I also don't understand why the choice to make the union with either a DCD table or a plugin.
Confirmed with ROM team. DCD and plugin are exclusive,
You can not have both at the same time.
That's too bad, since porting from DCD-style to SPL can be useful (as Fabio has seen trying to keep some boards up-to-date).
I saw the patches. If using plugin, there is no need to use DCD.
all the things in DCD can be done in plugin code.
If we get SPL-as-plugin working, then this would form a dividing line where you need to get rid of the DCD altogether.
What about the CSF test? Your patches say that CSF and plugins are also not supported.
CSF is supported and code in nxp community. But that piece code is not included in the nxp released uboot.
Cool. Otherwise
This page is telling me that "Access is restricted".

Where is the 16k limit coming from? I don't think this is necessary, and if it is, we won't be able to load SPL using a plugin.
Confirmed with ROM team, there is no limitation. But SPL code needs to be small to be in OCRAM.
Whew! This would have killed the idea of SPL-as-plugin.
SPL is designed to run in OCRAM for i.MX6, so it's still ok to let SPL as plugin image.
Cool.
I'll take a stab at instrumenting the startup code and let you know what I find.

Eric
