* [MIPS] Alchemy: Fix USB initialization.Florian Fainelli2007-10-094-10/+10
| | | | | | | | | | | | | | | | | | | | | This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten.

* Longhaul: add auto enabled "revid_errata" optionRafal Bilski2007-10-081-3/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VIA C3 Ezra-T has RevisionID equal to 1, but it needs RevisionKey to be 0 or CPU will ignore new frequency and will continue to work at old frequency. New "revid_errata" option will force RevisionKey to be set to 0, whatever RevisionID is. Additionaly "Longhaul" will not silently ignore unsuccessful transition. It will try to check if "revid_errata" or "disable_acpi_c3" options need to be enabled for this processor/system. Same for Longhaul ver. 2 support. It will be disabled if none of above options will work. Best case scenario (with patch apllied and v2 enabled): longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v2 supported. longhaul: Using northbridge support. longhaul: VRM 8.5 longhaul: Max VID=1.350 Min VID=1.050, 13 possible voltage scales longhaul: f: 300000 kHz, index: 0, vid: 1050 mV [...] longhaul: Voltage scaling enabled. Worst case scenario: longhaul: VIA C3 'Ezra-T' [C5M] CPU detected. Powersaver supported. longhaul: Using northbridge support. longhaul: Using ACPI support. longhaul: VRM 8.5 longhaul: Claims to support voltage scaling but min & max are both 1.250. Voltage scaling disabled longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Disabling ACPI C3 support. longhaul: Disabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI-E slot on T1000 connects directly to the Fire PCI chip with no intervening bridges visible in the OBP tree. Unfortunately the bus numbering of the device in that slot is different (2) from the PCI host controller (0), and thus the pci_bus_{read,write}_config_*() calls don't work out. Complicating things further the Fire PCI controller has no config space it responds to either. For now treat this case specially so that devices in the slot work. Longer term we need to perhaps cons up a dummy bridge between the Fire and the PCI-E slot so that the bus hierarchy is complete inside of the kernel and thus the bus numbering all works out right.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For the case where the source is not aligned modulo 8 we don't use load-twins to suck the data in and this kills performance since normal loads allocate in the L1 cache (unlike load-twin) and thus big memcpys swipe the entire L1 D-cache. We need to allocate a register window to implement this properly, but that actually simplifies a lot of things as a nice side-effect. Signed-off-by: David S. Miller <davem@davemloft.net>
