 The current target platforms are Pine64, Raspberry Pi 3 and Opteron A1100.
 </p>
 
+<p>
+The Pine64 currently requires an image based on a non-redistributable
+boot0 file from Allwinner to be installed on the system disk.
+This will hopefully be resolved by a replacement in a future U-Boot
+release.  The install media does not include these boot images or
+a Pine64 device tree.
+</p>
+
+<p>
+The Raspberry Pi 3 requires closed but redistributable files on the
+system disk to load into the VC4 GPU which starts the ARM cores.
+The boot ROM will only try to load these files off an SD card unless a
+special config.txt value is set to irreversibly enable USB boot mode.
+These files are present in the install media but there is no driver
+for SD/MMC yet so a USB disk drive and manual steps are required.
+</p>
+
+<p>
+Opteron A1100 machines on the other hand come with a UEFI firmware
+that includes a device tree and can boot off SATA or USB devices without
+board specific boot files on the system disk.
