        * cdl/hal_arm_sa11x0.cdl: CYGPRI_KERNEL_TESTS_DHRYSTONE_PASSES added.

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

        * 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  <jskov@redhat.com>

        * 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  <jskov@redhat.com>

        * 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  <dwmw2@cambridge.redhat.com>

        * 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  <dwmw2@cambridge.redhat.com>

        * 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  <dwmw2@cambridge.redhat.com>

        * 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  <jlarmour@redhat.com>

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

2001-10-09  Hugo Tyson  <hmt@redhat.com>

        * 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  <gthomas@redhat.com>

        * 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  <hmt@redhat.com>

        * 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  <hmt@redhat.com>

        * 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  <gthomas@redhat.com>

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

2001-07-23  Gary Thomas  <gthomas@redhat.com>

        * 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  <gthomas@redhat.com>

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

2001-05-17  Gary Thomas  <gthomas@redhat.com>

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

2001-04-16  Gary Thomas  <gthomas@redhat.com>

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

2001-03-23  Gary Thomas  <gthomas@redhat.com>

        * 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  <gthomas@redhat.com>

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

2001-03-07  Hugo Tyson  <hmt@redhat.com>

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

2001-03-02  Gary Thomas  <gthomas@redhat.com>

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

2001-03-01  Gary Thomas  <gthomas@redhat.com>

        * 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  <hmt@redhat.com>

        * 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  <gthomas@redhat.com>

        * 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  <hmt@redhat.com>

        * 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  <hmt@redhat.com>
 
        * 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  <gthomas@redhat.com>

        * 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  <jskov@redhat.com>

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

2001-02-20  Jonathan Larmour  <jlarmour@redhat.com>

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

2001-02-20  Gary Thomas  <gthomas@redhat.com>

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

2001-02-20  Hugo Tyson  <hmt@redhat.com>
2001-02-12  Robin Farine  <acnrf@dial.eunet.ch>

        * 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  <hmt@redhat.com>
2001-02-12  Robin Farine  <acnrf@dial.eunet.ch>

        * 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
        very hard to use the other match registers - whereas they are
        intended for easy general use.

        This change sets our match register OSMR0 to the next time
        interval and leaves the OSCR freerunning so that other match
        registers can easily be used, which is much more flexible, and
        much more what was intented.

        Because the OSCR is just a counter, and the match registers
        compare only for exact equality, no special measures to deal with
        the counter wrapping/overflowing are needed.

2001-02-08  Jesper Skov  <jskov@redhat.com>

        * src/hal_diag.c: Replace CYGSEM_HAL_DIAG_MANGLER_None with
        CYGDBG_HAL_DIAG_TO_DEBUG_CHAN.

2001-02-01  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_ints.h: Include registers definitions used in
        reset macro.

2001-01-31  Jesper Skov  <jskov@redhat.com>

        * src/hal_diag.c: Replaced CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL

        * include/hal_mm.h: Change bitfields within memmap entry to
        unsigned, so that we can compare values successfully - otherwise
        "0x02" sign-extends and is never equal after promotion!

        * include/hal_cache.h: Include the platform memory map
        interrogation definitions from <cyg/hal/plf_mmap.h> and header for
        the new functions below.

        * src/sa11x0_misc.c (hal_virt_to_phys_address): 
        (hal_phys_to_virt_address):

        real memory map in force to verify the static translations defined
        in the efficient macro versions.

        * tests/mmap_test.c (endif): New file: testcase for memory map
        interrogation macros and verification functions.

        * cdl/hal_arm_sa11x0.cdl: Build the testcase.

2000-12-13  Hugo Tyson  <hmt@redhat.com>

        * cdl/hal_arm_sa11x0.cdl: Define a symbol CYGBLD_HAL_VAR_INTS_H so
        that the architectural HAL can see <cyg/hal/hal_var_ints.h> below.

        * include/hal_var_ints.h: New file; actually a copy of all the
        platforms' hal_platform_ints.h for all the sa11x0 platforms.

        * include/hal_mm.h: New file; actually an excerpt from all the
        platforms' $PLATFORM_misc.h for all the sa11x0 platforms, which
        describes MM table layout and macros for initializing it.

2000-12-12  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_arm_sa11x0.cdl: Allow RTC clock rate to be changable.

2000-12-04  Hugo Tyson  <hmt@redhat.com>

        * include/hal_cache.h: Consistently ensure that ARM registers used
        in MCR ops to cache-control coprocessors, where the data doesn't
        matter, all actually have data zero ("SBZ") as in the Jaggar book.
        This may well not be necessary, but for the sake of making sure...

2000-12-01  Hugo Tyson  <hmt@redhat.com>

        * include/hal_cache.h: Define addressable cache line operations
        HAL_DCACHE_STORE(), HAL_DCACHE_INVALIDATE(), HAL_DCACHE_FLUSH()
        now that I have understood how come the test (kcache2) was
        failing.  See kernel ChangeLog for details.  Also tidied up a
        couple of other minor details.

2000-11-27  Gary Thomas  <gthomas@redhat.com>

        * src/hal_diag.c (init_channel): UART setup required on Brutus as well.

2000-11-21  Gary Thomas  <gthomas@redhat.com>

        * src/hal_diag.c (init_channel): Disable broken uart setups on platforms
        other than the SA1110MM, since this code seems to be somewhat broken.

        * src/sa11x0_misc.c (hal_clock_reset): Add code to compensate for
        clock drift since this hardware does not reset on interrupts.
        (hal_clock_read): Also adjust the value returned here for same reason.

2000-06-22  Gary Thomas  <gthomas@redhat.com>

        * src/hal_diag.c (hal_diag_write_char): 
        Fix typo: CYGINT_HAL_GDB_PORT_VECTOR to be CYGHWR_HAL_GDB_PORT_VECTOR

        (hal_interrupt_unmask): 
        (hal_interrupt_acknowledge): 
        (hal_interrupt_configure): Complete support for GPIO interrupts.  
        Some of these are direct, others are grouped and the code needs
