From ff2379662c4a0bc5f462a568ab5dd43dd0e0d029 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 24 Aug 2023 17:24:37 +0100 Subject: [PATCH] uboot-mediatek: increase max. memory regions on mt7988-rfb WED requires a bunch of additional reserved memory regions. As U-Boot's LMB allocator defaults to a maximum of only 8 regions, this currently makes using WED impossible. Raise LMB_MAX_REGIONS to 64 just like for all other MediaTek boards with a SoC supporting WED.
