From c27efde68dfd7fd2da364d556d586495e78d3396 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 20 Aug 2013 08:53:43 -0400 Subject: am33xx: Correct and expand comments on CONFIG_SPL_MAX_SIZE We had been allowing the max size to be larger than actually allowed by the ROM. Expand the commentary here to explain why we set these locations.
