Subject: [PATCH 2/2] riscv: convert the t-head pbmt errata to use the __nops macro
Date: Tue, 7 Jun 2022 16:30:59 +0200 [thread overview]
Message-ID: <20220607143059.1054074-3-heiko@sntech.de> (raw)
In-Reply-To: <20220607143059.1054074-1-heiko@sntech.de>
Instead of manually inserting the list of nops, use the recently
introduced __nops(n) macro to make everything more readable.
