Subversion Repositories openrisc

2003-04-10  Nick Garnett  

        * src/sh.ld:

        Added entry for .stack section in data section.

2003-01-31  Mark Salter  

        * src/hal_syscall.c (hal_syscall_handler): Let generic syscall code

        handle exit.

2002-08-02  Andrew Lunn 

        * cdl/hal_sh.cdl: The Redboot exec command can now be

          disabled by CDL

2002-04-30  Jesper Skov  

        * include/hal_var_sp.inc: Allow variant to provide custom

        interrupt vector layout. This means the size of

        hal_interrupt_handlers/objects/data can be reduced if the vector

        layout is sparse. Something similar could be done for

        _HW_EXEC_ENTRY_TABLE, saving exception_vector_int entries in the

        $vectors_code block. However, this code usually resides in flash

        so there's not much point given todays flash block sizes.

        * cdl/hal_sh.cdl: Added CYGHWR_HAL_SH_FPU and

        CYGHWR_HAL_SH_NO_FPU, allowing an arch level control of FPU

        related tests.

        Skipping test handled in a different way now, so the implements

        statement has been deleted again.

2002-04-29  Jesper Skov  

        * include/hal_var_bank.inc: Define hal_exception_entry_extras and

        hal_interrupt_entry_extras.

        * include/hal_var_sp.inc: Define hal_exception_entry_extras and

        hal_interrupt_entry_extras. Disable interrupts on exception

        entry.

        * src/vectors.S: Call hal_exception_entry_extras and

        hal_interrupt_entry_extras.

2002-04-29  Jonathan Larmour  

        * src/vectors.S:

        Don't use .file as it can confuse debugging since the .file

        doesn't contain the path and therefore the debugger will never

        know where it lives! This conflicts with using -Wa,--gstabs.

2002-04-15  Jonathan Larmour  

        * src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to

        __do_syscall.

2002-04-22  Jesper Skov  

        * include/hal_var_sp.inc: 7044 needs different vector layout than

        76xx since its vectors are hardwired.

2002-04-18  Jesper Skov  

        * include/hal_var_sp.inc: Do no translation of entry address if

        cache module defines CYGARC_SH_MOD_CAC_NO_WINDOWS.

        * include/hal_intr_vecs.h: Move all vectors after IRQ7 to variant

        header. Define _IRQ and _LVL for all of the first 7

        interrupts. Define CYGNUM_HAL_INTERRUPT_LVL_MAX

2002-03-06  Jesper Skov  

        * include/hal_var_sp.inc: Fix asm comments.

2002-02-28  Jesper Skov  

        * src/hal_syscall.c (hal_syscall_handler): Added.

        * src/sh_stub.c (__is_bsp_syscall): Added.

        * cdl/hal_sh.cdl: Build hal_syscall.c

2002-02-27  Jesper Skov  

        * src/sh_stub.c (__computeSignal): Changed to use DATA_ACCESS

        names as well.

        * include/hal_intr_vecs.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,

        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Same.

        * include/hal_intr_vecs.h: Use DATA_ACCESS vector names instead of

        ADDRESS_ERROR names.

2002-02-15  Jesper Skov  

        * src/sh_stub.c (__single_step): Use normal breakpoint instruction

        (trapa #32) for single-stepping.

        On the SH2 the use of trapa#255 causes a different (and unhandled)

        exception, in the range reserved for application

        exceptions/interrupts.

2002-02-14  Jesper Skov  

        * include/hal_var_bank.h: Switch mach/macl entries.

        * include/hal_var_sp.inc: Reserve (additional) trampoline for NMI

        to make eCos interrupt numbers match. Make traps use trap numbers

        32-64.

        (hal_cpu_save_regs): Remember to adjust SP for R0 save location.

        (hal_cpu_restore_regs_return): Rewritten to fix errors and allow

        SP to be changed from GDB.

2002-02-13  Jesper Skov  

        * src/context.S (hal_thread_load_context): Load up stack pointer

        before enabling interrupts.

        * include/hal_var_sp.inc: Fetch the VSR pointer and jump to it

        instead of into the VSR table.

        (hal_cpu_restore_regs_return): adjust sp to point to exception

        state before returning.

        * include/hal_var_bank.inc: Include SH3 register references. Make

        better use of some delay slots.

        * src/vectors.S: Don't save exception/interrupt state on stack

        with debug markers. Load up event value in R4 before calling

        hal_intc_decode so it can be a nop if desired. Removed some SH3

        register references.

        * include/hal_var_sp.inc: Include SH2 offsets, export

        _HW_EXC_ENTRY_TABLE, fix some typos.

        * include/hal_intr_vecs.h: IRL vectors renamed. Added IRQ

        vectors.

2002-01-16  Jesper Skov  

        * include/hal_var_bank.h: Fix typo.

        * src/sh_stub.c (__computeSignal): Only handle defined vectors.

        * include/hal_intr_vecs.h: Decode NMI as interrupt 0, moved all

        other vectors. Provide MEM_FAULT vector range.

        * include/hal_var_sp.inc: Changes for NMI-as-interrupt-0.

        * include/hal_var_sp.h: Renamed vector to event to share code.

        * include/hal_intr_excevt.h: Added MEM_FAULT vector ranges and

        CYGHWR_SH_RTC_TIMER_IS_TMU.

        * src/hal_misc.c (hal_delay_us): Only build if

        CYGHWR_SH_RTC_TIMER_IS_TMU. Use MEM_FAULT vector range.

        * include/hal_intr.h: Deleted clock controls.

        * cdl/hal_sh.cdl: Use CYGNUM_HAL_RTC_PRESCALE instread of

        module-specific prescale variable.

        * include/hal_intr_excevt.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,

        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Define.

        * include/hal_intr_vecs.h: Same.

        * src/hal_misc.c (cyg_hal_exception_handler): Use new _MEM_FAULT

        vector range.

        * include/hal_intr_vecs.h: Removed RTC code.

        * include/hal_arch.h: Changed breakpoint instruction to match that

        used in GDB 5.1.

        It also makes better sense on the SH2.

        * include/hal_intr_excevt.h: Interrupt/exception vectors and clock

        handling code moved here...

        * include/hal_intr.h: From here.

        * include/hal_intr_vecs.h: Interrupt/exception vector layout +

        clock handling for SH1/SH2 variants.

        * include/hal_var_sp.inc: Added some comments, fixed number of

        pre-VSR vectors, renamed HW_VSR_TABLE to HW_EXC_ENTRY_TABLE to

        avoid confusion (it has nothing to do with eCos VSRs). Finally,

        made the pre-VSR stuff only compile when really required (since

        it's 4KiB).

2002-01-14  Jesper Skov  

        * include/hal_arch.h: Moved HAL_SavedRegisters structure to

        bank variant headers. Same with HAL_THREAD_INIT_CONTEXT,

        for SH3/SH4 variants.

        * include/hal_var_bank.h: Added. Contains old hal_arch.h stuff for

        SH3/SH4 variants.

        * src/hal_mk_defs.c: Added conversion for entry stack.

2001-11-16  Nick Garnett  

        * src/hal_misc.c (hal_msbit_index): Fixed this function so that it

        actually works!

        * cdl/hal_sh.cdl: improved the description on the RTC constants

        component.

2001-10-11  Jesper Skov

        CYGINT_HAL_SH_PLF_LITTLEENDIAN_DEFAULT CDL interface.

        * src/sh.ld: Support .rel.got input sections.

2001-09-05  Jesper Skov

2001-08-22  Gary Thomas  

        * src/redboot_linux_exec.c:

        printf() is no longer a part of RedBoot.  Thus all programs

        must use diag_printf() and related functions instead.

2001-07-09  Jesper Skov  

        * src/sh_stub.c: Fixed potential SH4 problem in UBC handling.

2001-07-02  Jesper Skov

2001-06-19  Jesper Skov  

        * src/redboot_linux_exec.c: Only base address, entry and cmdline

        options are always used. Other commands only affect image if

        set. This allows combined kernel&initrd images to be loaded in one

        file where the initrd address & size is already recorded at the

        start of the image.

2000-11-24  Jonathan Larmour  

        * src/sh.ld: _reset should be adorned with CYG_LABEL_DEFN

        * src/vectors.S: CYG_LABEL_DEFN should have been used everywhere

        that CYG_LABEL_NAME was used, except for the scheduler lock which

        is special as it is defined in C as an asm alias.

        * include/arch.inc: Similarly here for symbol macros

        * include/basetype.h (CYG_LABEL_NAME): Delete. This is now obsolete.

        a macro which calculates the proper values based on baud rate

        and CPU clock speed.

        * include/sh_regs.h:

        Adding new module definitions, conditionally included depending on

        counter for switches to interrupt_stack.

        * src/context.S: Save and restore interrupt state on thread

        switches.

        * include/hal_arch.h: Set thread initial SR state to allow
