[U-Boot-Users] [PATCH] I2C Dummy Driver

[Ricardo Ribalda Delgado]

Hi Wolfgang

> What is the intention or practical use of this dummy driver?


  I developed this driver for two reasons,

     I wanted a dummy driver to test the i2c subsystem
     I wanted a way of use the ddr2 autoconfiguration for ppc440 without i2c.

It is the identification data of my ddr2 memory.



I will redo this patch and sent it again if you consider it useful for
the mainline.
