2003-12-05  Andrew Lunn  <andrew.lunn@ascom.ch>

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

2003-12-02  Thomas Koeller  <thomas.koeller@baslerweb.com>

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

2003-10-23  Thomas Koeller  <thomas.koeller@baslerweb.com>

	* src/at91_misc.c: Fixed recognition of spurious
	interrupts.
	
2003-08-21  Thomas Koeller  <thomas.koeller@baslerweb.com>

        * include/var_io.h:
        Fixed minor typo.
	
2003-08-20  Daniel Néri  <daniel.neri@sigicom.se>

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

2003-08-18  Thomas Koeller  <thomas.koeller@baslerweb.com>

        * include/var_io.h:
        Added bitmask definitions for PIO.
	
2003-08-06  Daniel Néri  <daniel.neri@sigicom.se>

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

2003-07-18  Nick Garnett  <nickg@balti.calivar.com>

	* cdl/hal_arm_at91.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.
        
2003-06-25  Daniel Néri  <daniel.neri@sigicom.se>

	* src/at91_misc.c (hal_interrupt_set_level): Fix assert condition;
	AT91 interrupt priority levels are between 0 and 7.

2003-06-24  Jonathan Larmour  <jifl@eCosCentric.com>

	* include/var_io.h: Remove not seemingly useful AT91_PMC_SCER_CPU.

	* cdl/hal_arm_at91.cdl: We have a var_arch.h so define
	CYGBLD_HAL_ARM_VAR_ARCH_H.

	* include/var_arch.h: New file containing
	overrides for hal_arch.h.
	(HAL_IDLE_THREAD_ACTION): override here by defining power saving modes
	for idle actions.

2003-06-04  Daniel Néri  <daniel.neri@sigicom.se>

	* src/at91_misc.c (hal_hardware_init): Make sure the AIC internal
	priority level stack is flushed.
	(hal_IRQ_handler): Calculate active interrupt by dummy read from
	the IVR, which has the side-effect of updating ISR with the
	current interrupt source number.
	(hal_interrupt_acknowledge): Write to ICCR is not needed, as
	interrupt deassertion is taken care of by read of IVR in
	hal_IRQ_handler.

2003-05-27  Daniel Néri  <daniel.neri@sigicom.se>

	* include/var_io.h: Add missing USART register defines.
	Fix cut'n'paste typos in AT91_PS defines.

	CPU clock disable command bit.

2003-05-15  Thomas Koeller  <thomas.koeller@baslerweb.com>

	* include/hal_diag.h:
	* src/at91_misc.c: Added function to generate a hardware reset
	using the watchdog.
	
2003-05-15  Nick Garnett  <nickg@balti.calivar.com>

	* src/at91_misc.c (hal_delay_us): Added calculation to better
	approximate the number of timer ticks for a given number of
	microseconds. This code also now adjust to the actual CPU clock
	speed on different platforms.

2003-05-12  Nick Garnett  <nickg@balti.calivar.com>

	* src/at91_misc.c: Change definition of hal_IRQ_handler() to be
	variant-indepenendent, and to use HAL_LSBIT_INDEX() rather than an
	explicit scan of the ipr bits. Tidied up file a little to make
	more readable.

	* include/var_io.h: Reorganized to allow platform HALs to define
	base addresses of on-chip devices if they differ from the defaults
	defined here. Added variant definitions of Power Management
	devices for different parts.

	* cdl/hal_arm_at91.cdl:	Calculate CYGNUM_HAL_RTC_PERIOD from
	CYGNUM_HAL_ARM_AT91_CLOCK_SPEED, which is defined by the platform.
	Added CYGHWR_HAL_ARM_AT91 to define the specific Atmel AT91 part
	being supported. This must be defined by the platform HAL.
	Added define_proc to generate CYGBLD_HAL_ARM_VAR_IO_H.

	* src/hal_diag.c (hal_diag_led): Now calls hal_at91_set_leds().

2002-07-14  Tim Drury <tdrury@siliconmotorsports.com>

	* cdl/hal_arm_at91.cdl: moved clock speed parameter to platform specific cdl
	* include/var_io.h: added PIO_PDSR register
	* src/hal_diag.c: added hal_diag_led()

2002-05-08  Gary Thomas  <gthomas@redhat.com>

	* misc/redboot_ROMRAM.ecm:
	* misc/redboot_ROM.ecm: Disable 'fconfig' since the FLASH is too small.

2001-08-17  George Hampton <george.hampton@intel.com>
2001-08-17  Gary Thomas  <gthomas@redhat.com>

	* include/hal_platform_ints.h (CYGNUM_HAL_ISR_COUNT): PR 22864
	Don't adjust by "min" value if not doing translations.
	
2001-07-26  Gary Thomas  <gthomas@redhat.com>

	* src/at91_misc.c (hal_clock_initialize): 
	* cdl/hal_arm_at91.cdl: Increase system clock (RTC) to run at 1MHz for
	better timing resolution.  CAUTION! this means that the system clock tick
	can never be more than 64ms.

2001-07-23  Gary Thomas  <gthomas@redhat.com>

	* src/hal_diag.c (cyg_hal_plf_serial_control): Enable ^C support.

	* src/at91_misc.c (hal_clock_initialize): Add clock/rtc implementation.

	* include/pkgconf/mlt_arm_at91_eb40_romram.ldi: 
	Replace missing 'fixed vectors'.

	* include/pkgconf/mlt_arm_at91_eb40_ram.ldi: 
	* include/hal_platform_setup.h: Fix ROMRAM startup mode.  Note: I
	can't get the onboard SRAM at 0x00100000 to work, so for now, this
	will just have to go in low external RAM.  Thus the change for the
	RAM base address in startup=RAM mode.

	* src/hal_diag.c (cyg_hal_plf_serial_getc_timeout): Remove debug code.

	* src/at91_misc.c (set_leds): LEDs are on D4/D2/D1.

	* include/pkgconf/mlt_arm_at91_eb40_ram.ldi: 
	* include/pkgconf/mlt_arm_at91_eb40_ram.h:

	* include/plf_io.h: Add definitions for PIO, EBI and PS.

	* include/hal_platform_setup.h: ROM startup mode now works.
	First attempt at ROMRAM startup - not yet working.
