* arch/tile: parameterize system PLs to support KVM portChris Metcalf2010-10-151-0/+2
| | | | | | | | | While not a port to KVM (yet), this change modifies the kernel to be able to build either at PL1 or at PL2 with a suitable config switch. Pushing up this change avoids handling branch merge issues going forward with the KVM work. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
* arch/tile: various top-level Makefile cleanupsChris Metcalf2010-10-141-2/+15
| | | | | | | | Avoid a compile failure if CONFIG_DEBUG_EXTRA_FLAGS is empty (""); provide an "install" hook as well as a matching archhelp target; and some minor whitespace cleanup. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
* arch/tile: don't validate CROSS_COMPILE needlesslyChris Metcalf2010-08-151-9/+11
| | | | | | | | | | With this change, the arch/tile Makefile will only check for a valid combination of CROSS_COMPILE vs "uname -m" for a few common targets that are typically the ones we get wrong (vmlinux, all, and modules). The change handles the case of an empty "make" goal like "make all". Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org>
* arch/tile: core support for Tilera 32-bit chips.Chris Metcalf2010-06-041-0/+52
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/.
