2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-07-02cpu/x86/pae/pgtbl: Add memset with PAEPatrick Rudolph
To clear all DRAM on x86_32, add a new method that uses PAE to access more than 32bit of address space. Add Documentation as well. Required for clearing all system memory as part of security API. Tested on wedge100s: Takes less than 2 seconds to clear 8GiB of DRAM. Tested on P8H61M-Pro: Takes less than 1 second to clear 4GiB of DRAM.

2018-04-26cpu/x86: add limited runtime identity page mappingAaron Durbin
When employing PAGING_IN_CACHE_AS_RAM more areas need to be mapped in at runtime. Therefore, paging_identity_map_addr() is added to support adding identity mappings. Because there are a fixed amount of pages in cache-as-ram paging only the existing paging structures can be used. As such that's a limitation on what regions and length one can map. Using util/x86/x86_page_tables.go to generate page tables will always populate all the page directory pages. Therefore, 2MiB mappings are easy to map in.

2018-04-25arch/x86: add support for cache-as-ram pagingAaron Durbin
Processors, such as glk, need to have paging enabled while in cache-as-ram mode because the front end is agressive about fetching lines into the L1I cache. If the line is dirty and in the L1D then it writes it back to "memory". However, in this case there is no backing store so the cache-as-ram data that was written back transforms to all 0xff's when read back in causing corruption. In order to mitigate the failure add x86 architecture support for enabling paging while in cache-as-ram mode. A Kconfig variable, NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve out for page tables within the cache-as-ram region. Additionally, the page directory pointer table is also carved out of cache-as-ram. Both areas are allocated from the persist-across-stages region of cache-as-ram so all stages utilizing cache-as-ram don't corrupt the page tables. The two paging-related areas are loaded by calling paging_enable_for_car() with the names of cbfs files to load the initial paging structures from.

2018-04-23cpu/x86: add paging_set_default_pat() functionAaron Durbin
Add paging_set_default_pat() which sets up the PAT MSR according to util/x86/x86_page_tables.go. Using page attribute types require a matching of the PAT values with the page table entries. This function is just providing the default PAT MSR value to match against the utility.

Add the following functions for use outside of the paging module: void paging_enable_pae_cr3(uintptr_t cr3); void paging_enable_pae(void); void paging_disable_pae(void); The functions just enable and/or disable paging along with PAE.
