changelog

Intel XScale PXA255 引导Linux的Redboot 版bootloader源代码！

2000-10-12  Jesper Skov  <[e-mail]>

	* src/cma230_serial.c: Fix typo.

	* cdl/ser_arm_cma230.cdl: Testing parameters moved here.

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

	* src/cma230_serial.c (cma230_serial_set_config): Now use keys to make
	more flexible.

2000-06-22  Hugo Tyson  <[e-mail]>

	* cdl/<yournamehere>.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  <[e-mail]>

	* cdl/ser_arm_cma230.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  <[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.
	
2000-04-05  Jonathan Larmour  <[e-mail]>

	* 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  <[e-mail]>

	* cdl/ser_sh_edk7708.cdl: Limit legal baud rate range.
	* src/sh/sh_sci_serial.c: Use baud rate macro instead of hardwired
	constants.

2000-02-28  Gary Thomas  <[e-mail]>

	* src/powerpc/quicc_smc_serial.c: Use standard 'diag_dump_buf()'.

2000-02-28  Jesper Skov  <[e-mail]>

	* tests/ser_test_protocol.inl: Allow 115200 baud on Cogent
	again. Fixed interrupt problem.

2000-02-22  Jesper Skov  <[e-mail]>

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

	now.

	start of line.

	transmit start actually sends enough characters to signal cond wait.

2000-01-03  Gary Thomas  <[e-mail]>

	* include/serial.h: Fix namespace pollution - 
	serial_devio => cyg_io_serial_devio
	serial_callbacks => cyg_io_serial_callbacks

	* src/mips/vrc4373_serial.c: 
	* src/mn10300/mn10300_serial.c: 
	* src/powerpc/quicc_smc_serial.c:

1999-12-06  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

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

1999-11-18  Gary Thomas  <[e-mail]>

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

1999-11-03  John Dallaway  <[e-mail]>

	* cdl/io_serial.cdl: Define build options.

1999-10-26  Jesper Skov  <[e-mail]>
	* 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  <[e-mail]>

	* 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  <[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.

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]>

	should help track down repeating errors.

	* tests/README: Added.

1999-08-18  Jesper Skov  <[e-mail]>

	* tests/tty1.c: 
	* tests/tty2.c: 
	* tests/serial1.c: 
	* tests/serial2.c: 
	* tests/serial3.c: 
	* tests/serial4.c: 
	* tests/serial5.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.
