2000-11-27  Gary Thomas  <[e-mail]>

	* src/hal_diag.c (init_channel): UART setup required on Brutus as well.

2000-11-21  Gary Thomas  <[e-mail]>

	* src/hal_diag.c (init_channel): Disable broken uart setups on platforms
	other than the SA1110MM, since this code seems to be somewhat broken.

2000-10-25  Drew Moseley  <[e-mail]>

	* src/hal_diag.c: Added UART1 support for SA1100 targets.

	* include/hal_sa11x0.h: Added GPIO bit definitions.

2000-07-14  Gary Thomas  <[e-mail]>

	* include/hal_diag.h (HAL_DELAY_US): Define.

	* src/sa11x0_misc.c (hal_delay_us): New function.  Used to 
	provide timers/delays in non-kernel systems.

2000-07-05  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: 
	* src/hal_diag.c:
	Cleaned up channel options.
	
	* src/hal_diag.c: Use per-channel structure instead of code cruft.

2000-06-30  Jesper Skov  <[e-mail]>

	* src/hal_diag.c: calling i/f macro changes.

2000-06-28  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: 
	* include/plf_stub.h:
	* src/plf_stub.c: [deleted]
	Stub uses vector table for all IO.
	
	* src/sa11x0_misc.c: Fix compiler warning.

2000-06-27  Jesper Skov  <[e-mail]>

	* src/hal_diag.c: Some fixes and code layout changes (Gary
	Thomas).

	* src/hal_diag.c:
	* include/hal_diag.h:
	* include/hal_sa11x0.h:
	Changed to initialize all procs tables. Added timeout getc, and
	proper debug channel switch behavior.

2000-06-24  Gary Thomas  <[e-mail]>

	* src/sa11x0_misc.c (hal_clock_reset): Add code to compensate for
	clock drift since this hardware does not reset on interrupts.
	(hal_clock_read): Also adjust the value returned here for same reason.

2000-06-22  Gary Thomas  <[e-mail]>

	* src/hal_diag.c (hal_diag_write_char): 
	Fix typo: CYGINT_HAL_GDB_PORT_VECTOR to be CYGHWR_HAL_GDB_PORT_VECTOR
	
2000-06-19  Gary Thomas  <[e-mail]>

	* include/hal_diag.h: 
	* include/plf_stub.h: 
	* src/hal_diag.c: 
	* src/sa11x0_misc.c: Update for virtual vector (debug) support.

2000-06-12  Gary Thomas  <[e-mail]>

	* src/hal_diag.c: Fix baud rates for 960,19200.  Take out "announce"
	string in ROM mode.

2000-06-05  Gary Thomas  <[e-mail]>

	* src/plf_stub.c: 
	* include/plf_stub.h: 'sa1100' shared items renamed to 'sa11x0'.

	* src/sa11x0_misc.c (hal_IRQ_handler): 
	(hal_interrupt_mask): 
	(hal_interrupt_unmask): 
	(hal_interrupt_acknowledge): 
	(hal_interrupt_configure): Complete support for GPIO interrupts.  
	Some of these are direct, others are grouped and the code needs 
	to handle both.  Also update support for GPIO edge detect interrupt 
	circuitry.

2000-06-04  Gary Thomas  <[e-mail]>

	* include/hal_cache.h: 
	* src/hal_diag.c: 
	* src/sa11x0_misc.c: Renaming of 'sa1100' shared stuff to be
	'sa11x0'.
	
	* include/hal_sa11x0.h: Renamed from 'hal_sa1100.h'.

2000-06-01  Gary Thomas  <[e-mail]>

	* src/sa11x0_misc.c: Enable caches.

	* include/hal_sa1100.h: Misc cleanups and additions necessary for
	ROM startup mode.

	* current/src/plf_stub.c:
	* current/src/hal_diag.c:
	* current/src/sa11x0_misc.c:
