2023-08-06cpu: Add SPDX license headers to MakefilesMartin Roth
To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the cpu directory that don't already have an SPDX license line at the top.

2021-03-17cbfs: Replace more instances of cbfs_boot_locate() with newer APIsJulius Werner
In pursuit of the eventual goal of removing cbfs_boot_locate() (and direct rdev access) from CBFS APIs, this patch replaces all remaining "simple" uses of the function call that can easily be replaced by the newer APIs (like cbfs_load() or cbfs_map()). Some cases of cbfs_boot_locate() remain that will be more complicated to solve.

2020-06-23src/*: Update makefiles to exclude x86 code from psp-verstageMartin Roth
The assumption up to this point was that if the system had an x86 processor, verstage would be running on the x86 processor. With running verstage on the PSP, that assumption no longer holds true, so exclude pieces of code that cause problems for verstage on the PSP. This change will add these files to verstage only if the verstage architecture is X86 - either 32 or 64 bit.

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

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.

2012-07-02Use broadcast SIPI to startup siblingsSven Schnelle
The current code for initializing AP cpus has several shortcomings: - it assumes APIC IDs are sequential - it uses only the BSP for determining the AP count, which is bad if there's more than one physical CPU, and CPUs are of different type Note that the new code call cpu->ops->init() in parallel, and therefore some CPU code needs to be changed to address that. One example are old Intel HT enabled CPUs which can't do microcode update in parallel.

2010-09-30Rename build system variables to be more intuitive, andPatrick Georgi
at the same time let the user specify sources instead of object files: - objs becomes ramstage-srcs - initobjs becomes romstage-srcs - driver becomes driver-srcs - smmobj becomes smm-srcs The user servicable parts are named accordingly: ramstage-y, romstage-y, driver-y, smm-y Also, the object file names are properly renamed now, using .ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently. Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't easily fit in the build system and aren't useful anyway.

2009-04-30Remove warnings from compilation of the s2892 with and without CBFS.Myles Watson
I didn't try to remove "defined but not used" warnings because there are too many ifdefs to be sure I wouldn't break something. For shadowed variable declarations I renamed the inner-most variable. The one in src/pc80/keyboard.c might need help. I didn't change the functionality but it looks like a bug. I boot tested it on s2892 and abuild tested it.
