2010-12-17qlcnic: reset pci function unconditionally during probeRajesh Borundia
Some boot code drivers dont have cleanup routine, so pci function remains in unknown state prior to driver load. So during driver load issue FLR unconditionally. Update driver version to 5.0.14.

2010-12-17x86: avoid high BIOS area when allocating address spaceBjorn Helgaas
This prevents allocation of the last 2MB before 4GB. The experiment described here shows Windows 7 ignoring the last 1MB: https://bugzilla.kernel.org/show_bug.cgi?id=23542#c27 This patch ignores the top 2MB instead of just 1MB because H. Peter Anvin says "There will be ROM at the top of the 32-bit address space; it's a fact of the architecture, and on at least older systems it was common to have a shadow 1 MiB below." Acked-by: H.

2010-12-17x86: avoid E820 regions when allocating address spaceBjorn Helgaas
When we allocate address space, e.g., to assign it to a PCI device, don't allocate anything mentioned in the BIOS E820 memory map. On recent machines (2008 and newer), we assign PCI resources from the windows described by the ACPI PCI host bridge _CRS. On many Dell machines, these windows overlap some E820 reserved areas, e.g., BIOS-e820: 00000000bfe4dc00 - 00000000c0000000 (reserved) pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xdfffffff] If we put devices at 0xbff00000, they don't work, probably because that's really RAM, not I/O memory. This patch prevents that by removing the 0xbfe4dc00-0xbfffffff area from the "available" resource. I'm not very happy with this solution because Windows solves the problem differently (it seems to ignore E820 reserved areas and it allocates top-down instead of bottom-up; details at comment 45 of the bugzilla below). That means we're vulnerable to BIOS defects that Windows would not trip over. For example, if BIOS described a device in ACPI but didn't mention it in E820, Windows would work fine but Linux would fail. Reference: https://bugzilla.kernel.org/show_bug.cgi?id=16228 Acked-by: H.

2010-12-17x86: avoid low BIOS area when allocating address spaceBjorn Helgaas
This implements arch_remove_reservations() so allocate_resource() can avoid any arch-specific reserved areas. This currently just avoids the BIOS area (the first 1MB), but could be used for E820 reserved areas if that turns out to be necessary. We previously avoided this area in pcibios_align_resource(). This patch moves the test from that PCI-specific path to a generic path, so *all* resource allocations will avoid this area. Acked-by: H.

2010-12-17resources: add arch hook for preventing allocation in reserved areasBjorn Helgaas
This adds arch_remove_reservations(), which an arch can implement if it needs to protect part of the address space from allocation. Sometimes that can be done by just putting a region in the resource tree, but there are cases where that doesn't work well. For example, x86 BIOS E820 reservations are not related to devices, so they may overlap part of, all of, or more than a device resource, so they may not end up at the correct spot in the resource tree.

2010-12-17at91: Refactor Stamp9G20 and PControl G20 board fileChristian Glindkamp
As PControl G20 is a carrier board for the Stamp9G20 SoM, some code can be shared. Therefore board-stamp9g20.c is refactored to allow reusing the SoM initialization and board-pcontrol-g20.c is modified to use it.

2010-12-17at91: Fix uhpck clock rate in upll caseRyan Mallon
The uhpck clock should be divided from the utmi clock, not its parent (main). This change is mostly cosmetic as the uhpck rate value is not used anywhere except for the debugfs clock output. Signed-off-by: Ryan Mallon <ryan@bluewatersys.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
