2009-02-17  Rene Schipp von Branitz Nielsen 

        * src/ser_16x5x.c:

        Allow platform code to override the default implementation for

        writing the LCR register and reading the ISR register by using

        the SER_16X5X_WRITE_LCR() and SER_16X5X_READ_ISR() macros.

2008-07-08  Uwe Kindler 

        * cdl/ser_generic_16x5x.cdl

        (CYGINT_IO_SERIAL_GENERIC_16X5X_CHAN_INTPRIO): New interface

        for devices that support per channel interrupt priorities.

        * src/ser_16x5x.c Added int_prio to pc_serial_info type.

        serial_config_port(): uses macro

        CYG_IO_SERIAL_GENERIC_16X5X_CHAN_BAUD_GENERATOR() to get the baud

        devisor from platform if device suppports per channel baudrate

        clocks, pc_serial_init(): Use interrupt priority from int_prio

        data field if device implements

        CYGINT_IO_SERIAL_GENERIC_16X5X_CHAN_INTPRIO

2007-06-22  Alexander Aganichev  

        * cdl/ser_generic_16x5x.cdl

        (CYGPKG_IO_SERIAL_GENERIC_16X5X_XMIT_REQUIRE_PRIME): New option.

        * src/ser_16x5x.c (pc_serial_start_xmit): Allow platform to define

        CYGPKG_IO_SERIAL_GENERIC_16X5X_XMIT_REQUIRE_PRIME if enabling THRE

        interrupt does not generate interrupt unless bytes are posted to the

        FIFO.

2006-11-27  Jonathan Larmour  

        * src/ser_16x5x.c (serial_config_port): Add

        CYGPRI_IO_SERIAL_GENERIC_16X5X_PLF_INIT_HOOK

        in case devices need extra initialization.

2006-02-07  Daniel Néri  

        * cdl/ser_generic_16x5x.cdl

        (CYGNUM_IO_SERIAL_GENERIC_16X5X_FIFO_TX_SIZE): New option.

        * src/ser_16x5x.c (serial_config_port, pc_serial_putc,

        pc_serial_DSR): At TX interrupt, write up to

        CYGNUM_IO_SERIAL_GENERIC_16X5X_FIFO_TX_SIZE bytes to the transmit

        FIFO. This makes better use of the FIFO, since the LSR_THE flag

        resets when the FIFO is non-empty (not when it's full, as this

        code previously assumed).

2003-09-19  Gary Thomas  

        * src/ser_16x5x.c (pc_serial_init):

        Allow platform to define CYG_IO_SERIAL_GENERIC_16X5X_BAUD_GENERATOR

        if the baud rate clock (values) cannot be known at compile time.  In

        this case, the baud rate generator values are provided by platform

        specific code, computed when the device is first initialized.

2003-07-16  Jonathan Larmour  

        * src/ser_16x5x.c (CYG_IO_SERIAL_GENERIC_16X5X_INT_PRIORITY): Add

        so that the calling hardware-specific drivers can override priorities.

        Clarify flow control comment.

2003-03-18  Gary Thomas  

        * src/ser_16x5x.c (pc_serial_set_config):

        Flag for CYG_IO_SET_CONFIG_SERIAL_HW_RX_FLOW_THROTTLE is 32 bits.

2003-02-24  Jonathan Larmour  

        * cdl/ser_generic_16x5x.cdl: Remove irrelevant doc link.

2001-06-19  Jesper Skov  

        * cdl/ser_generic_16x5x.cdl: Only define

        CYGDAT_IO_SERIAL_DEVICE_HEADER when necessary.

2001-06-18  Jonathan Larmour  

        * src/ser_16x5x.c (pc_serial_set_config): Fix length check typo

2001-06-18  Jesper Skov  

        * src/ser_16x5x.c (LCR_PE): Set correct bits (from Boris V. Guzhov)

2001-06-08  Jonathan Larmour  

        * src/ser_16x5x.c: Support FIFOs better by detecting what we've got,

        and only acting if we have a _working_ FIFO.

        Assert on unhandled serial interrupt type.

2001-03-13  Jonathan Larmour  

        * cdl/ser_generic_16x5x.cdl: Rename

        CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO_OPTIONS to

        CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO and make it a boolean. Clarify

        descriptions a little.

        * src/ser_16x5x.c (serial_config_port): Only program FCR if FIFO

        support requested.

        Don't bother with intermediate _fifo_thresh.

        Detabify.

2001-03-13  Jesper Skov  

        * cdl/ser_generic_16x5x.cdl: Removed the default value.

2001-03-09  Julian Smart  

        Removed default value for flavor none in

        CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO_OPTIONS since it

        causes an assert in libcdl

2001-03-05  Jesper Skov  

        2001-02-15  Dave Airlie 

        * src/ser_16x5x.c (serial_config_port): Add support for setting

        a FIFO RX Threshold via CDL

        * cdl/ser_generic_16x5x.cdl: Add support for setting a FIFO

          RX threshold via CDL

2001-01-24  Dave Airlie  

        * src/ser_16x5x.c (pc_serial_DSR): Allow RX timeouts to be interpreted

        as RXs.

2000-12-19   Dave Airlie 

        * src/ser_16x5x.c: Add defines for FIFO control register

        (serial_config_port): Use these defines.

2000-12-07  Jesper Skov  

        * src/ser_16x5x.c (ISR_LS): Corrected value. Spotted by Dave Airlie.

2000-09-18  Jesper Skov  

        * src/ser_16x5x.c: Allow clients to specify register

        stepping. Rename a type. Fix compile error.

2000-09-14  Jesper Skov  

        * src/ser_16x5x.c: Moved ARM/PID driver to provide generic 16x5x

        driver. Rewritten to use HAL IO macros. Still needs some polish

        and configury to properly support all the various target

        controllers that may only have a partial set of the features.

        * cdl/ser_generic_16x5x.cdl: Same.

        * Removed non-PID related ChangeLog entries.

----------------------------------------------------------------------------

2000-08-24  Jonathan Larmour  

        * src/pid_serial_with_ints.c (pid_serial_DSR): Remove accidental

        OVERRUNERR check duplication

2000-08-01  Jonathan Larmour  

        * src/pid_serial_with_ints.c: Throughout, add support for line status

        and modem status callbacks, hardware RTS/CTS and DSR/DTR flow control

        (pid_serial_set_config): Now use keys to make

        more flexible.

        * src/pid_serial.h: Add more line status, interrupt status and modem

        status register definitions

        * cdl/ser_arm_pid.cdl: Implements flow control and line status

        interfaces

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.

2000-06-09  Jesper Skov  

        * src/pid_serial_with_ints.c:

        * src/pid_serial.h:

        Cleaned up defines and made DSR handle all received characters.

        (Dave Airlie (airlied at parthus dot com))

2000-04-11  Hugo Tyson  

        * cdl/ser_arm_pid.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.

2000-01-03  Gary Thomas
