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

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

2003-10-30  Gary Thomas  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: 
	* src/sa11x0_misc.c: Add support for profiling, using timer #1

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

	* cdl/hal_arm_sa11x0.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.

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

	* cdl/hal_arm_sa11x0.cdl: Removed CRUFT_H.

	* include/hal_sa11x0.h: Moved CYGARC_PHYSICAL_ADDRESS definition
	to:
	* include/var_io.h: this file.

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

	* cdl/hal_arm_sa11x0.cdl: Declare var_io.h file.
	Tug RedBoot requirements away in a component properly controlled
	by the RedBoot presence.
	* include/var_io.h: Added.

2002-01-25  Jesper Skov  <[e-mail]>

	* include/hal_sa11x0.h (CYGARC_PHYSICAL_ADDRESS): Added.

	* src/redboot_linux_exec.c: Moved to arch directory.
	* cdl/hal_arm_sa11x0.cdl: Replaced options with requirements to
	arch options.

2002-01-25  David Woodhouse  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): Trick the compiler into
	thinking that the end1 and lab1 labels are both actually used,
	so it doesn't move them around.
	
2002-01-22  David Woodhouse  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): Pass ATAG_MEM to Linux
	kernel, having tried to obtain the appropriate numbers from the
	MLT header file. This could probably do with some improvement -
	the actual information we need isn't necessarily present in the
	required form.

2002-01-14  David Woodhouse  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): Use load start/end
	parameters as defaults. Don't copy image if specified length is
	zero.

2001-10-31  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: Indicate support of variable baud rates.

2001-10-09  Hugo Tyson  <[e-mail]>

	* src/hal_diag.c (cyg_hal_plf_serial_isr): As well as the sticky
	Rx Idle bit, clear the sticky bits for interrupts for start or end
	of a line break, otherwise messing with the wiring can cause an
	interrupt loop and hang the target.

2001-08-22  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c: 
	printf() is no longer a part of RedBoot.  Thus all programs
	must use diag_printf() and related functions instead.

2001-08-21  Hugo Tyson  <[e-mail]>

	* include/hal_var_ints.h (HAL_CLOCK_LATENCY()): Define this if
	it's needed, for the routine below.

	* src/sa11x0_misc.c (hal_clock_latency): A neater fix for the
	below change: use a separate routine for measuring latency, which
	assumes it is called in the ISR, before the clock is reset.

2001-08-20  Hugo Tyson  <[e-mail]>

	* src/sa11x0_misc.c (hal_clock_read): Make hal_clock_read() return
	the true value (as expected by the kernel latency test) from the
	last interrupt if we just had that interrupt and didn't yet reset
	the clock.  Otherwise ISR latencies are reported as one tick (1cS,
	10000uS) too large.

2001-07-27  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c: Fix copyright disclaimers to satisfy
	original owner (Linux kernel maintainer Russell King).

2001-07-23  Gary Thomas  <[e-mail]>

	* src/sa11x0_misc.c (hal_IRQ_handler): Support board/platform
	specific [extended] interrupts.  On the SA11x0, these would often
	be cascaded via GPIO logic.  Use of extended macros allows SA11x0
	variant code to handle the general case, with board specific code
	defined by board packages.  Look at the iPAQ board package for
	a sample of how to use this.

2001-05-19  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): Protect compilation - scripting
	is configurable.

2001-05-17  Gary Thomas  <[e-mail]>

	* src/hal_diag.c: Allow baud rate to be settable.

2001-04-16  Gary Thomas  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: Add CDL to describe CPU family.

2001-03-23  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): 
	Entry point must be a physical address.

	* cdl/hal_arm_sa11x0.cdl: 
	Allow platforms to override default clock speed.

2001-03-20  Gary Thomas  <[e-mail]>

	* src/redboot_linux_exec.c (do_exec): Improve wait timeout.

2001-03-07  Hugo Tyson  <[e-mail]>

	* src/redboot_linux_exec.c: Do not build anything if
	HAL_PLATFORM_MACHINE_TYPE is not defined.

2001-03-02  Gary Thomas  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: HAL_PLF_INIT stuff moved to hal/common.

2001-03-01  Gary Thomas  <[e-mail]>

	* src/sa11x0_misc.c: 
	* cdl/hal_arm_sa11x0.cdl: New interface CYGINT_HAL_PLF_IF_INIT
	which, if defined, indicates that the platform has plf_if_init.

2001-03-01  Hugo Tyson  <[e-mail]>

	* src/sa11x0_misc.c: Remove warnings from lack of prototype for
	plf_if_init() - for platforms that don't have it.

2001-02-28  Gary Thomas  <[e-mail]>

	* src/sa11x0_misc.c: Allow platform to perform additional
	I/O initialization (virtual vector based).  The function
	plf_if_init() can be overridden by platform code for this.

2001-02-28  Hugo Tyson  <[e-mail]>

	* include/hal_sa11x0.h (SA11X0_TUCR_RESERVED_BITS):
	(SA11X0_TUCR_EXTERNAL_MEMORY_MASTER): Add definitions of these
	bits for enabling an external bus master.

2001-02-28  Hugo Tyson  <[e-mail]>
 
	* include/hal_sa11x0.h (SA11X0_OWER): Add OS Timer Watchdog Match
	Enable Register for use by Watchdog package.
	(SA11X0_OWER_ENABLE): And a long-winded "1" to enable it.

2001-02-24  Gary Thomas  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: Add RedBoot commands/options.
	
	* src/redboot_linux_exec.c: New file - RedBoot commands to
	support booting Linux kernel.

2001-02-23  Jesper Skov  <[e-mail]>

	* include/hal_cache.h (HAL_FLASH_CACHES_OLD_MACROS): Some
	platforms use deprecated cache handling macros.

2001-02-20  Jonathan Larmour  <[e-mail]>

	* cdl/hal_arm_sa11x0.cdl: Clarify CYGHWR_HAL_ARM_SA11X0_UART1,3
	description.

2001-02-20  Gary Thomas  <[e-mail]>

	* src/hal_diag.c: 
	* cdl/hal_arm_sa11x0.cdl: Add CDL to control which serial ports
	are available/used.

2001-02-20  Hugo Tyson  <[e-mail]>
2001-02-12  Robin Farine  <[e-mail]>

	* include/hal_sa11x0.h (SA11X0_IRQ_GPIO_9_EDGE_DETECT): Define
	this to be 9 not 0 - simple typo.  Thanks Robin!

2001-02-19  Hugo Tyson  <[e-mail]>
2001-02-12  Robin Farine  <[e-mail]>

	* src/sa11x0_misc.c (hal_clock_reset): Handles SA11X0_OSCR as a
	free running counter.
	(hal_clock_read): Adapts to changes in hal_clock_reset().
	(hal_delay_us): Likewise.

	There is only one counting register (OSCR), but multiple match
	registers and interrupt sources (OSMR1-OSMR3).  Setting our match
	register to COUNT and the counter register to 0 each tick makes it
