From d2c30190ee69869164c3bfafaed5143b0c316983 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Fri, 2 Aug 2019 07:03:39 -0500 Subject: [PATCH] ARM: da850-evm: Increase environment NOR partition offset The current size allocated to U-Boot is 384k, but U-Boot has grown to 436K which means that saving the environmental variables wipes out part of the U-Boot source and the board ceases to function. Due to the sector and erase size for the NOR part and a desire to not have to change partition sizes often, this patch moves the U-Boot environmental variables to an offset of 1M so saveenv does not brick the board. This patch also sets up MTDIDS and MTDPARTS to clearly show where U-Boot and U-Boot's environmental variables are located.
