From e82c624d7cd0640da789ecb0d6906db491003e2d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 8 Dec 2019 17:40:12 -0700 Subject: spl: Add methods to find the position/size of next phase Binman supports writing the position and size of U-Boot proper and SPL into the previous phase of U-Boot. This allows the next phase to be easily located and loaded. Add functions to return these useful values, along with symbols to allow TPL to load SPL.
