2003-02-25  Jonathan Larmour  <jifl@eCosCentric.com>

        * doc/usbs_sa11x0.sgml: Declare as <part> not <reference> to get
        correct TOC numbering.

2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/usbs_sa11x0.cdl: Fix doc link.

        * doc/usbs_sa11x0.sgml: Comment out DOCTYPE for now to allow building
        with standard doc build.
        Add an enclosing <reference> so it's structured better with standard
        doc build.

2002-02-11  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Add a handler for the SET_INTERFACE standard control message.
        This should not be needed, but appears to avoid hardware problems
        when a compliance testing program sends certain requests. Also
        improve the handling of halted endpoints since the hardware
        does not allow transfers to be aborted.

2002-01-23  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Add missing assertions for non-NULL buffers
        Try to improve the behaviour when the host sends data before
        the target is ready. The hardware is not capable of handling
        this situation, but some recovery is possible some of the time. 

2001-09-14  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Update support for USB testing

2001-08-06  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Add initial support for USB testing.

2001-05-21  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c (usbs_sa11x0_ep2_dsr):
        Fix the boundary condition where the transmission is an exact
        multiple of 64 bytes. ep2_process_packet() already did the
        right thing but was not getting called.
        Also, some cosmetic changes to the receive code for the
        same boundary condition. These actually have no effect
        because of the hardware, but may be useful for other
        people writing USB device drivers.

2001-04-05  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c (usbs_sa11x0_ep0_fill_fifo):
        Set the DATA_END and IN_READY bits in one operation.
        This seems to avoid problems when the target needs to send
        back a zero-length control packet.

2001-02-02  Bart Veer  <bartv@redhat.com>

        * cdl/usbs_sa11x0.cdl:
        Add doc property to the html

        * doc/usbs_sa11x0.sgml, devs-usbs-sa11x0.html:
        Incorporate changes from docs department, regenerate html

2001-01-25  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0_data.cxx:
        * cdl/usbs_sa11x0.cdl:
        Devtab entries were never actually being built - and did not
        build... 

        * cdl/usbs_sa11x0.cdl:
        Sort out the dependencies for minimal environments such as
        RedBoot. 

2001-01-24  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Invoke additional platform-specific initialization, if defined
        via <cyg/hal/hal_io.h> and CYGBLD_HAL_PLATFORM_IO_H

2001-01-22  Bart Veer  <bartv@redhat.com>

        * doc/usbs_sa11x0.sgml, doc/makefile:
        Added documentation.

2001-01-16  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Make sure that the resume interrupt source is enabled,
        even when the USB bus is not suspended. For some reason
        this makes it possible to disconnect and reconnect.
        
2001-01-16  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Use the HAL macros for virtual->physical address translation
        Update poll() and start() to match the documentation
        Fix the handling of control messages affecting endpoints 1 and 2
        if those endpoints are not currently configured.


2001-01-02  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Change ep2_tx_packet() to start the DMA operation after the
        UDC packet-complete bit has been set. This avoids a very high
        error rate. Add some scheduler locking to eliminate a resulting
        race condition, and sort out the error handling to match.
        Comment out some assertions relating to spurious interrupts, which
        have been observed. Instead the code now recovers from these.

2000-12-15  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Add debug code for tracking stats and simulating failures.
        Change the EP1 code to switch between DMA channels A and B as
        required, rather than always using channel A. This is more robust
        and was needed for the failure simulation.
        
        Make the ep1 packet processing code robust in case an unexpected
        failure occurs during its invocation. It is not clear how this
        can ever happen, but on a couple of occasions it did and caused an
        infinite loop.

2000-11-30  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Fix DMA_CONTROL_CLEAR_ALL constant, it was ignoring START_B
        In ep2_init(), separate out the fifo write and the IN_SIZE
        write to avoid a hardware problem.

2000-11-29  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Disable some debugging features and add retries when manipulating
        certain DMA registers - needed with some Silicon revisions.

2000-11-28  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        More rewriting, plus implementing the endpoint halt support.

2000-11-24  Bart Veer  <bartv@redhat.com>

        * src/usbs_sa11x0.c:
        Clean up some of the debugging.
        Largely rewrite the endpoint 2 support to try and get it working
        Transmit a runt packet during initialization to work around
        hardware problem.

2000-11-22  Bart Veer  <bartv@redhat.com>

        * include/usbs_sa11x0.h: Fix nested #include protection

2000-11-21  Bart Veer  <bartv@redhat.com>

        * First check-in of eCos USB support.
