Subject: [PATCH 6/8] ARM64: asm: drop __barebox_arm_head
Date: Mon, 24 Oct 2022 08:57:14 +0200 [thread overview]
Message-ID: <20221024065716.1215046-7-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20221024065716.1215046-1-a.fatoum@pengutronix.de>
Now that we have the common PBL head written in assembly, the 64-bit
inline assembly version remains unused. Drop it.
