ARM: cns3xxx: Add basic support for Cavium Networks CNS3xxx processors This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore (ARMv6) dual-core processors. Note that SMP is not yet supported, as well as many peripheral devices. Support for these features will be added later. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>

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.

ARM: cns3xxx: Add support for L2 Cache Controller CNS3xxx SOCs have L310-compatible cache controller, so let's use it. With this patch benchmarking with 'gzip' shows that performance is doubled, and I'm still able to boot full-fledged userland over NFS (using PCIe NIC), so the support should be pretty robust. p.s. While CNS3xxx reports that it has PL310, it still needs to wait on cache line operations, so we should not select 'CACHE_PL310', which is a micro-optimization that removes these waits for v7 CPUs. Someday we'd better rename CACHE_PL310 Kconfig option into NO_CACHE_WAIT or something less ambiguous. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>
