Subject: [PATCH 2/4] video: Assume video to be active if SPL is passing video hand-off
Date: Thu, 22 Feb 2024 18:38:09 +0530 [thread overview]
Message-ID: <20240222130811.3878567-3-devarsht@ti.com> (raw)
In-Reply-To: <20240222130811.3878567-1-devarsht@ti.com>
If SPL is passing video handoff structure to U-boot then it is safe to
assume that SPL has already enabled video and that's why it is passing
video handoff structure to U-boot so that U-boot can preserve the
framebuffer.
