基于ecos的redboot

2001-08-15  Gary Thomas  <[e-mail]>

	* tests/ser_test_protocol.inl: Change NONE in 'cyg_verbosity_level_t'
	to be _NONE [unused] to avoid name clash with <kernel/kapi.h>.

2000-12-08  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c: Fix CYGOPT_IO_SERIAL_FLOW_CONTROL_HW ->
	CYGOPT_IO_SERIAL_SUPPORT_LINE_STATUS typo when declaring callbacks
	Thanks to Brian Danilko for reporting.

2000-11-22  Jesper Skov  <[e-mail]>

	* src/common/serial.c: Changed #ifdef to #if used on an interface
	option.

2000-11-06  Jonathan Larmour  <[e-mail]>

	* src/common/tty.c (tty_write): Check buffer size appropriately
	since when doing \r\n expansion "size" may have been double
	incremented as a result.
	Thanks to Alex Mathews of Crosstor for the fix.

2000-10-20  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c: Include cyg/infra/cyg_ass.h for assertion
	support since we have assertions here!

	device driver CDL.

	* src/common/serial.c (serial_rcv_char): Register overruns.
	
	* src/common/serial.c: Made block request functions return cause
	of failure. Necessary for the device driver to be able to
	fall-back to other transfer method efficiently.
	* include/serial.h: Added enum with failure types.

2000-10-03  Jesper Skov  <[e-mail]>

	non-default flow control config.

2000-09-27  Jesper Skov  <[e-mail]>

	* src/common/serial.c (serial_data_rcv_done,
	serial_data_xmt_done): Buffer pointers updated in _done instead of

2000-09-18  Jesper Skov  <[e-mail]>

	* cdl/io_serial.cdl: Added interfaces to allow test tweaking.

2000-09-06  Jesper Skov  <[e-mail]>

	serial driver reorg.

2000-08-09  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c (serial_indicate_status): Treat flow control
	case conditionally

2000-08-08  Jonathan Larmour  <[e-mail]>

	flow control overall default off)

	* tests/flow1.c (cyg_start): Fix N_A_MSG -> NA_MSG typo
	* tests/flow2.c (cyg_start): Ditto

2000-08-03  Jonathan Larmour  <[e-mail]>

	* src/common/serial.c (serial_data_xmt_req): Update cbuf->nb
	(serial_data_rcv_req): Update cbuf->nb

2000-08-01  Jonathan Larmour  <[e-mail]>

	* cdl/io_serial.cdl: Add support for line status queries,
	software flow control, hardware flow control and POSIX termios
	* include/serial.h: Likewise. Also change prototype for set_config
	hardware operations to use keys to be more flexible.
	* include/serialio.h: Add lots of types and constants to support
	new line status and flow control config key queries
	
	* src/common/haldiag.c (haldiag_set_config): Use keys to be more
	flexible.

	* src/common/serial.c: Many changes to support software/hardware
	flow control (with low and high water points), line status and
	fix some omissions with select. Also fix bugs in block transfer
	functions resulting from EL/IX merge.

	* tests/flow1.c, tests/flow2.c: New tests for flow control

	* cdl/termios.cdl: Add to configure termios
	* src/termios.c: Add new POSIX Termios API

2000-06-19  Nick Garnett  <[e-mail]>

	* include/serial.h:
	* src/common/serial.c:
	Added nb field to cbuf_t structure. This keeps track of the number of
	bytes currently in the buffer. Without this counter, there is no
	way to distinguish a totally full buffer from one that is totally
	empty, since in both cases put==get.

2000-06-15  Nick Garnett  <[e-mail]>

	* include/serial.h: Added selinfo field to cbuf structure when
	select support is enabled.

	* src/common/serial.c:
	* src/common/tty.c:

2000-05-01  Jesper Skov  <[e-mail]>

	* src/common/serial.c: Added non-blocking config and operation for
	read/write calls.

	transfer interface.

	* src/PKGconf.mak: remove; it's obsolete.

2000-04-13  Gary Thomas  <[e-mail]>

	* src/common/serial.c (serial_write): Make safer - only call
	'start_xmit' with DSRs disabled.

2000-04-11  Hugo Tyson  <[e-mail]>

	* cdl/io_serial.cdl (CYGPKG_IO_SERIAL_DEVICES): New package which
	is a container and control for the real device drivers.

2000-04-11  Jesper Skov  <[e-mail]>

	* cdl/io_serial.cdl: Bad hack to build separate test.
	* tests/serial_echo.c: Added.

2000-04-11  Hugo Tyson  <[e-mail]>

	* cdl/ser_.... (driver-specific cdl files):
	Remove all these; they are no longer needed following the change
	below.  They do exist in devs/serial/ARCH/PLATFORM/VERSION/cdl/
	directories various instead.

2000-04-07  Hugo Tyson  <[e-mail]>

	* 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.
	
2000-04-07  Jonathan Larmour  <[e-mail]>

	* src/common/tty.c (tty_read): Correct handling of modes with newlines

2000-04-05  Jonathan Larmour  <[e-mail]>

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