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.

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.

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.

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.

This allows interoperability of equipment from different vendors,and preserves the software investment made by wireless service providers.

Features of B4860 are (incomplete list): Six fully-programmable StarCore SC3900 FVP subsystems, divided into three clusters-each core runs up to 1.2 GHz, with an architecture highly optimized for wireless base station applications Four dual-thread e6500 Power Architecture processors organized in one cluster-each core runs up to 1.8 GHz Two DDR3/3L controllers for high-speed, industry-standard memory interface each runs at up to 1866.67 MHz MAPLE-B3 hardware acceleration-for forward error correction schemes including Turbo or Viterbi decoding, Turbo encoding and rate matching, MIMO MMSE equalization scheme, matrix operations, CRC insertion and check, DFT/iDFT and FFT/iFFT calculations, PUSCH/PDSCH acceleration, and UMTS chip rate acceleration CoreNet fabric that fully supports coherency using MESI protocol between the e6500 cores, SC3900 FVP cores, memories and external interfaces. CoreNet fabric interconnect runs at 667 MHz and supports coherent and non-coherent out of order transactions with prioritization and bandwidth allocation amongst CoreNet endpoints. Data Path Acceleration Architecture, which includes the following: Frame Manager (FMan), which supports in-line packet parsing and general classification to enable policing and QoS-based packet distribution Queue Manager (QMan) and Buffer Manager (BMan), which allow offloading of queue management, task management, load distribution, flow ordering, buffer management, and allocation tasks from the cores Security engine (SEC 5.3)-crypto-acceleration for protocols such as IPsec, SSL, and 802.16 RapidIO manager (RMAN) - Support SRIO types 8, 9, 10, and 11 (inbound and outbound). Supports types 5, 6 (outbound only) Large internal cache memory with snooping and stashing capabilities for bandwidth saving and high utilization of processor elements. The 9856-Kbyte internal memory space includes the following: 32 Kbyte L1 ICache per e6500/SC3900 core 32 Kbyte L1 DCache per e6500/SC3900 core 2048 Kbyte unified L2 cache for each SC3900 FVP cluster 2048 Kbyte unified L2 cache for the e6500 cluster Two 512 Kbyte shared L3 CoreNet platform caches (CPC) Sixteen 10-GHz SerDes lanes serving: Two Serial RapidIO interfaces.

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.

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.

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.
