        * src/quicc_smc1.c (cyg_hal_smcx_init_channel): 
        (cyg_hal_sccx_init_channel): 

        * src/cpm.c: Include <string.h> for memset().
        (_mpc8xx_reset_cpm): use CPM busy flag to check reset completion.
        * src/quicc_smc1.c: Include <string.h> for memset().
        (cyg_hal_smcx_init_channel): Don't reset CPM here - let variant
        initialization do it. Only let through RX interrupts.
        (cyg_hal_sccx_init_channel): Ditto.

2003-03-06  Gary Thomas  <gary@mlbassoc.com>

        * src/cpm.c: Handle case where DPRAM allocation is unknown.
        
        * include/ppc8xx.h: Define limits of CPM/DPRAM space.

2003-03-05  Gary Thomas  <gary@mlbassoc.com>

        * src/quicc_smc1.c: Need to flush data cache because the serial
        driver may set use buffers in cacheable memory.  Without this,
        diag_printf() falls over if the serial driver is ever used.

        * src/cpm.c: New file with CPM/DPRAM support.

        * include/ppc8xx.h: 
        * cdl/hal_powerpc_quicc.cdl: Split out support for CPM/DPRAM.

2002-11-26  Gary Thomas  <gthomas@ecoscentric.com>

        * src/quicc_smc1.c: Initialize BD allocation point.  Note that it is
        different from when the CPM get's reset directly.  This is to allow
        sharing of the space between ROM (RedBoot) code and applications.

        * cdl/hal_powerpc_quicc.cdl: Move platform define here, where it belongs.

2002-11-25  Gary Thomas  <gthomas@ecoscentric.com>

        * src/quicc_smc1.c: Support any combination of SMC1/SMC2 and
        SCC1/SCC2/SCC3 [or at least lay foundation for it]

        * cdl/hal_powerpc_quicc.cdl: Add more controls over port layout.

2002-07-18  Gary Thomas  <gary@chez-thomas.org>

        * src/quicc_smc1.c (cyg_hal_scc1_init_channel): Fix init which
        failed from power-up - wrong channel in CP command!

2002-07-11  Gary Thomas  <gary@chez-thomas.org>

        * src/quicc_smc1.c: 
        * include/quicc_smc1.h: 
        * cdl/hal_powerpc_quicc.cdl: Add support for SCC1 as a serial
        console (for newer chips which have this available).

2002-06-25  Gary Thomas  <gary@chez-thomas.org>

        * src/quicc_smc1.c: 
        * cdl/hal_powerpc_quicc.cdl: Use more common CDL name for baudrate
        CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_BAUD.

2002-05-30  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c: Fix warning.

2001-09-10  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal_powerpc_quicc.cdl (CYGNUM_HAL_QUICC_DIAG_BAUD):
        234000->230400 typo.

2001-07-31  Christoph Csebits  <christoph.csebits@frequentis.com>

        * include/ppc8xx.h: 4 SCCs are supported by MPC860T, so don't
        reserve space.

2001-01-26  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c: Removed CYGSEM_HAL_VIRTUAL_VECTOR_DIAG check. 

2001-01-15  Gary Thomas  <gthomas@redhat.com>

        * src/quicc_smc1.c: Provide for multiple serial input buffers
        since the single buffer/descriptor model fails miserably on some
        newer chips [at least 855T].

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

        * include/ppc8xx.h: Layout of I2C and IDMA was [slightly] wrong.

2000-08-30  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c (cyg_hal_plf_serial_init_channel): Move all
        init code to init_channel.

        Ctrl-c support code.

2000-06-22  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c: Fix compiler warning. Add functions to deal
        with ctrl-c interrupts from the device.

2000-06-21  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c: 
        * include/quicc_smc1.h: 
        Allow callers to specify base. Added code to initialize vector
        procs table.

2000-06-16  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c (hal_ctrlc_isr): Check that interrupt is
        generated by serial controller.

        * src/quicc_smc1.c:

        refine ucode area for easier use (someday).

start-serialize-newcdl
2000-02-29  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/quicc_smc1.c (UART_BAUD_RATE): Use CDL option for baud rate.

        * cdl/hal_powerpc_quicc.cdl: Add option to control diag serial
        baud rate, rather than being fixed at 38400.

end-serialize-newcdl
2000-02-21  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/quicc_smc1.c (UART_BIT_RATE): Handle system clock speeds
        which are not integer multiples of MHz, e.g. 33.33 MHz.

2000-02-04  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c (cyg_quicc_smc1_uart_rcvchar): Get frequency
        from new CYGHWR_HAL_POWERPC_BOARD_SPEED variable.

2000-02-03  Jesper Skov  <jskov@redhat.com>

        * src/quicc_smc1.c: CYG_HAL_POWERPC_x->CYGPKG_...

1999-09-02  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/quicc_smc1.c (init_smc1_uart): Generalize baud rate computation.

1999-09-01  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/ppc8xx.h: Add some missing definitions (MAR, MBMR).

1999-06-27  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/quicc_smc1.c: Many changes which allow these routines to
        cooperate when the SMC is being used by a serial "driver" as well.
        In particular, remove "hard coded" resources on the SMC.
        Note: there is some lingering problem with the transmit routines
        [globally] after the serial driver re-inits the SMC.  Of course
        this problem is intermittent, so it's hard to fix.

1999-06-24  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c (cyg_hal_gdb_isr): Add this routine to trap ^C
        events and stop the system, if CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT.

1999-06-24  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c (cyg_quicc_init_smc1): Remove unused, commented
        out code, that was left over from CygMon version of this file.

1999-06-18  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c (init_smc1_uart): Use default 38400 Baud,
        because it is better.

1999-06-18  Jesper Skov  <jskov@cygnus.co.uk>

        * include/pkgconf/hal_quicc.h: Fixed CDL description.

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c (init_smc1_uart): Initialize the baud rate
        depending on the system clock setting.

1999-06-15  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c: Moved include of ppc8xx.h

        * src/ppc8xx.h: Removed, to...

        * include/ppc8xx.h: New file.  Moved here so that platform startup
        code can share it.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/quicc_smc1.c: Make this file safe for compilation even when
        no PowerPC 860 is in use; pkgconf can enable this component for
        any target, potentially.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * ChangeLog: Component created, based partly on the FADS work and
        on CygMon's serial IO code for the MBX860, to support the Motorola
        MBX860 QUICC serial controller for basic IO.
        Initially only used in the neighbouring platform component
        HAL_POWERPC_MBX [hal/powerpc/mbx/....] 

        * include/quicc_smc1.h
        * include/pkgconf/hal_quicc.h
        * src/PKGconf.mak
        * src/ppc8xx.h
        * src/quicc_smc1.c
