# For ARC hardware revisions prior to 4.10,
# there is a hardware bug causing an ITLB Miss exception even if a

# if an ITLB Miss exception handler does not check whether such an entry
# already exists:
#
# 1. Processor takes an ITLB Miss exception when the entry already exists.
#
# 2. ITLB Miss handler presumes that there is no such entry in TLB, and
# looks for a proper TLB way and set to store the entry.
#
# 3. Because the hardware way selection is pseudo-random, it can return a
# way number that may or may not match the way number of the existing
# entry. If the way number is different, a duplicate TLB entry is created,
# because the MMU checks for duplicate TLB entries only at the time of
# look-up but not at the time of adding entries.
#
# The following ITLB Miss exception is eventually triggered with a cause
# code indicating duplicated TLB entries. This may cause unexpected
# behavior of the software.
#
# This option enables a software workaround for this HW problem.
