* Implemented _RemoveTransferFromEndpoint
* Reworked _AppendChainDescriptorsToEndpoint as now every endpoint has (must have) a dummy descriptor
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23741 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed _SubmitControlRequest in order to use _AppendChainDescriptorsToEndpoint
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23734 a95241bf-73f2-0310-859d-f6bbb57e9c96
* renamed trasfer_data memeber top to first_descriptor
* added data_descriptor member to transfer_data (useful for control transfer)

so in the first place)
* Renamed local variable descriptor to current in the finisher thread
* Using next_done_descriptor instead of next_logical_descriptor, as the latest
is used to keep track of all descriptors that belongs to the transfer
* Added _UnlinkTransfer private method
* Implemented _FreeDescriptorChain
* Moved endpoint pointer from the ohci_general_td structur to the transfer_data_s
structure, ad the ohci_general_td has already a transfer_data_s pointer which can
be used to the endpoint pointer reducing ridundancy.

* Continue working in the _FinishTransfer thread
* added next_done_descriptor in ohci_[general|isochronous]_td structure in order to handle
collisions.
* added next_logical_descriptor to ohci_isochronous_td structure

of the descriptor from its physical address returned by the controller.
NOTE: As stated in the commented code, when the controller has finished processing
some descriptors, it returns the first element physical address of an heterogeneous list
(general + isochronous) and there is not way to tell the descriptor type.
This solution, which implementes two hash tables (one for generic descriptors and
one for isochronous) is the one adopted from *BSD.
If somebody has better idea, please let me know. :)

functions are needed to pass data back to the user space buffer.
* Fixed Jamfile
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22982 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added _SubmitControlRequest (almost implemented), _LinkDescriptors, _WriteDescriptorChain (basically copied from EHCI, and UHCI)
* Renamed ohci_general_descriptor to ohci_general_td, and ohci_isochronous_descriptor to ohci_isochronous_td
* Finished _CreateGeneralDescriptor and _FreeGeneralDescriptor
* Added buffer_size member to ohci_general_td instead and removed last_logical_byte_address as it looked unnecessary
* minor clean up
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22968 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Reworking the interrupts endpoints tree parts
* Added spin_locker, semaphore, finisher thread and interrupt handler (not implemented)
* Made fInterruptEndpoints allocation dynamic instead of static
* Fixed Start method (it should be correct now)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22927 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Rewrote _AllocateEndpoint
* More work in the constructor
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22873 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed IOC bit on last TD. To find out whether the TD removed is the
last one of a transfer it simply iterate through every transfer submitted. Not the best
solution, but should be ok for now. Improvements will be made when there will be some driver to test it with.
* Clean up
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22545 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renaming, fixing coding guidelines
* Re-writing AddTo method
* Removing ohci_software.h file (its content has been moved to ohci.h) but it will probably be deleted in the future.
