2003-02-13  Patrick Doyle  <wpd@delcomsys.com>
        * src/nano_misc.c: Replaced explicit prototype of memset with
        #include <string.h>.

2002-08-12  Mark Salter  <msalter@redhat.com>

        * misc/redboot_POST.ecm: Remove CYGSEM_REDBOOT_ARM_LINUX_BOOT.
        * misc/redboot_RAM.ecm: Ditto.

2002-05-14  Jesper Skov  <jskov@redhat.com>

        * src/nano_misc.c: Fixed warning.

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

        * cdl/hal_arm_sa11x0_nano.cdl: 
        Standardize CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT usage.

2002-03-06  Jesper Skov  <jskov@redhat.com>

        * misc/redboot_RAM.ecm: Updated. Added zlib.
        * misc/redboot_ROM.ecm: Same.

2002-01-30  Jonathan Larmour  <jlarmour@redhat.com>

        * include/nano.h (HAL_PCI_DO_CONFIG_ACCESS): If requesting vendor
        config, check it isn't 0 or 256 which would be bogus - instead
        this indicates the device is absent, e.g. the second eth controller
        that is found on the commEngine, but not on the nanoEngine.

2002-01-28  Jesper Skov  <jskov@redhat.com>

        * include/plf_io.h: Added.

        * cdl/hal_arm_sa11x0_nano.cdl: Remove explicit plf_io.h
        declaration.

2001-05-02  Hugo Tyson  <hmt@redhat.com>

        * src/nano_misc.c (hal_mmu_init): Set up PCI memory in the new
        location, where it will not already be mapped by the default
        layout.  This requires "stealing" RAM from the linear layout.
        It's done this way so that a RAM app will work OK atop an
        old-style RedBoot with the old PCI window area set up.
        (hal_arm_mem_real_region_top): Better comments, and a safety
        check; do not repeat the test for boundary movement.
        
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.ldi: 
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.h: 
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.mlt: 
        * include/pkgconf/mlt_arm_sa11x0_nano_post.ldi: 
        * include/pkgconf/mlt_arm_sa11x0_nano_post.h: 
        * include/pkgconf/mlt_arm_sa11x0_nano_post.mlt: 
        Add "fixed" region to contain PCI window at 0xfa00000 (250Mb),
        well away from normal memory.  Adjust ram region size to 15Mb - a
        smaller possible memory installation, with the 1Mb default PCI
        window removed.

2001-04-27  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal_arm_sa11x0_nano.cdl: Remove redundant -Wl,-N from link flags

2001-04-12  Hugo Tyson  <hmt@redhat.com>

        * src/nano_misc.c (hal_arm_mem_real_region_top): Also report
        variants on the CYGMEM_SECTION_heap1 as described by default.
        This is ugly, but necessary, else the heap tries to use memory
        that is not installed.  Oh, for a proper MLT!

2001-04-02  Hugo Tyson  <hmt@redhat.com>

        * misc/readme.txt: Update the readme to reflect more info about
        using the nano target.

2001-03-29  Hugo Tyson  <hmt@redhat.com>

        * src/nano_misc.c (hal_mmu_init): Find the real physical address
        for mapping the uncacheable, unbufferable PCI window - it might be
        various places depending on what SDRAMs are installed.

2001-03-14  Hugo Tyson  <hmt@redhat.com>

        * include/nano.h (HAL_PCI_INIT): Disconnect the two ethernet
        devices from the PCI bus during init so that we can re-scan during
        startup regardless of what happened before - such as
        network-enabled RedBoot doing the same setup already.

        * misc/redboot_POST.ecm: 
        * misc/redboot_RAM.ecm: 
        Enable package CYGPKG_IO_ETH_DRIVERS so that RedBoot is network
        capable.  Disable CYGPKG_DEVS_ETH_ARM_NANO_ETH1 so that it uses
        only the first ether device.  Tidy some comments and whitespace.

2001-03-08  Jesper Skov  <jskov@redhat.com>

        * cdl/hal_arm_sa11x0_nano.cdl:  Removed
        CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED which is now the
        default.

2001-03-01  Hugo Tyson  <hmt@redhat.com>

        * include/pkgconf/mlt_arm_sa11x0_nano_post.h:
        * include/pkgconf/mlt_arm_sa11x0_nano_post.ldi: 
        * include/pkgconf/mlt_arm_sa11x0_nano_post.mlt:
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.h:
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.ldi:
        * include/pkgconf/mlt_arm_sa11x0_nano_ram.mlt:
        Add MLT definition of PCI window.
        I chose 0x1e00000 ie. megabyte 30 because I believe
        megabyte 31 is used by RedBoot for buffers or stacks.
        
        * include/nano.h: Take external MLT definition of PCI window for
        defining BASE, SIZE symbols.  Set the interrupts on GPIO0 and
        GPIO1 to be falling-edge in HAL_PCI_INIT().  Don't define any of
        this unless CYGPKG_IO_PCI and not assembler.

        * src/nano_misc.c (hal_mmu_init): Take external MLT definition of
        PCI window.  Also define and initialize an int holding the real
        address of the PCI window, if CYGPKG_IO_PCI.

2001-02-28  Hugo Tyson  <hmt@redhat.com>

        * include/plf_mmap.h (HAL_VIRT_TO_PHYS_ADDRESS): [et al] Use
        variant HAL routines which scan the true memory map installed.
        This is necessary for dealing with eg. PCI window - also future
        similar targets with different physical memory arrangements,

        * src/nano_misc.c (plf_hardware_init): Perform MMU initialization
        even in RAM startup - so that different configurations of
        ROM(RedBoot) and RAM app can work together.
        (hal_mmu_init): Perform partial initialization when in RAM startup
        - so that ROM settings can be overridden eg. for PCI non-cacheable
        memory windows and the like.  [Incomplete initial version.]

        * include/nano.h (HAL_PCI_INIT): Implement this and all its mates,
        ie. a PCI device driver for the nanoBridge and *very specifically*
        its two attached i82559s only - it's by no means general, because
        it's not a proper implementation of a PCI bridge.

2001-02-22  Hugo Tyson  <hmt@redhat.com>

        * misc/redboot_POSTecm: 
        * misc/redboot_RAM.ecm: add configuration of the Flash Image
        System initialization in RedBoot.

2001-02-20  Hugo Tyson  <hmt@redhat.com>

        * cdl/hal_arm_sa11x0_nano.cdl: New CDL describing serial
        ports - CYGHWR_HAL_ARM_SA11X0_UART1,3.

        * cdl/hal_arm_sa11x0_nano.cdl: Also changed the default baud rates
        to 38400, having realized that the other port works just fine too.
        So you can put your serial line on the non-BSE port for normal
        work and not be hassled by out-of-time characters over reset.

2001-02-15  Hugo Tyson  <hmt@redhat.com>

        * misc/redboot_POST.ecm: 
        * misc/redboot_RAM.ecm:
        Add CYGPKG_IO_FLASH for RedBoot builds now that flash driver
        exists.   CYGPKG_DEVS_FLASH_NANO + CYGPKG_DEVS_FLASH_STRATA

2001-02-14  Hugo Tyson  <hmt@redhat.com>

        * include/hal_platform_setup.h: Clean up debug and cache hacks to
        get it limping along.  Import proper value (as read from system
        regs) to SDRAM controller setup - in case true ROM startup is ever
        used.

        * src/nano_misc.c (hal_arm_mem_real_region_top): Add.  Support
        hal_dram_size.
        (hal_mmu_init): Add a SDRAM sizer like others we have.  Just in
        case.  Deals with 32Mb sized parts also.

        * cdl/hal_arm_sa11x0_nano.cdl: implements
        CYGINT_HAL_ARM_MEM_REAL_REGION_TOP

2001-02-14  Hugo Tyson  <hmt@redhat.com>

        * hal/arm/sa11x0/nano: New package, based on Assabet 
        HAL.  This is the nanoEngine from Bright Star Engineering; an
        SA1110 CPU + 2x i82559 ethernets.
