Hi!
This is the second resend of the AFS and AFSv2 partition
parsing patches. I already resent them once for v5.0 but
they weren't applied.
If things are not getting anywhere I suppose I will
submit them to ARM SoC or something for v5.2, I suppose
it is a bit of stressful for MTD right now.
Tell me how I can help out (not co-maintenance sorry,
I have too much on my plate already).
Yours,
Linus Walleij

This activates the code for AFS partition parsing on
the Integrator.

This moves the AFS (ARM Firmware Suite) partition parser
for NOR flash down into the parsers subdirectory.

+ARM AFS - ARM Firmware Suite Partitions
+=======================================
+
+The ARM Firmware Suite is a flash partitioning system found on the
+ARM reference designs: Integrator AP, Integrator CP, Versatile AB,
+Versatile PB, the RealView family, Versatile Express and Juno.
+
+Required properties:
+- compatible : (required) must be "arm,arm-firmware-suite"
+
+Example:
+
+flash@0 {
+ partitions {
+ compatible = "arm,arm-firmware-suite";
+ };
+};
