From 0d1ea05210f3221667f8085cf167f23f336ca0c0 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 11 May 2015 20:50:22 -0300 Subject: wandboard: Switch to SPL support Currently we need to build one U-boot image for each of the wandboard variants: quad, dual-lite and solo. By switching to SPL we can support all these variants with a single binary, which is very convenient. Based on the work from Richard Hu. Tested kernel booting on the three boards.
