2016-05-06cpu/x86: don't treat all chipsets the same regarding XIP_ROM_SIZEAaron Durbin
Previously, the XIP_ROM_SIZE Kconfig variable is used globally on x86 platforms with the assumption that all chipsets utilize this value. For the chipsets which do not use the variable it can lead to unnecessary alignment constraints in cbfs for romstage. Therefore, allow those chipsets a path to not be burdened by not passing '-P $(XIP_ROM_SIZE)' to cbfstool when adding romstage.

There used to be a need for an empty smm_init() function because initialize_cpus() called it even though nothing called initialize_cpus(). However, garbage collection at link time is implemented so there's no reason to provide an empty function to satisfy a symbol that is completely culled during link. Remove it.

2016-05-04cpu/x86: combine multiprocessor and SMM initializationAaron Durbin
In order to reduce code duplication provide a common flow through callback functions that performs the multiprocessor and optionally SMM initialization. The existing MP flight records are utilized but a common flow is provided such that the chipset/cpu only needs to provide a mp_ops structure which has callbacks to gather info and provide hooks at certain points in the sequence. All current users of the MP code can be switched over to this flow since there haven't been any flight records that are overly complicated and long. After the conversion has taken place most of the surface area of the MP API can be hidden away within the compilation unit proper.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state. This limitation is not documented in any public AMD errata, and was only discovered through considerable debugging effort.

2015-11-24FSP 1.0: Fix CAR issues - broken timestamps and consoleBen Gardner
FSP 1.0 has a fixed-size temporary cache size and address and the entire cache is migrated in the FSP FspInitEntry() function. Previous code expected the symbol _car_data_start to be the same as CONFIG_DCACHE_RAM_BASE and _car_data_end to be the same as _preram_cbmem_console. FSP 1.0 is the only one that migrates _preram_cbmem_console. Others leave that where it is and extract the early console data in cbmemc_reinit(). Special handling is needed to handle that. Commit dd6fa93d broke both assumptions and so broke the timestamp table and console. The fix is to use CONFIG_DCACHE_RAM_BASE when calculating the offset and to use _preram_cbmem_console instead of _car_data_end for the console check.

This patch allows us to disable the first couple of post codes that go out before the routing can be configured. The Kconfig symbol is selected by the cave creek chipset (fsp_i89xx).
