2019-11-04cpu/intel/car/p4-netburst: Remove delay loopsKyösti Mälkki
While commented as 10 ms + 250 us, those delay loops actually accounted for a total of 840 ms. And they seem unnecessary as followup code has potentially infinite retries when polling for status changes. Tested on aopen/dxplplusu, dual-socket P4 Xeon HT model_f2x.

2019-10-28cpu/intel/car: Correctly cache the bootblock with C_ENVIRONMENT_BOOTBLOCKArthur Heymans
With CONFIG_C_ENVIRONMENT_BOOTBLOCK it makes more sense to rely on the size of the bootblock over CONFIG_XIP_ROM_SIZE. To make this work, only powers of 2 are allowed as bootblock size.

2019-09-10AUTHORS: Move src/cpu/intel copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time.

2019-01-13arch/x86: Drop Kconfig AP_SIPI_VECTORKyösti Mälkki
This was used to check romcc-built bootblock and romstage agree about the location of 16-bit entrypoint. There was no need to customize it as bootblock size requirement did not grow. Just check for a fixed location at 4 GiB - 4 KiB. With C_ENVIRONMENT_BOOTBLOCK we can have a proper symbol for the purpose, since it appears in the same compilation unit. It will adjust if C_ENV_BOOTBLOCK_SIZE changes.

2018-06-27cpu/intel/p4-netburst: skip caching rom on model_fxxArthur Heymans
An unidentified combination of speculative reads and branch predictions inside WRPROT-cacheable memory can cause invalidation of cachelines and loss of stack on models based on NetBurst microarchitecture. Therefore disable WRPROT region entirely for all family F models. As an extreme example, just changing the location of a constant string passed to printk() has been witnessed to make a the boot fail early on in romstage.
