https://review.coreboot.org/c/coreboot/+/44922/1//COMMIT_MSG@10 PS1, Line 10: correct jump instruction.
Please add on what boards/chipsets this caused problems. […]
this would have broken any real hardware using cpus before the pentium4. this includes anything using the i440bx code, such as the p2b mainboard family, as well as the i440lx code i am working on.
qemu i440fx likely still worked because its current default cpu emulation supports the clcache instruction, despite that being anachronistic for that chipset.
