2004-04-22  Jani Monoses <[e-mail]>

	 * cdl/hal_frv_frv400.cdl :
	 Invoke tail with stricter syntax that works in latest coreutils. 

2003-12-05  Andrew Lunn  <[e-mail]>

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

2003-09-21  Gary Thomas  <[e-mail]>

	* misc/redboot_RAM.ecm: 
	* misc/redboot_ROMRAM.ecm:  Adjust for changes in RedBoot
	template - DNS now must be enabled manually.

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

	* cdl/hal_frv_frv400.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.
        
2002-08-29  Mark Salter  <[e-mail]>

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

2002-05-07  Gary Thomas  <[e-mail]>

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

2001-12-10  Richard Sandiford  <[e-mail]>

        * 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  <[e-mail]>

	* 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  <[e-mail]>	

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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  <[e-mail]>

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

2001-10-19  Julian Smart <[e-mail]>

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

2001-10-16  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

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

2001-10-12  Gary Thomas  <[e-mail]>

	* 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  <[e-mail]>

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

	* misc/redboot_ROMRAM.ecm: Add BSP syscalls.
