2016-04-11	soc/intel/apollolake: Enable CACHE_MRC_SETTINGS	Hannah Williams
	This enables CACHE_MRC_SETTINGS by default as well selects timer configuration.

2016-04-11	soc/intel/apollolake: Implement SPI controller driver	Alexandru Gagniuc
	Implement flash read, write, and erase functionality using the hardware sequencing capabilities of the SOC. Due to changes in hardware requirements, the flash chip must be probed differently than on previous platforms (details explained in comments). Note that this is a minimal implementation, and does not provide all the bells and whistles.

2016-03-23	soc/intel/apollolake: utilize postcar phase/stage	Aaron 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.

2016-03-11	soc/intel/apollolake: Avoid hardcoding CAR region size for FSPM	Andrey Petrov
	Instead of having to supply CAR memory region during compilation time it is possible to determine it in runtime. FSP2.0 blobs carry a copy of UPD structure pre-populated with 'default' values. The default value for StackSize is actually the real value blob needs.

2016-03-08	soc/intel/apollolake: Add romstage that calls FSP2.0 driver	Andrey Petrov
	This romstage is minimalistic. Its goal is to set up some BARs that FSP expects to be set and then invoke FSP driver to train memory.

2016-03-08	soc/intel/apollolake: Add support for memory-mapped boot media	Andrey Petrov
	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.

2016-02-13	soc/intel/apollolake: limit bootblock size to 32KiB	Aaron Durbin
	The CSE places the bootblock (IBBL in Intel parlance) below 4GiB at top of the address space. However, it's size is limited to 32KiB. For now, just limit all of bootblock to 32KiB.

2016-02-11	soc/apollolake: Add early serial driver for BOOTBLOCK_CONSOLE	Andrey 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.

2016-02-11	soc/apollolake: Add initial cache-as-ram setup for bootblock	Alexandru 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.
