Targets with CONFIG_NEEDS_MANUAL_RELOC do not use REL/RELA relocation (mostly only GOT) where functions aray are not updated. This patch is fixing function pointers for DM core and serial-uclass to ensure that relocated functions are called.

How long will we have to carry this patch? It seems that if we add any new driver we will have to add more code like this?
This patch is unfortunate. Can we discontinue CONFIG_NEEDS_MANUAL_RELOC some day?
This patch (or similar one) has to be alive when we have platform which requires CONFIG_NEEDS_MANUAL_RELOC for full u-boot. There is an option to move to REL/RELA but the question is if all platforms have it/support it. Unfortunately I think that it will be in the tree for a long time.
If we use SPL, we do not have to relocate code, I think.
SPL doesn't have relocation that's why this code is not used there.
Maybe I asked this before, but when can we remove CONFIG_NEEDS_MANUAL_RELOC? What platforms need it?
