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.

2023-04-04cpu/x86/64bit/Makefile: use all_x86 make targetFelix Held
Use the newly introduced 'all_x86' make target to add the mode_switch.S compilation unit to all stages that run on the x86 cores, but not to verstage on PSP.

2023-04-04cpu/x86/64bit/Makefile: use verstage_x86 make targetFelix Held
Use the 'verstage_x86' make target for the mode_switch.S compilation unit instead of making adding it to the 'verstage' target depending on VBOOT_STARTS_BEFORE_BOOTBLOCK not being selected. The only case where VBOOT_STARTS_BEFORE_BOOTBLOCK is selected is the verstage on PSP case, so I find using the 'verstage_x86' target here a bit easier to understand.

2022-04-25cpu/x86/64bit: Generate static page tables from an assembly fileArthur Heymans
This removes the need for a tool to generate simple identity pages. Future patches will link this page table directly into the stages on some platforms so having an assembly file makes a lot of sense. This also optimizes the size of the page of each 4K page by placing the PDPE_table below the PDE.
