移植到WLIT项目的redboot源代码

	* 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  <[e-mail]>

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

1999-10-11  Nick Garnett  <[e-mail]>

	* 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  <[e-mail]>

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

1999-09-28  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

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

1999-08-30  Jesper Skov  <[e-mail]>

	* tests/ser_test_protocol.inl: Added crash information which
	should help track down repeating errors.

1999-08-20  Jesper Skov  <[e-mail]>

	* tests/README: Added.

	* tests/serial3.c: 
	* tests/serial4.c:

1999-08-17  Nick Garnett  <[e-mail]>

	* 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  <[e-mail]>

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

1999-08-12  Nick Garnett  <[e-mail]>

	Imported following changes from development branch:
	
    1999-08-11  Nick Garnett  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

1999-07-28  Jonathan Larmour  <[e-mail]>

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

1999-07-26  Hugo Tyson  <[e-mail]>

	* 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  <[e-mail]>

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

1999-06-27  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

	* src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit
	to avoid compiler warnings.

1999-06-21  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* src/arm/cl7211_serial.c (cl7211_serial_start_xmit): Fix race which
	cause xmitter to get stuck.

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

	Renamed SH platform package to edk7708.

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

1999-05-27  Jonathan Larmour  <[e-mail]>

	* 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

	to death!
