From 4c8d2a633ed22e90c6b1954b10b0f74fd678cb23 Mon Sep 17 00:00:00 2001 From: Richard Genoud Date: Fri, 27 Mar 2026 15:05:08 +0100 Subject: [PATCH] mtd: nand: raw: sunxi_spl: remove user data length reset No need to reset user data length registers in SPL. In SPL, only the first user data length register is used, so we don't need to reset all of them.
