| * powerpc/boot: Change the compile macro for SRIO & PCIE boot master moduleLiu Gang2012-10-222-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * powerpc/mpc85xx: software workaround for DDR erratum A-004468York Sun2012-10-226-15/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | P4080 Rev3.0 fixes ESDHC13 errata, so update the code to make the workaround conditional. In formal release document, the errata number should be ESDHC13 instead of ESDHC136. Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
| * powerpc mpc85xx: Only clear TSR:WIS in watchdog_reset.Mark Marshall2012-10-221-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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>
* | common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-2213-39/+0
| | | | | | | | | | | | | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

| | | | | | | | | | 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>
