[ARM] 4887/1: i.MXC family: Separate current platform code
From: Juergen Beisert <j.beisert@pengutronix.de> This patch separates the current code into i.MX2 and i.MX3 and modifies the Kconfig files to reflect this separation in the menus. Things happend since last review: - make i.MX3 compile again - fix some structure names to be conform with all the shared/common sources from i.MX1/i.MX2 Previous changes: - stay conform to other Kconfig files (note from Russell King) Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
