Speaking of the code fragment below (from lib_ppc/board.c), I would like to send a patch so that bi_iic_fast is initialized from "i2cfast" environment variable (if defined). This parameter is passed to Linux to set the i2c driver mode.

Of course, this variable should be in the environment when system is booting and any change should be saved to environment first and board should be reset to take effect. There are other environment variables in the same file that behave this way. This is only going to be used when CONFIG_405GP and CONFIG_405EP is defined.

What do you think?

%%% begin fragment %%%

#if defined(CONFIG_405GP) || defined(CONFIG_405EP) bd->bi_pci_busfreq = get_PCI_freq ();

#ifdef CFG_OPB_FREQ bd->bi_opbfreq = CFG_OPB_FREQ; #else bd->bi_opbfreq = 50000000; #endif bd->bi_iic_fast[0] = 0; bd->bi_iic_fast[1] = 0; #endif #endif

%%% end fragment %%%
