From: Ross Burton <[email protected]>
Hi,
I've now sent a first draft of a fragmented genericarm64 configuration to
linux-yocto@[1] and this now uses it. I've boot tested it on a BeaglePlay:
there's still plenty to be improved but it's a start.
This can't be merged as-is as the SRCREV for the genericarm64 machine is
wrong, which is why this is a RFC. When Bruce merges, I can update.
Ross

+SystemReady Arm Platforms
+=========================
+
+The genericarm64 MACHINE is designed to work on standard SystemReady IR
+compliant boards with preinstalled firmware.
+
+The genericarm64 MACHINE is currently tested on the following platforms:
+
+ * Texas Instruments BeaglePlay
+
+The images built are EFI bootable disk images and can be written directly to a
