Subject: [PATCH RFC v2 14/14] ARM: debug: move Spear debug to generic PL01x code
Date: Tue, 16 Jul 2013 17:47:13 +0100	[thread overview]
Message-ID: <E1Uz8PB-00048R-F3@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20130716163243.GY21614@n2100.arm.linux.org.uk>

The Spear debug code is a copy of the PL01x debugging code, so rather
than have this pointless code duplication, lets just use the standard
implementation instead.
