2016-07-02soc/intel/apollolake: handle p2sb quirksAaron Durbin
The P2SB device is device 0xd and function 0. If hidden that causes the latter pci devices on function >= 1 to not be probed in the kernel. This is also a problem for coreboot if the P2SB device is hidden by FSP. That means the coreboot driver won't be ran. Therefore, provide hide and unhide functions for the P2SB device. The other quirk is to allow the GPIO devices to work correctly. Those devices are ACPI devices. However, their resources are sub-regions within the P2SB BAR. Sadly, linux doesn't handle ACPI devices being children of PCI devices. This leads to resource conflict errors when the P2SB device is visible. For the time being keep the P2SB device hidden, but also ensure the resources it is using are accounted for and reserved. The fallout of that is the PMC and SPI device are no longer probed by the kernel.

Global reset enable bit is not cleared on reset. Therefore, clear the bit early. Lock down 0xcf9 so that payload/OS can't issue global reset.

2016-06-24soc/intel/apollolake: Add utility functions for global resetAndrey Petrov
Apollolake defines Global Reset where Host, TXE and PMC are reset. During boot we may need to trigger a global reset as part of platform initialization (or for error handling). Add functions to trigger global reset, enable/disable it and lock global reset bit.

2016-06-21intel/apollolake: Enable SPI properly in bootblock and ramstageFurquan Shaikh
Bootblock: - Temporary BAR needs to be assigned for SPI device until PCI enumeration is done by ramstage which allocates a new BAR. - Call spi_init to allow bootblock/verstage to write/erase on flash. Ramstage: - spi_init needs to run in ramstage to allow write protect to be disabled for eventlog and NVRAM updates. This needs to be done pretty early so that any init calls(e.g. mainboard_ec_init) writing to flash work properly. Verified with this change that there are no more flash write/erase errors for ELOG/NVRAM.

On apollolake, the boot media layout is different in that the traditional "BIOS" region contains another data structure with the boot assets such as CSE firmware, PMC microcode, CPU microcode, and boot firmware to name a few. This region is referred to as the IFWI. Add support for writing the IFWI to a specified FMAP region to accommodate such platforms.

There previously was no support for building verstage on apollolake. Add that suport by linking in the appropriate modules as well as providing vboot_platform_is_resuming(). The link address for verstage is the same as FSP-M because they would never be in CAR along side each other. Additionally, program the ACPI I/O BAR and enable decoding so sleep state can be determined for early firmware verification.
