From e6f8cf622318e65a00a5322509707f3f25cef68e Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Tue, 2 Nov 2021 23:35:32 +0100 Subject: [PATCH] uboot-lantiq: danube: fix SPL boot On danube we only have 0x6800 bytes of usable SRAM. Everything behind can't be written to and a SPL u-boot locks up during boot. Since it's a hard to debug issue and took me more than two years to fix it, I consider it worth to include fix albeit SPL u-boots are not build in OpenWrt. I faced the issue while trying to shrink the u-boot to 64K since some boards only have an u-boot partition of that size from the days ifx-uboot was used.
