2007-04-12ppc4xx: Fix i2c divisor calcularion for PPC4xxJeffrey Mann
This patch fixes changes the i2c_init(...) function to use the function get_OPB_freq() rather than calculating the OPB speed by sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is specific per processor. The prior method was not and so was calculating the wrong speed for some PPC4xx processors.

2007-02-20[PATCH] PPC4xx: Add support for multiple I2C bussesStefan Roese
This patch adds support for multiple I2C busses on the PPC4xx platforms. Define CONFIG_I2C_MULTI_BUS in the board config file to make use of this feature. It also merges the 405 and 440 i2c header files into one common file 4xx_i2c.h. Also the 4xx i2c reset procedure is reworked since I experienced some problems with the first access on the 440SPe Katmai board. Signed-off-by: Stefan Roese <sr@denx.de>
