2003-07-18  Nick Garnett  <[e-mail]>

	* cdl/hal_arm_xscale_verde.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.
        
2003-06-21  Mark Salter  <[e-mail]>

	* src/verde_pci.c (pci_config_setup): Add dev field to PCI-X Type 0

	the bus. Thanks to [e-mail] for pointing out the need for
	this.

2002-11-12  Mark Salter  <[e-mail]>

	* include/hal_var_ints.h (CYGNUM_HAL_INTERRUPT_MSG_IBPQ): IRQ 26

	HAL_STUB_HW_WATCHPOINT_LIST_SIZE.

2002-08-12  Mark Salter  <[e-mail]>

	* cdl/hal_arm_xscale_verde.cdl: Remove CYGSEM_REDBOOT_ARM_LINUX_BOOT
	requirement.

	* cdl/hal_arm_xscale_verde.cdl: Fix linux exec address test.

	* include/hal_verde.h (CYGARC_HAL_MMU_OFF): XScale has
	special requirements for turning off MMU.

2002-05-24  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm_xscale_verde.cdl: Remove implement of
	CYGINT_HAL_VIRTUAL_VECTOR_COMM_BAUD_SUPPORT since platforms should
	define whether baud rate changes are possible.

2002-04-01  Rory Bolt  <[e-mail]>

	* include/hal_var_ints.h: Fix definition for DMA1_ERR.

2002-02-25  Mark Salter  <[e-mail]>

	* src/verde_misc.c: Timer source clock is always exactly 200MHz.

2002-02-22  Mark Salter  <[e-mail]>

	* src/verde_misc.c: Fix hw watch/break support.

2002-02-20  Mark Salter  <[e-mail]>

	* include/plf_stub.h: Add HW watchpoint/breakpoint support.
	* src/verde_misc.c: Ditto.

2002-02-19  Mark Salter  <[e-mail]>

	* src/verde_misc.c (hal_hardware_init): Initialize debug unit to
	sane state.

2002-01-31  Mark Salter  <[e-mail]>

	* src/verde_pci.c: New file. PCI support common to verde.
	* cdl/hal_arm_xscale_verde.cdl: Add verde_pci.c to compile list.
	* include/var_io.h: Move HAL_PCI_CFG_* macros from plf_io.h
	(CYGARC_PHYSICAL_ADDRESS): Fix conversion.

2002-01-30  Mark Salter  <[e-mail]>

	* src/verde_misc.c (hal_delay_us): Fix delay calculation.

2002-01-29  Jesper Skov  <[e-mail]>

	* include/var_io.h (CYGARC_PHYSICAL_ADDRESS): Added.

	* cdl/hal_arm_xscale_verde.cdl: Use common ARM linux exec
	command.
	* src/redboot_linux_exec.c: Removed.

2002-01-28  Jesper Skov  <[e-mail]>

	* cdl/hal_arm_xscale_verde.cdl: Declare var_io.h

	* include/var_io.h: Added.

	* src/verde_misc.c: Don't include CYGBLD_HAL_PLATFORM_IO_H.

	* include/hal_cache.h: Include hal_io.h

2002-01-24  Nick Garnett  <[e-mail]>

	* cdl/hal_arm_xscale_verde.cdl: Removed CYGHWR_HAL_ARM_VERDE_P_CLK
	and CYGHWR_HAL_ARM_VERDE_BUS_CLK options in favour of a more
	dynamic determination of the P_CLK value. CYGNUM_HAL_RTC_PERIOD is
	now a simple number of microseconds which is converted to the
	actual clock value in the HAL.

	* src/verde_misc.c: Rearranged clock code to make use of
	dynamically determined P_CLK value to set timer value.

2002-01-23  Mark Salter  <[e-mail]>

	* include/hal_verde.h: Add PCSR bit defines.

	* include/hal_var_ints.h (HAL_PLATFORM_RESET): Use HW feature to
	perform reset.

2002-01-23  Nick Garnett  <[e-mail]>

	* cdl/hal_arm_xscale_verde.cdl:
	Added CYGHWR_HAL_ARM_VERDE_P_CLK, which defines the external clock
	frequency applied to the Verde chip. All other CPU frequencies are
	derived from this.
	Added CYGHWR_HAL_ARM_VERDE_BUS_CLK which calculates the internal
	bus clock from the P_CLK value.
	Rewrote calculation for CYGNUM_HAL_RTC_PERIOD to derive the period
	from the bus clock and CYGNUM_HAL_RTC_DENOMINATOR.

	* src/verde_misc.c:
	Reorganized hal_IRQ_handler() to do the right thing.
	Added test to hal_interrupt_acknowledge() to acknowledge timer
	interrupts. Also removed misleading comment from hal_clock_reset().

	* include/hal_verde.h: Added TISR_WRITE().

2002-01-21  Mark Salter  <[e-mail]>

	* include/hal_verde.h: Add definitions for ATU, I2C, etc.

	* include/hal_cache.h: Turn write buffer coalescing on and off
	along with Dcache.

2002-01-18  Hugo Tyson  <[e-mail]>

	* include/hal_var_ints.h (HAL_CLOCK_REINITIALIZE): New macro
        which calls the below, also a prototype for it.

	* src/verde_misc.c (hal_clock_reinitialize): New routine to
        reset the clock to a different frequency.  This is for GPROF type
        profiling use only; not general purpose eCos usage.
	
2002-01-09  Mark Salter  <[e-mail]>

	* src/verde_misc.c: Add MCU ISR handler for ECC scrubbing.

	* include/hal_verde.h (MCU_MCISR): Define.

	* include/hal_cache.h (HAL_DCACHE_SYNC): Use platform defined
	constant instead of hardcoded flush area base.
