+2000-04-11  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* cdl/ser_powerpc_cogent.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>

+
+2000-01-05  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* src/common/serial.c (serial_write): Avoid potential deadlock if

+
+2000-01-03  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* include/serial.h: Fix namespace pollution -

+
+1999-10-15  Jesper Skov  <jskov@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>

+	* 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:

+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.
+
+1999-06-21  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit
+	to avoid compiler warnings.
+
+1999-06-21  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* 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  <gthomas@cygnus.co.uk>
+
+	* 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  <gthomas@cygnus.co.uk>
+
+	* src/arm/cl7211_serial.c (cl7211_serial_start_xmit): Fix race which
+	cause xmitter to get stuck.
+
+1999-06-16  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* src/sh/sh_serial.c:          [removed]

+	* tests/ser_test_protocol.inl: 
+	Renamed CDL options and restructered driver.
+	Fixed CDL typo.
+	
+1999-06-04  Jesper Skov  <jskov@cygnus.co.uk>

+
+	* tests/ser_test_protocol.inl: Disable testing at 115200
+	for Cogent CMA230 (ARM).

+
+1999-05-31  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* src/sh/sh_serial.c: Fixed receive interrupts and added handler for
+	error interrupts.
+
+1999-05-28  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* 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  <jskov@cygnus.co.uk>
+
+	* tests/ser_test_protocol.inl: Added ability to change options in
+	host software.
+
+1999-05-27  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+	* 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
+

+	Added extra test to avoid initializing serial 2 when CYGMON is
+	present.
+	Include hal_intr.h explicitly for use in non-kernel
+	configurations.
+
+	* src/common/serial.c:
+	Added extra test before calls to cyg_drv_cond_wait() to avoid race
+	condition. This is not, however, a complete solution to this
+	problem. A better solution will be forthcoming.
+
+	* include/serial.h:
+	Changed include files used to permit non-kernel configurations to
+	be built.

+1999-03-05  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+       * src/mn10300/mn10300_serial.c:
+       Change CYG_VECTOR_* to CYGNUM_HAL_INTERRUPT_* to get it to compile!
+
+1999-03-05  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* src/powerpc/cogent_serial_with_ints.c (cogent_serial_config_port): 
+	Fix renaming of interrupt vectors.
