[PATCH] UBUNTU: [Config] disable ARCH_TANGO

[Paolo Pisati]

BugLink: https://bugs.launchpad.net/bugs/1787945

Impact:

The TANGO platform (an embedded soc used in home entertainment, connectivity and
control devices) is enabled by default in the generic arm kernel. During kernel
bootup, the tango platform blindly registers its pm ops in
arch/arm/mach-tango/pm.c via initcalls() (without checking whether it's actually
running on the correspondent hardware) and this causes OOPS during suspend on
tegra platforms since the tango pm .enter function directly pokes the underlying
hardware.

Given the narrow scope of this SOC, i propose to disable support for the TANGO
arch.

Fix:

Apply the attached patch and recompile.

How to test:

Suspend the tegra board and chek that it worked.
