| * powerpc/boot: Change the compile macro for SRIO & PCIE boot master moduleLiu Gang2012-10-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

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.

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

* serial: powerpc: Implement CONFIG_SERIAL_MULTI into mpc85xx serial driverMarek Vasut2012-10-15-11/+60
| | | | | | | | | | | | | | Implement support for CONFIG_SERIAL_MULTI into mpc85xx serial driver. This driver was so far only usable directly, but this patch also adds support for the multi method. This allows using more than one serial driver alongside the mpc85xx driver. Also, add a weak implementation of default_serial_console() returning this driver.

* powerpc/fsl-corenet: work around erratum A004510Scott Wood2012-08-23-0/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Erratum A004510 says that under certain load conditions, modified cache lines can be discarded, causing data corruption. To work around this, several CCSR and DCSR register updates need to be made in a careful manner, so that there is no other transaction in corenet when the update is made. The update is made from a locked cacheline, with a delay before to flush any previous activity, and a delay after to flush the CCSR/DCSR update. We can't use a readback because that would be another corenet transaction, which is not allowed. We lock the subsequent cacheline to prevent it from being fetched while we're executing the previous cacheline. It is filled with nops so that a branch doesn't cause us to fetch another cacheline. Ordinarily we are running in a cache-inhibited mapping at this point, so we temporarily change that. We make it guarded so that we should never see a speculative load, and we never do an explicit load. Thus, only the I-cache should ever fill from this mapping, and we flush/unlock it afterward. Thus we should avoid problems from any potential cache aliasing between inhibited and non-inhibited mappings. NOTE that if PAMU is used with this patch, it will need to use a dedicated LAW as described in the erratum. This is the responsibility of the OS that sets up PAMU.

| | | | | | | | | | | | | | | | | | | | | | Get rid of the SRIOBOOT_MASTER build target, and to support for serving as a SRIO boot master via environment variable. Set the environment variable "bootmaster" to "SRIO1" or "SRIO2" using the following command: setenv bootmaster SRIO1 saveenv The "bootmaster" will enable the function of the SRIO boot master, and this has the following advantages compared with SRIOBOOT_MASTER build configuration: 1. Reduce a build configuration item in boards.cfg file. No longer need to build a special image for master, just use a normal target image and set the "bootmaster" variable. 2. No longer need to rebuild an image when change the SRIO port for boot from SRIO, just set the corresponding value to "bootmaster" based on the using SRIO port.
