└─> Cortex-A76/Neoverse-N1: MRC read following MRRC read of specific Generic Timer in AArch32 might give incorrect result
This option adds a workaround for ARM Cortex-A76/Neoverse-N1
errata 1188873 and 1418040.
Affected Cortex-A76/Neoverse-N1 cores (r0p0 to r3p1) could
cause register corruption when accessing the timer registers
from AArch32 userspace.
If unsure, say Y.
