2016-03-12nb/amd/mct_ddr3: Consolidate duplicated codeTimothy Pearson
read_dqs_read_data_timing_registers() and read_read_dqs_timing_control_registers() served essentially the same function but had slightly different semantics, causing confusion and needlessly complex Family15h code. Consolidate both into read_dqs_read_data_timing_registers() and adjust surrounding code to match new semantics.

2016-03-11nb/amd/mct_ddr3: Set read DQS delay to 1UI before calculating read latencyTimothy Pearson
The AMD Family 15h BKDG rev. 3.14 indicates that the maximum read latency must be calculated prior to DQS position training, however the read latency calculations use read DQS delay values that have not been set prior to DQS position training. Set the read DQS delay values to 1UI (i.e worst case) before calculating the read latency prior to DQS position training.

2016-02-05nb/amd/mct_ddr3: Work around RDIMM training failureTimothy Pearson
Under certain conditions, not elucidated in the BKDG, an extra memclock of CAS write latency is required. The only reliable way I have found to detect when this is required is to try training without the delay, and if DQS position training fails, adding the delay and retraining. This is probably related in some form or another to the badly broken DQS Write Early algorithm given in the BKDG.

2015-11-11amd/amdmct/mct_ddr3: Improve SPD DIMM detect reliabilityTimothy Pearson
Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over I2C on a system with all DIMM slots populated. If even one of those reads has a single flipped bit in it (due to EMI, cross coupling with another trace, or just poor margins on some cheap DIMM) the system will hang and require a hard reset. In practice I've seen failure rates as high as 1 failed boot in 50 due to this issue, granted with cheap DIMMs, but even so retrying the read resolves the corruption issue. I2C is not designed for continuous data transmission with high reliability, and there is no hardware error checking, therefore a single retry when transferring this amount of data makes sense.

2015-11-06AMD bettong: Fix the interrupt routing.zbao
The plugged devices on PCIe should use IOAPIC2 instead of standard IOAPIC1. The entries in IOAPIC2 count from the end of IOAPIC1. The unchanged code worked because the OS uses MSI instead APIC. To test that, boot linux with parameter pci=nomsi and see if the devices like NIC work well as they do without the booting parameter.

2015-11-05src/amd: Increase maximum blootblock execution countTimothy Pearson
Most AMD hardware requires at minimum two warm resets when booting from S5 (power off). This is uncomfortably close to the maximum bootblock execution count, and has resulted in unstable normal/fallback operation on some machines. Increase the default max bootblock execution count before fallback to 6. This translates to roughly 2 - 3 failed boots before fallback mode will engage, with an absolute worst case of pushing the reset button 5 times to engage fallback mode in the absence of a dedicated recovery jumper.
