Subject: [PATCH 9/9] arm: socfpga: agilex5: add explicit unreachable after TF-A load
Date: Thu, 16 Apr 2026 11:48:13 +0200 [thread overview]
Message-ID: <20260416-socfpga-agilex5-sdram-v1-9-07556aa7219f@pengutronix.de> (raw)
In-Reply-To: <20260416-socfpga-agilex5-sdram-v1-0-07556aa7219f@pengutronix.de>
While agilex5_load_and_start_image_via_tfa() already contains a
__builtin_unreachable(), it's not obvious that the function doesn't
return when looking at agilex5_barebox_entry().
Add __builtin_unreachable() to help the reader.
