From e9bb7f0c6d3f77312970034ca0a63b3df0e3ba8e Mon Sep 17 00:00:00 2001 From: Paul Barker Date: Fri, 8 Sep 2017 10:12:54 +0000 Subject: Support using u-boot with Image format for raspberrypi3-64 For raspberrypi3-64 we need to use the Image or Image.gz format with u-boot instead of the legacy uImage format. We also need to issue the 'booti' command to boot the kernel instead of 'bootm'.
