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
