2016-05-09lib/prog_loaders: Allow platforms to skip stage cacheFurquan Shaikh
Before multi-CBFS support was added, x86 platforms cached their ramstage in TSEG so that it could be re-used on the resume path. However, more resources/assets are being put in cbfs that are utilized during ramstage. Just caching ramstage does not mean that correct cbfs region is used for all the data. Thus, provide an option to allow platforms to skip caching any component for resume.

2015-12-10cbfs/vboot: remove firmware component supportAaron Durbin
The Chrome OS verified boot path supported multiple CBFS instances in the boot media as well as stand-alone assets sitting in each vboot RW slot. Remove the support for the stand-alone assets and always use CBFS accesses as the way to retrieve data. This is implemented by adding a cbfs_locator object which is queried for locating the current CBFS. Additionally, it is also signalled prior to when a program is about to be loaded by coreboot for the subsequent stage/payload. This provides the same opportunity as previous for vboot to hook in and perform its logic. BUG=chromium:445938 BRANCH=None TEST=Built and ran on glados.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-06-02prog_loading: add region_device representing memoryAaron Durbin
One can remove the struct buffer_area and use the region_device embedded in the struct prog to represent the in-memory loaded program. Do this by introducing a addrspace_32bit mem_region_device that can have region_device operations performed on it. The addrspace_32bit name was chosen to make it explicit that 32-bits of address space is supported at the max.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.
