1999-04-29  Hugo Tyson  <[e-mail]>

	* src/hal_diag.c (hal_diag_write_char): Only include the code to
	read the '+' from GDB and test for ^C there if not installing the
	default isr to catch these: CYGDBG_HAL_MIPS_INSTALL_CTRL_C_ISR.

1999-04-08  John Dallaway  <[e-mail]>

	* include/pkgconf/mlt_*.*: Use double underscore substitution
	for period character in SECTION_* macro names (PR 19787)

1999-04-08  John Dallaway  <[e-mail]>

	* include/pkgconf/*.ldi: Revised SECTION_* macro arguments to
	avoid padded output sections (PR 19787)

1999-03-24  Nick Garnett  <[e-mail]>

	* include/pkgconf/hal_tx39_jmr3904.h:
	Added some edit-only options for controlling DRAM setup and bus
	timeout detection. These should only be used by experts, so they
	are not presently exported as full config options.

1999-03-23  Nick Garnett  <[e-mail]>

	* src/hal_diag.c (hal_diag_write_char):	Backed off Gary's change.

1999-03-18  Gary Thomas  <[e-mail]>

	* src/hal_diag.c (hal_diag_write_char): Don't disable all interrupts,
	just the ones for the appropriate UART.

1999-03-11  Nick Garnett  <[e-mail]>

	* src/hal_diag.c (hal_diag_write_char):
	Enabled code to process ACK characters and force a breakpoint.
	This is temporary, it needs to use cyg_hal_is_break() and
	cyg_hal_user_break().

1999-03-10  Bart Veer  <[e-mail]>

	* src/hal_diag.c (hal_diag_init):
	Fixed names of symbols used for the frequency option.

1999-03-10  Nick Garnett  <[e-mail]>

	* src/hal_diag.c: 
	* include/pkgconf/hal_tx39_jmr3904.h:
	Removed frequency options and made them more generic to all MIPS
	targets. Changed names where applicable.

1999-03-04  John Dallaway  <[e-mail]>

	* include/pkgconf/*.ldi: give all LDI files unique names so
        that they can co-exist in an eCos build tree (PR 19184)
	* include/pkgconf/*.mlt: give all MLT files unique names so
        that they can co-exist in an eCos build tree (PR 19184)

1999-02-23  Nick Garnett  <[e-mail]>

	* src/hal_diag.c:
	Added support for 66MHz part.
	Disabled handling of GDB O packet acknowledgement, this is now
	done by hal_ctrlc_isr() which also checks for ^C.

	* include/pkgconf/hal_tx39_jmr3904.h:
	Added support for 66MHz part.

1999-02-20  Jonathan Larmour  <[e-mail]>

	Rename CYG_VECTOR_EXTERNAL_2 -> CYGNUM_HAL_INTERRUPT_EXTERNAL_2
	in line with HAL changes
