Sorry, I don't understand anything here. At which exact place is there any such 4 k alignment restriction? When we relocate U-Boot, we just process a list of addresses. Even if the start of the image is aligned to a 4 k boundary, there are a zillion of other addresses that are not, and these can be relocated just fine. So why exactly would there be such a restriction on the start address of the image? Note especially, that the start address of the image is just where the text segment starts - it is not necessarily the entry point address where code execution begines.
