Instead of using platform_prog_run() for flushing programs from L1D to L2 for code coherency purposes use arch_segment_loaded() instead as that it's primary purpose.

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.

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.
