2016-07-24soc/intel/apollolake: ensure usb port 0 is in host modeAaron Durbin
The controller for device mode USB is not plan of record on apollolake.

2016-07-13soc/intel/apollolake: add initial ITSS supportAaron Durbin
The interrupt and timer subsystem (ITSS) sits between the APIC and the other logic blocks. It only supports positive polarity events, but there's a polarity inversion setting for each IRQ such that it can pass the signal on to the APIC according to the expected APIC redirection entry values. This support is needed in order for the platform/board to set the expected interrupt polarity into the APIC for gpio signals.

Add the Audio DSP device for apollolake as a PCI driver with a static scan_bus handler so generic devices can be declared under it. This is for devices like the Maxim 98357A which is connected on the I2S bus for data but has no control channel bus and instead just has a GPIO for channel selection and power down control and needs to describe that GPIO connection to the OS via ACPI.

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. BUG=chrome-os-partner:53017 TEST=Ensured P2SB device is visible and pci resources are allocated correctly for the devices.

2016-04-02soc/intel/apollolake: use CAR code coherency for all CAR stagesAaron Durbin
The flush L1D to L2 operation was only being used when loading romstage from bootblock. However, when the FSP-M component is loaded no code coherency actions are taken. I suspect this is because the FSP-M component is larger than the 24KiB L1D and the entry point is early in the image. Thus, when loading the FSP-M component the earlier part of the image is flushed out to L2 in the process of loading the latter part of the component. Also, once verstage is introduced the same code coherency actions need to be taken as well. Therefore, position the apollolake code to handle all these cases.

This is different from past platforms where they were just executing-in-place against the memory-mapped SPI flash boot media. The implication is that when cache-as-ram needs to be torn down one needs to be executing out of DRAM since the act of cache-as-ram going away means the code disappears out from under the processor.

On Apollo Lake SPI flash is memory mapped. The mapping is different to previous platforms. Only "BIOS" region is mapped in contrast to whole flash. Also, the 128 KiB right below 4 GiB are being decoded by readonly SRAM. Fail accesses to those regions, rather than returning false data.

2016-02-26soc/intel/apollolake: group serial console options into one KconfigAaron Durbin
Add SOC_UART_DEBUG which does all the appropriate selection of the dependent Kconfig options for seral console. Also provide a default option of it being turned off instead of always selected.

2016-02-11soc/apollolake: Add early serial driver for BOOTBLOCK_CONSOLEAndrey Petrov
Early UART driver is for bootblock and romstage. It is supposed to be used when BOOTBLOCK_CONSOLE is enabled. This also adds few configuration bits in bootblock requiered for serial to be set up.

2016-02-11soc/apollolake: Add initial cache-as-ram setup for bootblockAlexandru Gagniuc
This is the minimum setup needed to both get cache-as-ram setup and a C environment working. On apollolake, we only get 32 KiB of data loaded into an SRAM that is readonly to the main CPU. Due to this restriction we have to set CAR and a C environment very early on.
