Subject: [PATCH 2/4] arm64: imx8mp: Deduplicate DRAM size tables on DH i.MX8MP DHCOM SoM
Date: Wed, 1 Apr 2026 21:15:54 +0200 [thread overview]
Message-ID: <20260401191617.20141-2-marex@nabladev.com> (raw)
In-Reply-To: <20260401191617.20141-1-marex@nabladev.com>
The DRAM size tables are shared by SPL and U-Boot proper, deduplicate
those tables into lpddr4_timing.h . No functional change.
