u-boot/include/configs/MPC86xADS.h
wdenk 2535d60277 * Patch by Martin Krause, 17 Jul 2003: 
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
