From dfce1799e71fd6f36efcea2867b668ab5665e7e1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 13 Nov 2017 18:55:04 -0700 Subject: [PATCH] binman: Add binman support to spl_ram.c SPL supports reading U-Boot from a RAM location. At present this is hard-coded to the U-Boot text base address. Use binman to allow this to come from the image file, if binman is used.
