* Add support for multiple I2C busesBen Warren2006-11-03-5/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, Attached is a patch providing support for multiple I2C buses at the command level. The second part of the patch includes an implementation for the MPC834x CPU and MPC8349EMDS board. /*** Note: This patch replaces ticket DNX#2006083042000018 ***/ Signed-off-by: Ben Warren <bwarren@qstreams.com> Overview: 1. Include new 'i2c' command (based on USB implementation) using CONFIG_I2C_CMD_TREE. 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that the commands to change bus number and speed are only available under the new 'i2c' command mentioned in the first bullet. 3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form of an array of bus-device pairs. Otherwise, it is an array of uchar. CHANGELOG: Added new 'i2c' master command for all I2C interaction. This is conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for setting I2C bus speed as well as changing the active bus if the board has more than one (conditionally compiled with CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses. Updated README. regards, Ben

| | | | | | | | | - show PCI clock frequency on MPC8260 systems - add FCC_PSMR_RMII flag for HiP7 processors - in do_jffs2_fsload(), take load address from load_addr if not set explicit, update load_addr otherwise - replaced printf by putc/puts when no formatting is needed (smaller code size, faster execution)

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
