If anyone has any objections, please let me know. ------------------ From: Mark Rutland commit 60349e64a6c65f9f0aa118af711b3c7e137f07ff upstream. Add cputype definitions for C1-Ultra. These will be used for errata detection in subsequent patches. These values can be found in the C1-Ultra TRM: https://developer.arm.com/documentation/108014/0100/ ... in section A.5.1 ("MIDR_EL1, Main ID Register").
