform boards support this feature. So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add a special macro for every board which can support the feature. This special macro will be defined in the header file "arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO and PCIE boot master module should be compiled into the board u-boot image.

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.

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.

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.

2012-10-22powerpc/p5040ds: add per pci endpoint liodn offset listLaurentiu Tudor
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. As an example, given 3 pci controllers, the following liodns are generated for the pci endpoints: pci0: 193 256 259 262 265 268 271 274 277 pci1: 194 257 260 263 266 269 272 275 278 pci2: 195 258 261 264 267 270 273 276 279 Signed-off-by: Laurentiu Tudor <Laurentiu.Tudor@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

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.

2012-10-22powerpc 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>
2012-10-22mpc85xx: make gpio_direction_output respect valueChris Packham
Users of familiar with the Linux gpiolib API expect that value parameter to gpio_direction_output reflects the initial state of the output pin. gpio_direction_output was always driving the output low, now it drives it high or low according to the value provided.

2012-10-17split mpc8xx hooks from cmd_ide.cPavel Herrmann
move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created ide_init_postreset() (invoked after calling ide_reset after ide_preinit), some cleanup to make checkpatch happy, enable IDE init hooks in configs of affected boards. confusingly, these hooks are used by more than just mpc8xx-based boards, and therefore are placed in arch/ppc/lib/ note: checkpatch still emits warnings about using volatile Signed-off-by: Pavel Herrmann <morpheus.ibis@gmail.com>
2012-10-17serial: Use default_serial_puts() in driversMarek Vasut
Replace the in-place ad-hoc implementation of serial_puts() within the drivers with default_serial_puts() call. This cuts down on the code duplication quite a bit. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>
