ARM: 6458/1: pcmcia: Adds nanoEngine PCMCIA support. This patch adds nanoEngine PCMCIA support, with support for two sockets. In order to have a fully functional pcmcia subsystem in a BSE nanoEngine board you should carefully read this: http://cambuca.ldhs.cetuc.puc-rio.br/nanoengine/ Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Marcelo Roberto Jimenez <mroberto@cpti.cetuc.puc-rio.br> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

ARM: delete struct sys_timer Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.
