* 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
