From bbaeb7ac2200c6505a76f1bf5ba85cfe58fb750b Mon Sep 17 00:00:00 2001 From: "Eugen.Hristev@microchip.com" Date: Wed, 28 Nov 2018 09:33:43 +0000 Subject: ARM: at91: lds: add test for SPL binary size and bss size Add test for the SPL binary size and the bss section size. This will throw an error at build time if the SPL sections do not fit in the designated RAM area, thus avoiding oversizing the SPL. Based on original work by Wenyou Yang.
