2014-03-07x86: add MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING optionAaron Durbin
Boot speeds can be sped up by mirroring the payload into main memory before doing the actual loading. Systems that would benefit from this are typically Intel ones whose SPI are memory mapped. Without the SPI being cached all accesses to the payload in SPI while being loaded result in uncacheable accesses. Instead take advantage of the on-board SPI controller which has an internal cache and prefetcher by copying 64-byte cachelines using 32-bit word copies.

2014-03-03selfboot: use bootmem infrastructureAaron Durbin
Instead of packing and unpacking entries in lb_mem use the bootmem infrastructure for performing sanity checks during payload loading.

2014-03-03coreboot: introduce arch_payload_run()Aaron Durbin
The selfboot() function relied on global variables within the selfboot.c compilation unit. Now that the bounce buffer is a part of struct payload use a new architecture-specific arch_payload_run() function for jumping to the payload. selfboot() can then be removed.

2014-03-03selfboot: store bounce buffer in struct payloadAaron Durbin
In order to break the dependency on selfboot for jumping to payload the bounce buffer location needs to be communicated. Therefore, add the bounce buffer to struct payload.

2014-03-03coreboot: use struct payload for selfload()Aaron Durbin
In order to encapsulate more data for self loading use struct payload as the type. That way modifications to what is needed for payload loading does not introduce more global variables.

2014-03-03coreboot: unify infrastructure for loading payloadsAaron Durbin
A payload can be loaded either from a vboot region or from cbfs. Provide a common place for choosing where the payload is loaded from. Additionally, place the logic in the 'loaders' directory similarly to the ramstage loader infrastructure.
