2010-10-15arch/tile: parameterize system PLs to support KVM portChris Metcalf
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>
2010-10-14arch/tile: various top-level Makefile cleanupsChris Metcalf
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>
2010-08-15arch/tile: don't validate CROSS_COMPILE needlesslyChris Metcalf
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>
2010-06-04arch/tile: core support for Tilera 32-bit chips.Chris Metcalf
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/.
