Subject: [PATCH V6 1/3] tools: header: arm64: Replace TCR_NFD[0|1] with TCR_EL1_NFD[0|1]
Date: Mon, 13 Oct 2025 10:59:43 +0530 [thread overview]
Message-ID: <20251013052945.2197190-2-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20251013052945.2197190-1-anshuman.khandual@arm.com>
Replace TCR_NFD[0|1] (used in TCR_CLEAR_FUJITSU_ERRATUM_010001) with field
definitions which are available in tool sysreg format. Helps in completely
dropping off the adhoc TCR_NFD[0|1] macros later.
