2006-01-27 Will Wagner 

        * include/ppc8xx.h: Add definition for frame and parity errors in BD ctrl.

        Changed macro calculating SMCMR CLEN.

2004-04-01  Robert Chenault  

        * include/ppc8xx.h: Add definition for 8 bytes to spi_pram structure

        (for a total of 48 bytes) as is done in the i2c_pram structure. Then

        remove the equivalent 8 reserved bytes in the scc_pram structure.

2003-09-08  Gary Thomas  

        * src/quicc_smc1.c: Fix baud rate clock setup - was off by 1.

        Reported by Tord Andersson 

2003-03-31  Gary Thomas  

        * src/quicc_smc1.c (cyg_hal_sccx_init_channel): Proper handling

        (signal routing) for SCC3 - differs on 850 and 850T!

2003-03-31  Jonathan Larmour  

        * src/quicc_smc1.c (cyg_hal_smcx_init_channel):

        (cyg_hal_sccx_init_channel):

        * src/cpm.c: Include  for memset().

        (_mpc8xx_reset_cpm): use CPM busy flag to check reset completion.

        * src/quicc_smc1.c: Include  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.

2003-03-23  Gary Thomas  

        * src/quicc_smc1.c: Use new baud rate generator allocation functions.

        Merge SMC and SCC output functions.

        * src/cpm.c: Add new function to allocate and manage the baud rate

        generators.  Used by all serial drivers.

        * include/ppc8xx.h: Some common definitions moved here from various

        QUICC serial files.

        * cdl/hal_powerpc_quicc.cdl: Add interface for SCC4 (not implemented

        by any platform yet)

2003-03-20  Gary Thomas  

        * src/cpm.c (_mpc8xx_allocBd): Improve "best guess" for intial DPRAM

        allocation to use a value which is likely not to conflict with old

        versions of RedBoot.

2003-03-18  Gary Thomas  

        * src/quicc_smc1.c (cyg_hal_sccx_init_channel): Update initialization

        for SCC2 - *CAUTION* not tested on actual hardware.

2003-03-06  Gary Thomas  

        * src/cpm.c: Handle case where DPRAM allocation is unknown.

        * include/ppc8xx.h: Define limits of CPM/DPRAM space.

2003-03-05  Gary Thomas  

        * 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  

        * 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  

        * 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  

        * 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  

        * 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  

        * 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  

        * src/quicc_smc1.c: Fix warning.

2001-09-10  Jonathan Larmour  

        * cdl/hal_powerpc_quicc.cdl (CYGNUM_HAL_QUICC_DIAG_BAUD):

        234000->230400 typo.

2001-07-31  Jonathan Larmour  

2001-07-31  Christoph Csebits  

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

        reserve space.

2001-01-26  Jesper Skov  

        * src/quicc_smc1.c: Removed CYGSEM_HAL_VIRTUAL_VECTOR_DIAG check.

2001-01-15  Gary Thomas  

        * 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  

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

2000-08-30  Jesper Skov  

        * src/quicc_smc1.c (cyg_hal_plf_serial_init_channel): Move all

        init code to init_channel.

2000-06-30  Jesper Skov  

        * src/quicc_smc1.c: calling i/f macro changes.

2000-06-28  Jesper Skov  

        * include/quicc_smc1.h:

        * src/quicc_smc1.c: Cleanup.

2000-06-26  Jesper Skov  

        * include/quicc_smc1.h:

        * src/quicc_smc1.c: Added non-block/timout features. Reworked

        Ctrl-c support code.

2000-06-22  Jesper Skov  

        * src/quicc_smc1.c: Fix compiler warning. Add functions to deal

        with ctrl-c interrupts from the device.

2000-06-21  Jesper Skov  

        * 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  

        * src/quicc_smc1.c (hal_ctrlc_isr): Check that interrupt is

        generated by serial controller.

2000-06-13  Jesper Skov  

        * src/quicc_smc1.c:

        * include/quicc_smc1.h:

        Added ctrlc handling for use via virtual vector table.

2000-03-03  Gary Thomas  

        * src/quicc_smc1.c: Use common CPM defines (now in ppc8xx.h).

        * include/ppc8xx.h: Add some generic defines for CPM.  Also

        refine ucode area for easier use (someday).

start-serialize-newcdl

2000-02-29  Gary Thomas  

        * 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  

        * 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  

        * src/quicc_smc1.c (cyg_quicc_smc1_uart_rcvchar): Get frequency

        from new CYGHWR_HAL_POWERPC_BOARD_SPEED variable.

2000-02-03  Jesper Skov  

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

1999-09-02  Gary Thomas  

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

1999-09-01  Gary Thomas  

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

1999-06-27  Gary Thomas  

        * 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  

        * 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  

        * 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  

        * src/quicc_smc1.c (init_smc1_uart): Use default 38400 Baud,

        because it is better.

1999-06-18  Jesper Skov  

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

1999-06-17  Hugo Tyson  

        * src/quicc_smc1.c (init_smc1_uart): Initialize the baud rate

        depending on the system clock setting.

1999-06-15  Hugo Tyson  

        * 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  

        * 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  

        * 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

        New files.
