2012-11-12SPI: Add early romstage SPI driver using hardware sequencingDuncan Laurie
This is a basic romstage driver that can be used for the MRC cache code on systems where we do not have the MRC cache stored in a flash region that is memory mapped. It uses the hardware sequencing interface to avoid having to know anything about the flash chip itself. BUG=chrome-os-partner:15031 BRANCH=stout TEST=manual: this was tested with debug code added to romstage that attempted to read the MRC cache at offset 0x3e0000.

2012-07-24CPU: Set flex ratio to nominal TDP ratio in bootblockDuncan Laurie
CPUs with configurable TDP will run the TSC at the max non-turbo ratio for the maximum TDP value, which can cause issues if another TDP is desired. To deal with this we set the flex ratio to the nominal TDP ratio early in the boot and then configure the Soft Reset Data registers so the PCH can tell the CPU what frequency to run at after a reset. This is done very early in the bootblock because it is necessary to reset the system after setting a flex ratio. The end result is that the TSC will now increment at the max non-turbo frequency for the nominal TDP. On some system with 1.8GHz CPU ensure that the kernel detects the CPU speed as ~1800mhz rather than ~2300mhz: > dmesg | grep "MHz processor" [ 0.004000] Detected 1795.801 MHz processor.

2012-05-01Add an option to enable PCIe root port coalescingDuncan Laurie
Background: The PCI spec (3.0-3.2.2.3.4) requires that PCI devices implement function 0. The Linux Kernel therefore will not enumerate a PCI device if it does not present a valid config space at function 0. If a board does not have anything connected to root port 0 and it is desired to disable the unused ports in order to save power then this will cause the other downstream PCIe devices to go missing as they will not be enumerated. Intel chipsets provide a way to map root port numbers to different PCI function numbers, thereby avoiding this issue and allowing root port 0 to be turned off. This change adds a new chip config option 'pcie_port_coalesce' that will collapse the enabled root ports into a linear map starting at zero. This option defaults to disabled as it can have a confusing effect on the system as the declared static devicetree may not match what is seen at runtime. This option is also forced on if the static devicetree disables port 0. When each root port is processed in the early enable stage it looks for a lower numbered root port that has been disabled and then swaps the two assigned function numbers. However the mapping register is write-once so it has to keep track of the proposed mapping changes until all ports have been processed before writing out the final map value. At this point it also updates the function numbers in the static device tree so they are consistent with the new layout. There are a few other closely related fixes in this change: 1) There is a power savings opportunity if an entire bank of ports (0-3 or 4-7) are disabled. This was checking the chipset revision to look for CougarPoint B1+ stepping and that was not passing on PantherPoint where this should always be applied. To fix this I added a function to determine the chipset type based on comparing the upper byte of the device ID. 2) Apply the same chipset type check fix to the IOBP programming. 3) There is another power savings opportunity to enable dynamic clock gating on shared PCIe resources which only applies to ports 0 and 4. However if 0 or 4 is disabled then the later check to enable this would fail as that device is already hidden.
