2004-09-28T17:59:53+00:00

  Allow clock setting on MPC866/MPC885 series chips according to
  environment variable `cpuclk'

* Patch by Yuli Barcohen, 20 Apr 2004:
  Remove unnecessary redefine of CPM_DATAONLY_SIZE for MPC826x

Add support for IDS "NC650" board

Patch by Yuli Barcohen, 19 Apr 2004:

2004-06-06T21:35:06+00:00

- Rename DUET_ADS to MPC885ADS
- Rename CONFIG_DUET to CONFIG_MPC885_FAMILY
- Rename CONFIG_866_et_al to CONFIG_MPC866_FAMILY
- Clean up FADS family port to use the new defines

Clean up the TQM8xx_YYMHz configurations; allow to use the same

binary image for all clock frequencies. Implement run-time
optimization of flash access timing based on the actual bus
frequency.

* Make sure to use a bus clock divider of 2 only when running TQM8xxM

2004-02-11T21:35:18+00:00

  modules at CPU clock frequencies above 66 MHz.

* Optimize flash programming speed for LWMON (by another 100% :-)

Fix variable CPU clock for MPC859/866 systems for low CPU clocks

2004-01-31T20:06:54+00:00

* Add variable CPU clock for MPC859/866 systems (so far only TQM866M):

2004-01-24T20:25:54+00:00

  see doc/README.MPC866 for details;
  implement workaround for "SIU4" and "SIU9" silicon bugs on MPC866;
  calculate CPU clock frequency from PLL register values.

* Add support for 128 MB RAM on TQM8xxL/M modules

* Cleanup lowboot code for MPC5200

2004-01-02T14:00:00+00:00

* Minor code cleanup (coding style)

* Patch by Reinhard Meyer, 30 Dec 2003:
  - cpu/mpc5xxx/fec.c: added CONFIG_PHY_ADDR, added CONFIG_PHY_TYPE,
  - added CONFIG_PHY_ADDR to include/configs/IceCube.h,
  - turned debug print of PHY registers into a function (called in two places)
  - added support for EMK MPC5200 based modules

* Fix MPC8xx PLPRCR_MFD_SHIFT typo

* Add support for TQM866M modules

* Fixes for TQM855M with 4 MB flash (Am29DL163 = _no_ mirror bit flash)

* Fix a few compiler warnings

* Patches by Xianghua Xiao, 15 Oct 2003:

2003-10-15T23:53:47+00:00

  - Added Motorola CPU 8540/8560 support (cpu/85xx)
  - Added Motorola MPC8540ADS board support (board/mpc8540ads)
  - Added Motorola MPC8560ADS board support (board/mpc8560ads)

* Minor code cleanup

* Patch by Martin Krause, 17 Jul 2003:

2003-07-17T23:16:40+00:00

  add delay to get I2C working with "imm" command and s3c24x0_i2c.c

* Patch by Richard Woodruff, 17 July 03:
  - Fixed bug in OMAP1510 baud rate divisor settings.

* Patch by Nye Liu, 16 July 2003:
  MPC860FADS fixes:
  - add MPC86xADS support (uses MPC86xADS.h)
  - add 866P/T core support (also MPC859T/MPC859DSL/MPC852T)
    o PLPRCR changes
    o BRG changes (EXTAL/XTAL restricted to 10MHz)
    o don't trust gclk() software measurement by default, depend on
      CONFIG_8xx_GCLK_FREQ
  - add DRAM SIMM not installed detection
  - use more "correct" SDRAM initialization sequence
  - allow different SDRAM sizes (8xxADS has 8M)
  - default DER is 0
  - remove unused MAMR defines from FADS860T.h (all done in fads.c)
  - rename MAMR/MBMR defines to be more consistent. Should eventually
    be merged into MxMR to better reflect the PowerQUICC datasheet.

* Patch by Yuli Barcohen, 16 Jul 2003:
  support new Motorola PQ2FADS-ZU evaluation board which replaced
  MPC8260ADS and MPC8266ADS
