2007-01-25  Andrew Lunn  <[e-mail]>

	* include/var_io.h (AT91_PITC_VALUE_MASK): New - mask to access
	the PITC value which is a 20 bit number.

2006-05-17  Andrew Lunn  <[e-mail]>

2006-03-10  Oliver Munz  <[e-mail]>

	* src/timer_pit.c: fix hal_delay_us(). hal_clock_read for
	initializing the PIT if needed. Change hal_clock_reset() to allow
	setting of a new period.  This is required when the timer is
	started by hal_delay_us() or hal_clock_read() before
	hal_clock_initialize().

2006-03-23  Andrew Lunn  <[e-mail]>

	* src/timer_pit.c (hal_delay_us): Start the PIT if it is not
	running when hal_delay_us is called. This happens when the kernel
	is not used. Problem found by Oliver Munz.

2006-03-10  Oliver Munz  <[e-mail]>

	* src/hal_diag.c (cyg_hal_plf_serial_isr): Change the #ifdefs to

2006-02-19  Andrew Lunn  <[e-mail]>
           Oliver Munz  <[e-mail]>

	* cdl/hal_arm_at9a.cdl: Add the AT91SAM7S variant and control
 	  for new timer and debug usart code.
	* include/var_io.h: Register definitions for AT91SAM7S

	  for any platform specific initialization
	* src/at91_misc.c (hal_at91_reset_cpu): Use the reset controller 
	  if it exists.
	* src/at91_misc.c (hal_IRQ_handler): Decode interrupts from
	  the system controller if it exists.
	* src/timer_tc.c (NEW) eCos timer using the Timer Counter
	* src/timer_pit.c (NEW) eCos timer using Periodic Interval Timer
	* src/hal_diag_dbg.c (NEW) Debug output via debug UART.
	* src/hal_diag.h: Indicate hal_at91_reset_cpu() is a C function
	  otherwise we have problems with the watchdog driver which is C++.

2005-05-30  Ezequiel Conde <[e-mail]>

	* src/at91_misc.c ( hal_delay_us ): Clear status before running
	delay
	
2004-11-12  Jani Monoses <[e-mail]>

	* include/var_io.h: Added defines for some missing UART bits,
	corrected a few timer capture mode register bits.

2004-11-12  Andrew Lunn  <[e-mail]>

	* src/hal_diag.c: Only support the third serial port if we have
	the defines needed. Not all HAL do have.

2004-11-11  Sebastian Block <[e-mail]>

	* src/hal_diag.c: Added support for the third serial port
	
2004-10-06  Andrea Michelotti <[e-mail]>

	* include/var_io.h: protected PDC/SPI DMA registers from redefinition.
	The HAL may of already defined them.
	
2004-10-05  Savin Zlobec <[e-mail]>

	* include/var_io.h: Added definitions for AT91M55800A SPI and PIO
	pins.

2004-09-17  Andrea Michelotti <[e-mail]>

	* cdl/hal_arm_at91.cdl: 
	* src/at91_misc.c:
	* include/var_io.h:
	* include/var_arch.h: added jtst target
	
2004-09-16  Andrea Michelotti <[e-mail]>

	* cdl/hal_arm_at91.cdl:
	* src/at91_misc.c:
	* include/var_io.h: Support FIQ as a high priority interrupt using 
	the normal mechanism. This is controlled by the CDL option 
	CYGHWR_HAL_ARM_AT91_FIQ and uses the interrupt number 
	CYGHWR_HAL_ARM_AT91_FIQ which is common to all platforms using
	this HAL variant. 
		
2004-08-30  Thomas Koeller <[e-mail]>

	* cdl/hal_arm_at91.cdl: Reversed change of 2004-02-12 that move
	seemingly 'common' options from the platform to the variant. This
	was breaking some platform HALs.

2004-08-12  Jani Monoses <[e-mail]>

	* src/at91_misc.c: Mask all interrupts before calling 
	hal_if_init() not after, so if it creates interrupts
	they do not get disabled.

2004-05-24  Gratian Crisan <[e-mail]>

	* include/var_io.h: Added waveform mode definitions for 
	timer/counter.

2004-02-19  Daniel N閞i  <[e-mail]>
 
        * cdl/hal_arm_at91.cdl (CYGBLD_GLOBAL_CFLAGS): Honour CYGHWR_THUMB
        and CYGBLD_ARM_ENABLE_THUMB_INTERWORK.
	* cdl/hal_arm_at91.cdl (CYGBLD_GLOBAL_LDFLAGS): Ditto.
 
2004-02-18  Daniel N閞i  <[e-mail]>

	* cdl/hal_arm_at91.cdl: Define CYGNUM_HAL_ARM_AT91_CLOCK_SPEED with
	a default_value so it can be overridden in the platform HAL.
	* src/hal_diag.c (cyg_hal_plf_serial_control): Properly terminate
	variable argument processing.
	* include/hal_diag.h: prototype for hal_at91_set_leds() to avoid
	compiler warning.
	
2004-02-12  Jani Monoses <[e-mail]>

	* cdl/hal_arm_at91.cdl: Put configuration options common to all
	variants here. Replace
	CYGNUM_HAL_VIRTUAL_VECTOR_CHANNELS_DEFAULT_BAUD with the two
	separate options for console and debug channels as used by most
	HALs.
	* src/hal_diag.c: Implement
	CYGINT_HAL_VIRTUAL_VECTOR_COMM_BAUD_SUPPORT so baudrate is
	changeable from RedBoot.
	
2003-12-05  Andrew Lunn  <[e-mail]>

	* include/hal_diag.h: hal_delay_us() is a C function.

2003-12-02  Thomas Koeller  <[e-mail]>

	* include/var_io.h: Improved accuracy for baud rate divider
	computation.

2003-10-23  Thomas Koeller  <[e-mail]>

	interrupts.
	
2003-08-21  Thomas Koeller  <[e-mail]>

        * include/var_io.h:
        Fixed minor typo.
	
2003-08-20  Daniel N閞i  <[e-mail]>

	* include/var_io.h: Fix typos (duplicates) from last change.

2003-08-18  Thomas Koeller  <[e-mail]>

        * include/var_io.h:
        Added bitmask definitions for PIO.
	
2003-08-06  Daniel N閞i  <[e-mail]>

	* src/at91_misc.c (hal_clock_reset):
	Don't acknowledge interrupt here (this is handled
