I would like to plan how we can introduce the architecture in U-Boot. First at all, I beg you to split the huge series into small pieces. It is quite difficult to review. I suggest you extract parts that are not related to MX8. Some of patches in the series can be already be merged because unrelated. For example, I2C patches: lpi2c: Fix bus stop problem in xfer lpi2c: Add bus busy error handling They can be simply merged because they fix issues. Some other Ye's patch fall into this category and can be merged independently foro mi.MX8. I will also ask to split Patch 1 in small and easier to review pieces.
