Rename OEA to AIM. The former means nothing as it applies to all processors (it's the PowerPC Operating Environment Architecture). AIM designates the processors made by the Apple-IBM-Motorola alliance and those we typically support. While here, remove the NetBSD option IPKDB. It's not an option used by us. Also, PPC_HAVE_FPU is not used by us either. Remove that too. Obtained from: Juniper, Semihalf

Let us manage differences of Book-E PowerPC variations i.e. vendor / implementation specific vs. the common architecture definition. Bring PPC4XX defines (PSL, SPR, TLB). Note the new definitions under BOOKE_PPC4XX are not used in the code yet. This change set is not supposed to affect existing E500 support, it's just another reorg step before bringing support for E500mc, E5500 and PPC465. Obtained from: AppliedMicro, Freescale, Semihalf

Import support for the Sony Playstation 3 using the OtherOS feature available on firmwares 3.15 and earlier. Caveats: Support for the internal SATA controller is currently missing, as is support for framebuffer resolutions other than 720x480. These deficiencies will be remedied soon. Special thanks to Peter Grehan for providing the hardware that made this port possible, and thanks to Geoff Levand of Sony Computer Entertainment for advice on the LV1 hypervisor.

Add three new drivers for fan control and temperature reading on the PowerMac7,2. - The fcu driver lets us read and write the fan RPMs for all fans in the PowerMac7,2. This driver is PowerMac specific. - The ds1775 is a driver to read the temperature for the drive bay sensor. - The max6690 is another driver to read temperatures. Here it is used to read the inlet, the backside and the U3 heatsink temperature. An additional driver, the ad7417, will follow later. Thanks to nwhitehorn for guiding me through this driver development. Approved by: nwhitehorn (mentor)

Chelsio T4/T5 VF driver. The cxgbev/cxlv driver supports Virtual Function devices for Chelsio T4 and T4 adapters. The VF devices share most of their code with the existing PF4 driver (cxgbe/cxl) and as such the VF device driver currently depends on the PF4 driver. Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf PCI device driver that attaches to the VF device. It then creates child cxgbev/cxlv devices representing ports assigned to the VF. By default, the PF driver assigns a single port to each VF. t4vf_hw.c contains VF-specific routines from the shared code used to fetch VF-specific parameters from the firmware. t4_vf.c contains the VF-specific PCI device driver and includes its own attach routine. VF devices are required to use a different firmware request when transmitting packets (which in turn requires a different CPL message to encapsulate messages). This alternate firmware request does not permit chaining multiple packets in a single message, so each packet results in a firmware request. In addition, the different CPL message requires more detailed information when enabling hardware checksums, so parse_pkt() on VF devices must examine L2 and L3 headers for all packets (not just TSO packets) for VF devices. Finally, L2 checksums on non-UDP/non-TCP packets do not work reliably (the firmware trashes the IPv4 fragment field), so IPv4 checksums for such packets are calculated in software. Most of the other changes in the non-VF-specific code are to expose various variables and functions private to the PF driver so that they can be used by the VF driver. Note that a limited subset of cxgbetool functions are supported on VF devices including register dumps, scheduler classes, and clearing of statistics. In addition, TOE is not supported on VF devices, only for the PF interfaces.

Redefine bus_space_tag_t on PowerPC from a 32-bit integral to a pointer to struct bus_space. The structure contains function pointers that do the actual bus space access. The reason for this change is that previously all bus space accesses were little endian (i.e. had an explicit byte-swap for multi-byte accesses), because all busses on Macs are little endian. The upcoming support for Book E, and in particular the E500 core, requires support for big-endian busses because all embedded peripherals are in the native byte-order. With this change, there's no distinction between I/O port space and memory mapped I/O. PowerPC doesn't have I/O port space. Busses assign tags based on the byte-order only. For that purpose, two global structures exist (bs_be_tag and bs_le_tag), of which the address can be taken to get a valid tag. Obtained from: Juniper, Semihalf
