	* include/hal_intr.h (CYGARC_REG_SYSTICK_CSR_CLK_SOURCE): Define
	this value so that it may be overridden by the variant or platform
	HAL. Default to external clock source if it is not defined.

	* src/hal_misc.c (hal_reset_vsr): Allow VSR table to be positioned
	anywhere in memory, as specified by the value of hal_vsr_table.

2009-06-29  Nick Garnett  <nickg@ecoscentric.com>

	* include/hal_arch.h (HAL_HWDEBUG_BREAKPOINT): 
	* src/context.S (_gdb_hwdebug_breakpoint): 
	* cdl/hal_cortexm.cdl: Add support for GDB fileio debugging.

2009-04-02  Nick Garnett  <nickg@ecoscentric.com>

	* include/hal_intr.h (CYGNUM_HAL_EXCEPTION_MIN)
	(CYGNUM_HAL_EXCEPTION_MAX): Fix these definitions.
	(HAL_DISABLE_INTERRUPTS): Add "&" constraint to output register to
	prevent compiler allocating same register as input.

2009-03-13  Nick Garnett  <nickg@ecoscentric.com>

	* src/hal_misc.c (hal_reset_vsr): Add additional startup type
	ROMINT, to equate to ROM application using internal, rather than
	external, RAM. For some targets, ROM already means this; a
	different option should probably be used to control the semantics
	here.

2009-02-27  Simon Kallweit  <simon.kallweit@intefo.ch>

	* include/hal_io.h: Added system control register definitions 

2009-02-26  Nick Garnett  <nickg@ecoscentric.com>

	* src/cortexm.ld: Add C++ exception support (not contributed to
	anoncvs).

2009-02-13  Nick Garnett  <nickg@ecoscentric.com>

	* include/hal_arch.h: Add include for var_arch.h.
	(HAL_IDLE_THREAD_ACTION): Tidy up debug code left in by mistake.

	* src/hal_misc.c:
	* src/cortexm.ld: 
	Modified SRAM linker section to support initialisation from ROM.

2008-12-03  Nick Garnett  <nickg@ecoscentric.com>

	* src/hal_misc.c (hal_deliver_interrupt): Fix instrumentation call
	to allow it to compile properly.

2008-11-24  Simon Kallweit  <simon.kallweit@intefo.ch>

	* include/hal_io.c: Fixed MASK_ macro.

2008-11-05  Nick Garnett  <nickg@ecoscentric.com>

	* src/context.S (mcount): Add implementation of this function to
	support profiling.

	* src/vectors.S (hal_default_interrupt_vsr): Add
	CYGPKG_PROFILE_GPROF to conditions for saving the interrupt state.

2008-11-04  Simon Kallweit  <simon.kallweit@intefo.ch>

	* include/hal_intr.h:
	Fixed load value of SysTick counter.
	* src/hal_misc.c:
	Fixed wrap-around in hal_delay_us().

2008-11-04  Simon Kallweit  <simon.kallweit@intefo.ch>

	* include/hal_intr.h:
	Fixed base address in reset function.

2008-10-28  Nick Garnett  <nickg@ecoscentric.com>

	* include/hal_io.h: Add definitions for NVIC SHCSR register.

	* src/hal_misc.c (hal_reset_vsr): Enable Usage, Bus and Mem fault
	handlers in SHCSR register.

	* src/hal_misc.c (hal_deliver_interrupt): Add support for chained
	interrupts.
	(hal_interrupt_end): Only increment scheduler lock when the kernel
	is present.

	* include/hal_arch.h (HAL_THREAD_INIT_CONTEXT): Add end-stop to
	new thread states to terminate GDB backtraces.

2008-10-07  Nick Garnett  <nickg@ecoscentric.com>

	* cdl/hal_cortexm.cdl: Add implements for
	CYGINT_LIBSTDCXX_NO_CXX_EXCEPTION_REG_FRAME_IMPL to disable C++
	tests.
