2003-03-05  Gary Thomas  

        * 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  

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

2002-12-10  Gary Thomas  

        * cdl/ser_quicc_smc.cdl: Only enable devices which exist - as described

        by the HAL/CDL interfaces.

2001-11-30  Jonathan Larmour  

2001-11-29  Christoph Csebits  

        * src/quicc_smc_serial.c:

        aligning buffer to cache lines,

        flushing buffer in cache before flushing the device.

2001-09-10  Jonathan Larmour  

        * cdl/ser_quicc_smc.cdl:

        Fix 234000->230400 typo.

2000-12-22  Björn Stenberg 

        * 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 

        * 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 

2000-12-06  Jonathan Larmour  

        * 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  

        * src/quicc_smc_serial.c (quicc_smc_serial_ISR): Return with

        CYG_ISR_HANDLED (reported by Daniel Lind)

2000-08-01  Jonathan Larmour  

        * src/quicc_smc_serial.c (quicc_smc_serial_set_config): Now use keys

        to make more flexible.

2000-06-22  Hugo Tyson  

        * cdl/.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  

        * 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  

        * 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  

        * 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

2000-03-31  Jesper Skov  

        * cdl/ser_sh_edk7708.cdl: Limit legal baud rate range.

        * src/sh/sh_sci_serial.c: Use baud rate macro instead of hardwired

        constants.

2000-03-07  Jesper Skov  

        * cdl/ser_mips_jmr3904.cdl: Rename devices to match CDL naming.

2000-02-29  Jonathan Larmour  

        * include/serialio.h: Correct baud rate typo: 230400 rather than

        234000. Thanks to Grant Edwards for the report.

2000-02-22  Jesper Skov  

        * tests/ser_test_protocol.inl: Don't use 115200 baud on

        Cogent. Our slower boards can't keep up.

        Added CYGPKG_IO_SERIAL_I386_PC.

        * tests/ser_test_protocol.inl:

        Added support for PC serial line testing.

2000-02-11  Jesper Skov  

        * src/sh/sh_sci_7708.inl (DEVTAB_ENTRY):

        serial_devio => cyg_io_serial_devio

2000-02-10  Jonathan Larmour  

        * src/mn10300/mn10300_serial.c: Ensure all CYG_HAL_MN10300_*

        preprocessor conditionals use the correct CYGPKG_HAL_MN10300_AM3* form

        now.

2000-01-28  Gary Thomas  

        * src/common/tty.c (tty_read): Fix problem with backspace at start

        of line (size must be 'signed' for compare to work).

2000-01-19  Hugo Tyson  

        * 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  

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

        start of line.

2000-01-05  Gary Thomas  

        * 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  

        * include/serial.h: Fix namespace pollution -

        serial_devio => cyg_io_serial_devio

        serial_callbacks => cyg_io_serial_callbacks

        * src/mips/tx3904_serial.c:

1999-12-06  Gary Thomas  

        * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Add loop to handle

        case where an interrupt represents multiple events.

1999-11-19  Gary Thomas  

        * src/powerpc/quicc_smc_serial.c: Channel select for SMC2 was wrong.

1999-11-18  Gary Thomas  

        * include/pkgconf/io_serial.h: Remove mention of 7209/7212.

1999-11-03  John Dallaway  

        * cdl/io_serial.cdl: Define build options.

1999-10-26  Jesper Skov  

        * tests/serial5.c (serial_test): Reduce speed in thumb mode.

        * src/arm/pid_serial.h: Added BE support.

        * src/PKGconf.mak: Use CYGPKG_<> instead of CYG_<> to control what

        needs to be compiled.

1999-10-25  Gary Thomas  

        * 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  

        * tests/ser_test_protocol.inl: Removed AEB rev C change. Was bogus.

1999-10-11  Nick Garnett  

        * tests/ser_test_protocol.inl: Added configury for VR4300 testing.

        * src/mips/vrc4373_serial.c: Added Bi-endian support.

        * include/pkgconf/io_serial.h: Adjusted default baud rates to

        38400.

1999-10-06  Jesper Skov  

        * tests/ser_test_protocol.inl: Run tests on AEB rev C as well.

1999-09-28  Hugo Tyson  

        * 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  

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

1999-08-30  Jesper Skov  

        * tests/ser_test_protocol.inl: Added crash information which

        should help track down repeating errors.

1999-08-20  Jesper Skov  

        * tests/README: Added.

1999-08-18  Jesper Skov  

        * tests/tty1.c:

        * tests/PKGconf.mak:

        Require kernel and kernel C API.

1999-08-17  Nick Garnett  

        * 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  

        * src/PKGconf.mak:

        * src/mn10300/mn10300_serial.c:

        * tests/ser_test_protocol.inl:

        Rename all am32 -> am31

1999-08-12  Nick Garnett  

        Imported following changes from development branch:

    1999-08-11  Nick Garnett  

        * 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  

        * 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  

        * 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  

        * include/pkgconf/io_serial.h: Update descriptions to be more

        generic (CL7x11 instead of CL7211).

1999-07-28  Jonathan Larmour  

        * include/pkgconf/io_serial.h: Correct typos in CDL description

        for serial port 2 driver

1999-07-26  Hugo Tyson  

        * 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  

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

1999-06-27  Gary Thomas  

        * 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.

1999-06-21  Jesper Skov  

        * src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit

        to avoid compiler warnings.

1999-06-21  Gary Thomas  

        * include/pkgconf/io_serial.h: Fix CDL for number of buffers.

        * src/powerpc/quicc_smc_serial.c: Force number of buffers = 1.

1999-06-20  Gary Thomas  

        * include/pkgconf/io_serial.h: Some clean up (removed commented

        obsolete CDL parenting structure).

        Add support for Motorola PowerPC QUICC/SMC.

        * src/arm/cma230_serial.c:

        * src/arm/cl7211_serial.c:

        * src/arm/aeb_serial.c:

        * src/arm/pid_serial_with_ints.c: Use #include to get 'diag_printf()'

        prototypes.

1999-06-17  Gary Thomas  

        * src/arm/cl7211_serial.c (cl7211_serial_start_xmit): Fix race which

        cause xmitter to get stuck.

1999-06-16  Jesper Skov  

        * src/sh/sh_serial.c:          [removed]

        * src/sh/sh_sci_serial.c:      [added]

        * src/sh/sh_sci_7708.inl:      [added]

        * include/pkgconf/io_serial.h:

        * src/PKGconf.mak (EXTRAS_COMPILE):

        * tests/ser_test_protocol.inl:

        Renamed CDL options and restructered driver.

        Fixed CDL typo.

1999-06-04  Jesper Skov  

        * include/pkgconf/io_serial.h: Fixed CDL string for BAUD rate option.

1999-06-04  Gary Thomas  

        * tests/ser_test_protocol.inl: Disable testing at 115200

        for Cogent CMA230 (ARM).

        * src/arm/cma230_serial.c: Fix interrupt for port B.

1999-05-31  Jesper Skov  

        * src/sh/sh_serial.c: Fixed receive interrupts and added handler for

        error interrupts.

1999-05-28  Jesper Skov  

        * io/serial/current/src/PKGconf.mak:

        * io/serial/current/tests/ser_test_protocol.inl:

        * include/pkgconf/io_serial.h:

        Renamed SH platform package to edk7708.

1999-05-27  Jesper Skov  

        * tests/ser_test_protocol.inl: Added ability to change options in

        host software.

1999-05-27  Jonathan Larmour  

        * src/mn10300/mn10300_serial.c (mn10300_serial_config_port):

        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

1999-05-26  Gary Thomas  

        * include/pkgconf/io_serial.h:
