Tested: Xilinx ZC702 eval board (single bus master 'I2C0' with multiplexer PCA9548). Write and read registers with addresses of length 0 and 1.
Note: Mainline code does not work "out of the box" on ZC702 at this time; ad hoc adaptations based on 'u-boot-xlnx' repository were needed in order to test on this board. (Those adapatations are not included with this patch.)
? Where can I find this repository?
[MRB:] At the following address. (I believe Michal Simek is the person who manages this.)
That's xilinx repo. But you should remove this from commit message. If there is something wrong in the mainline u-boot initialization in connection to this you should send patch for it. As I wrote you in other email we are going to invest our time to sync configuration from this repo with mainline in the next merge window because also these changes when they are reviewed will go to the next u-boot version.
Thanks, Michal
