        define whether baud rate changes are possible.

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

2002-01-29  Jesper Skov  <jskov@redhat.com>

        * 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  <jskov@redhat.com>

        * 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  <nickg@redhat.com>

        * 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  <msalter@redhat.com>

        * 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  <nickg@redhat.com>

        * 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  <msalter@redhat.com>

        * 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  <hmt@redhat.com>

        * 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  <msalter@redhat.com>

        * 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.
