2016-05-12soc/apollolake: Handle non-standard ACPI BAR in PMC deviceAlexandru Gagniuc
The ACPI BAR (BAR2 - offset 0x20) is not PCI compliant. That means that probing may not work. In that case, a resource still needs to be created for the BAR. BONUS: We now avoid the need to declare the MMIO resources as fixed.

2016-05-12soc/apollolake/uart.c: Do not NOOP .set_resources() and friendsAlexandru Gagniuc
When SOC_UART_DEBUG was not set, the boot would hang somwhere in ramstage, as evidenced by POST codes reported from the EC. This was traced to the .set_resources and .enable_resources members of the UART PCI driver being set to NOOP. Although the exact mechanism of failure is not known, this change eliminates the hang.

2016-05-09drivers/uart: Use uart_platform_refclk for all UART modelsLee Leahy
Allow the platform to override the input clock for the UART by implementing the routine uart_platform_refclk and setting the Kconfig value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk routine which is disabled when UART_OVERRIDE_REFCLK is selected. This works around ROMCC not supporting weak routines. Testing on Galileo: * Edit the src/mainboard/intel/galileo/Makefile.inc file: * Add "select ADD_FSP_PDAT_FILE" * Add "select ADD_FSP_RAW_BIN" * Add "select ADD_RMU_FILE" * Place the FSP.bin file in the location specified by CONFIG_FSP_FILE * Place the pdat.bin files in the location specified by CONFIG_FSP_PDAT_FILE * Place the rmu.bin file in the location specified by CONFIG_RMU_FILE * Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate UEFIPAYLOAD.fd * Testing is successful when CorebootPayloadPkg is able to properly initialize the serial port without using built-in values.

Note that we cannot do the same for the ACPI BAR (index 0x20), as it cannot be read back.

2016-05-09xip: Do not pass --xip for early stages if CAR supports code executionFurquan Shaikh
On modern x86 platforms like apollolake, pre-RAM stages verstage and romstage run within the cache-as-ram region. Thus, we do not need to pass in the --xip parameter to cbfstool while adding these stages. Introduce a new Kconfig variable NO_XIP_EARLY_STAGES which is default false for all x86 platforms. Apollolake selects this option since it supports code execution with CAR.

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.

2016-03-23soc/intel/apollolake: utilize postcar phase/stageAaron Durbin
The current Apollolake flow has its code executing out of cache-as-ram for the pre-DRAM stages. 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. Therefore load and use the postcar infrastructure to bootstrap this process for tearing down cache-as-ram and subsequently loading ramstage.
