        * src/quicc_smc_serial.c (quicc_sxx_serial_init): Handle SCC3 on
        various processors (signal routing differs).

2003-03-28  Gary Thomas  <gary@mlbassoc.com>

        * src/quicc_smc_serial.c: Change how buffers are allocated & aligned
        to a cache line - previous attempt wasted a huge amount of space.

2003-03-23  Gary Thomas  <gary@mlbassoc.com>

        * src/quicc_smc_serial.h: Move common definitions to common
        include file (in HAL).

        * src/quicc_smc_serial.c: 
        * cdl/ser_quicc_smc.cdl: Remove options for baud rate generator
        assignment - use more generic [automatic] support.

2003-03-17  Gary Thomas  <gary@mlbassoc.com>

        * src/quicc_smc_serial.h: 
        * src/quicc_smc_serial.c:

        by Paul Randall <prandall@delta-info.com>

2003-03-05  Gary Thomas  <gary@mlbassoc.com>

        * src/quicc_smc_serial.c: Use common routines to manage CPM/DPRAM
        pointers - much nicer in a multi-driver environment.

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

        * cdl/ser_quicc_smc.cdl: Remove irrelevant doc link.

2002-12-10  Gary Thomas  <gthomas@ecoscentric.com>

        by the HAL/CDL interfaces.

2001-11-30  Jonathan Larmour  <jlarmour@redhat.com>
2001-11-29  Christoph Csebits  <christoph.csebits@frequentis.com>

        * src/quicc_smc_serial.c:
        aligning buffer to cache lines,
        flushing buffer in cache before flushing the device.

2001-09-10  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/ser_quicc_smc.cdl:        
        Fix 234000->230400 typo.


        * src/quicc_smc_serial.c (quicc_smc_serial_init_info): 
        Set quicc going only after most of the other initialization is
        complete - otherwise initializing too early causes some of the
        parameters not to be initialized properly.

2000-12-13  Daniel Lind <daniel.lind@sth.frontec.se>

        * src/quicc_smc_serial.c (quicc_smc_serial_flush): 
        Don't mark a buffer ready unless it has been fully serviced - in
        particular, the interrupt bit must be clear.
        [2000-12-13] committed by Gary Thomas <gthomas@redhat.com>

2000-12-06  Jonathan Larmour  <jlarmour@redhat.com>

        * src/quicc_smc_serial.c: Remove unread tx_enabled variable from
        quicc_smc_serial_info
        Ensure quicc serial interrupt is unmasked in general so that rx works!
        (quicc_smc_serial_start_xmit): Protect better from DSR interruption

2000-10-24  Jonathan Larmour  <jlarmour@redhat.com>

        * src/quicc_smc_serial.c (quicc_smc_serial_ISR): Return with
        CYG_ISR_HANDLED (reported by Daniel Lind)

2000-08-01  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/quicc_smc_serial.c (quicc_smc_serial_set_config): Now use keys
        to make more flexible.

2000-06-22  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/<yournamehere>.cdl: Remove the comment on the empty
        include_files directive; the tools now support this correctly.
        This keeps internal include files internal.

2000-04-11  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/ser_quicc_smc.cdl: Change the parent from CYGPKG_IO_SERIAL
        (which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES
        (which is not...) thus allowing convenient control independent of
        platform.  Also enable all individual devices by default, now, so
        that they can be enabled simply by enabling the above new parent.

2000-04-07  Hugo Tyson  <hmt@cygnus.co.uk>

        * ecos.db: Re-organize device packages.  This is a massive change
        involving deleting all the sources for serial and ethernet drivers
        from where they used to live in
            packages/io/serial/current/src/ARCH/PLATFORM.[ch]
            packages/net/drivers/eth/PLATFORM/current/src/...
        and reinstating them in
            packages/devs/serial/ARCH/PLATFORM/current/src/...
            packages/devs/eth/ARCH/PLATFORM/current/src/...

        All these new packages are properly defined in ecos.db, and are
        all of type "hardware" so that a "target" can grab them.
        
        This directory layout is descriptive of the devices we have right
        now, arch and platform are separate levels just to make it easier
        to navigate in the filesystem and similar to the HAL structure in
        the filesystem.

        It is *not* prescriptive of future work; for example, the mythical
        common highly-portable 16550 serial driver which works on many
        targets would be called "devs/serial/s16550/current", or a serial
        device for a particular board (cogent springs to mind) that can
        work with different CPUs fitted is "devs/serial/cogent/current".

        Changelogs have been preserved and replicated over all the new
        packages, so that no history is lost.

        The contents of individual source files are unchanged; they build
        in just the same emvironment except for a very few cases where the
        config file name changed in this movement.

        Targets in ecos.db have been redefined to bring in all relevant
        hardware packages including net and serial drivers (but the newly
        included packages are only active if their desired parent is
        available.)
        
        The names of CDL options (and their #defines of course) stay the
        same for the serial drivers, for backward compatibility.

        * templates/*/current.ect: these have had CYGPKG_IO_SERIAL added
        rather than it being in (almost) all target definitions.
        
2000-04-05  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/common/tty.c (tty_read): CRLF conversion should use \r\n not \n\r
        (tty_write): Similarly

        * include/ttyio.h: Update CYG_TTY_IN_FLAGS_CRLF and
        CYG_TTY_IN_FLAGS_CRLF to match

2000-02-10  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/mn10300/mn10300_serial.c: Ensure all CYG_HAL_MN10300_*
        preprocessor conditionals use the correct CYGPKG_HAL_MN10300_AM3* form
        now.    

2000-02-03  Jesper Skov  <jskov@redhat.com>

        * src/powerpc/quicc_smc_serial.c: CYG_HAL_POWERPC_x->CYGPKG_...

2000-01-19  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/*.cdl: Add descriptions to a number of options &c which were
        lacking same, also tidied up other typos as noticed en passant.

2000-01-17  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/common/tty.c (tty_read): Avoid echoing "backspace/erase" at

2000-01-05  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/common/serial.c (serial_write): Avoid potential deadlock if
        transmit start actually sends enough characters to signal cond wait.

2000-01-03  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/serial.h: Fix namespace pollution - 
        serial_devio => cyg_io_serial_devio

        * src/arm/pid_serial.h (ISR_RxTO): Define - character received but
        not handled "promptly".

        * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Handle rcv interrupts
        properly (can't ignore them even with TO bit set).

        * src/arm/cl7211_serial.c (cl7211_serial_rx_DSR): Need to handle all
        input (empty input FIFO) otherwise characters get dropped.

1999-10-15  Jesper Skov  <jskov@cygnus.co.uk>

1999-09-28  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): Correct
        value supplied for interrupt priority - it may be unused, but it
        is asserted for range.  Initialize the diagnostic channel if on an
        MBX and if NOT using SMC1 ourselves, to ensure that diag output
        and built-in stubs work correctly; otherwise reset the quicc and
        ignore SMC1 as before.  Fix various warnings, mostly about
        casting/arg-passing/assigning away volatile.

1999-08-31  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Define dummy crash ID.

1999-08-17  Nick Garnett  <nickg@cygnus.co.uk>

        * src/mn10300/mn10300_serial.c: Added a simple implementation of a
        receive FIFO to try and reduce the overhead of receiving bytes.

1999-08-16  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/PKGconf.mak:
        * src/mn10300/mn10300_serial.c:
        * tests/ser_test_protocol.inl:
        Rename all am32 -> am31

1999-08-12  Nick Garnett  <nickg@cygnus.co.uk>

        Imported following changes from development branch:
        
    1999-08-11  Nick Garnett  <nickg@cygnus.co.uk>

        * tests/serial5.c: Modified config test for boards that need a lower
        speed for this test.

        * tests/ser_test_protocol.inl: Removed 14400 baud tests for all
        MN10300 variants. The MN10300 cannot currently do this speed.

        * src/mn10300/mn10300_serial.c: Tidied up the transmit interrupt
        enable/disable code to be variant specific.

        * include/pkgconf/io_serial.h: Undid Jonathan's change, since the
        same options are used for all MN10300 variants.
        
    1999-08-10  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/io_serial.h:
        Reparent CYGPKG_IO_SERIAL_MN10300 from under CYGPKG_HAL_MN10300 to
        CYGPKG_HAL_MN10300_AM32_STDEVAL1 since it's stdeval1 specific

    1999-08-04  Nick Garnett  <nickg@cygnus.co.uk>

        * tests/ser_test_protocol.inl:
        Changed names of MN10300 defines tested. Added AM33 definitions.

        * src/mn10300/mn10300_serial.c:
        Modified driver to work on am33 too. This simply requires some
        alternate definitions of things like register addresses and some
        bits in them plus some extra parameterization of some register
        values.

        * src/PKGconf.mak:
        Added am33 to list of architectures supporting serial lines.
        
1999-07-28  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Update descriptions to be more
        generic (CL7x11 instead of CL7211).

1999-07-28  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Correct typos in CDL description
        for serial port 2 driver

1999-07-26  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/arm/ebsa285_serial.c: New file: device driver for the serial
        device of the Intel StrongARM EBSA-285 evaluation board.

        * include/pkgconf/io_serial.h (CYGPKG_IO_SERIAL_ARM_EBSA285):
        Config for it.

        * src/PKGconf.mak (EXTRAS_COMPILE): Compile it.

        * tests/ser_test_protocol.inl (TEST_SER_DEV): Enable testing of it.

1999-07-08  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl (change_config): Changed implementation.

1999-06-27  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): More robust
        initialization, with data cache disabled.  This seems to fix the
        random failures described below.

        * tests/ser_test_protocol.inl: Add configuration for QUICC/MBX860.
        Added some delays in the configuration change code to make QUICC
        happy [didn't help much although the manual says they are required].

        * src/powerpc/quicc_smc_serial.h (UART_BITRATE): Rewrote macro to 
        match what the Linux driver uses - still doesn't work well, though.

        * src/powerpc/quicc_smc_serial.c: Lots of changes trying to get the
        serial driver working and robust.  At this point it works quite well,
        using the default buffer sizes.  Changing from the defaults seem to
        easily break it though, certainly on input.  Also, changing the baud
        rate seems to not work reliably.

        * src/common/serial.c: Add some tracing/debug info to try and debug
        problems with QUICC serial driver.  These are hard disabled with
        "XX_" prepended to "CYGDBG_DIAG_BUF".  Enabling them gives information
        about how/when data are delivered from the serial driver.

        * include/pkgconf/io_serial.h: Adjust limits and defaults on number and
        size of buffers with values that seem to work.

        Wait for the serial device to become acquiescent before disabling
        it. This prevents cygmon's outgoing characters getting corrupted
        due to transmission being disabled.
        Fix for PR 20047
