*	pci root complex: support for tile architecture	Chris Metcalf	2010-11-24	1	-4/+11
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This change enables PCI root complex support for TILEPro. Unlike TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI support consists of hypervisor upcalls for PIO, DMA, etc. However, the performance is fine for the devices we have tested with so far (1Gb Ethernet, SATA, etc.). The <asm/io.h> header was tweaked to be a little bit more aggressive about disabling attempts to map/unmap IO port space. The hacky <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header and the result was simplified. Both of the latter two headers were preliminary versions not meant for release before now - oh well. There is one quirk for our TILEmpower platform, which accidentally negotiates up to 5GT and needs to be kicked down to 2.5GT. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
*	arch/tile: fix memcpy_fromio()/memcpy_toio() signatures	Chris Metcalf	2010-09-15	1	-4/+4
\| \| \| \| \| \|	This tripped up a driver (not yet committed to git). Fix it now. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
*	arch/tile: core support for Tilera 32-bit chips.	Chris Metcalf	2010-06-04	1	-0/+279
	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/.
