[U-Boot] Does uboot support HID-I2C

It would appear that there is a standard for running keyboards on I2C, and that Windows 8 and Linux both support it. But I could not find any references to uboot support. Is it supported or planned?

Apparently the standard has been around for about a year (I think Microsoft originally wrote it), and that now chip support is being offered to make it easy to deliver (TI just announced the TCA8424 chip).
