This change improves and cleans up the tile console. - We enable HVC_IRQ support on tilegx, with the addition of a new Tilera hypervisor API for tilegx to allow a console IPI. If IPI support is not available we fall back to the previous polling mode. - We simplify the earlyprintk code to use CON_BOOT and eliminate some of the other supporting earlyprintk code. - A new tile_console_write() primitive is used to send output to the console and is factored out of the hvc_tile driver. This lets us support a "sim_console" boot argument to allow using simulator hooks to send output to the "console" as a slightly faster alternative to emulating the hardware more directly.

The hardwall drain code was not properly implemented for tilegx, just tilepro, so you couldn't reliably restart an application that made use of the udn. In addition, the code was only applicable to the udn (user dynamic network). On tilegx there is a second user network that is available (the "idn"), and there is support for having I/O shims deliver user-level interrupts to applications ("ipi") which functions in a very similar way to the inter-core permissions used for udn/idn. So this change also generalizes the code from supporting just the udn to supports udn/idn/ipi on tilegx. By default we now use /dev/hardwall/{udn,idn,ipi} with separate minor numbers for the three devices. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.
