* cbfs: new API and better program loadingAaron Durbin2015-06-021-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

* lib: add rmodule supportAaron Durbin2013-03-181-0/+126
A rmodule is short for relocation module. Relocaiton modules are standalone programs. These programs are linked at address 0 as a shared object with a special linker script that maintains the relocation entries for the object. These modules can then be embedded as a raw binary (objcopy -O binary) to be loaded at any location desired. Initially, the only arch support is for x86. All comments below apply to x86 specific properties. The intial user of this support would be for SMM handlers since those handlers sometimes need to be located at a dynamic address (e.g. TSEG region). The relocation entries are currently Elf32_Rel. They are 8 bytes large, and the entries are not necessarily in sorted order. An future optimization would be to have a tool convert the unsorted relocations into just sorted offsets. This would reduce the size of the blob produced after being processed. Essentialy, 8 bytes per relocation meta entry would reduce to 4 bytes.
