2002-08-29  Mark Salter  <msalter@redhat.com>

        * include/plf_stub.h: Add HAL_STUB_HW_BREAKPOINT_LIST_SIZE and
        HAL_STUB_HW_WATCHPOINT_LIST_SIZE.

2002-05-07  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_frv_frv400.cdl: 
        Make CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT more standard.

2001-12-10  Richard Sandiford  <rsandifo@redhat.com>

        * src/frv400_misc.c (hal_interrupt_mask): Disable LAN interrupts
        in the FPGA's register.
        (hal_interrupt_unmask): Re-enable them.

2001-12-10  Richard Sandiford  <rsandifo@redhat.com>

        * src/frv400_misc.c (hal_clock_reset): Shift high word of timer left.
        (hal_clock_read): Likewise.
        (hal_delay_us): Increase timeout.  Correct off-by-one error when
        time is a multiple of _MIN_DELAY us.

2001-12-10  Richard Sandiford  <rsandifo@redhat.com>    

        * include/plf_stub.h (HAL_FRV_ENTER_DEBUG_MODE): Remove NOPs.
        Mark LR as clobbered due to changes in vectors.S:_break.
        (HAL_FRV_EXIT_DEBUG_MODE): Remove NOPs.  Don't modify PSR or BPSR.
        * src/frv400_misc.c (get_bpsr, set_bpsr): New.
        (break_handler): Rework.  Set up BPSR to reflect the current
        privelege level and trap state before exiting from debug mode.
        Re-enter debugging mode and restore the old BPSR before returning.
        (cyg_hal_plf_hw_breakpoint): Remove unnecessary DDR diddling.
        (cyg_hal_plf_hw_watchpoint): Likewise.

2001-11-28  Hugo Tyson  <hmt@redhat.com>

        * include/plf_stub.h (HAL_FRV_ENTER_DEBUG_MODE): New macro; simple
        performs a "break" to enter debug mode (with cooperation from
        RedBoot/stubs/traphandler).
        (HAL_FRV_EXIT_DEBUG_MODE): New macro; jumps through hoops to
        return to normal mode from debug mode.  Can only be used from
        debug mode, or the CPU halts.  The hoops are on fire.
        (HAL_STUB_HW_BREAKPOINT):
        (HAL_STUB_HW_WATCHPOINT):
        (HAL_STUB_IS_STOPPED_BY_HARDWARE): Defines APIs so that stubs can
        set hardware debug support, and tell whether we stopped for a
        hardware debug reason.

        * src/frv400_misc.c (break_handler): Special handler for break
        instruction and all debug traps, to enable below.
        (cyg_hal_plf_hw_breakpoint): 
        (cyg_hal_plf_hw_watchpoint): 
        (cyg_hal_plf_is_stopped_by_hardware): New routines to manipulate
        hardware debug resources.

        * include/frv400.h (_BRR_SB): Some new symbols for debug regs.

2001-10-23  Gary Thomas  <gthomas@redhat.com>

        * src/frv400_misc.c: Try to avoid [re]init PCI bus.

        * include/frv400.h: Moved common register layouts to 'arch'.

2001-10-20  Gary Thomas  <gthomas@redhat.com>

        * src/frv400_misc.c (hal_delay_us): Handle small delays properly.

2001-10-19  Julian Smart <julians@redhat.com>

        * Added CYPKG_MEMALLOC to redboot_ROMRAM.ecm so the release script
        knows about it.

2001-10-16  Gary Thomas  <gthomas@redhat.com>

        * src/frv400_misc.c (_frv400_pci_translate_interrupt): 
        Handle interrupts from PCI slots.

        * include/plf_ints.h (HAL_PLATFORM_RESET): Remove unused variable.

2001-10-15  Gary Thomas  <gthomas@redhat.com>

        * include/platform.inc: Getting on-board SRAM to function.  Of course,
        the hardware doesn't match the documentation...

2001-10-12  Gary Thomas  <gthomas@redhat.com>

        * src/frv400_misc.c (hal_interrupt_acknowledge): Fix support for
        onboard (LAN) interrupts.

        * include/plf_ints.h: Define PCI based interrupts.

        * src/frv400_misc.c (hal_hardware_init): 
        * include/frv400.h: Add support for onboard FPGA (local interrupts).

2001-10-11  Gary Thomas  <gthomas@redhat.com>

        * src/frv400_misc.c: Clean up PCI code.

        * misc/redboot_ROMRAM.ecm: Add BSP syscalls.
