Hi Simon,
I am playing with driver model and I have moved uartlite to it and it is working fine for normal u-boot +10k but SPL size is dramatically bigger. Without DM I can fit to 3k but now it has ~16k.

This 9k is after removing all printf calling which is adding 6kB.

I took a look at this quite recently and your numbers (4KB) are similar to mine - for ARM. I suppose. Actually on Tegra I see 5KB but I think that is due to GPIOs being used too. I expect Thumb will cut this by 20% or so.
There is also a bug in gcc which causes the rodata to blow up. You might be seeing that also.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303
I just got a response with a possible patch on the gcc mailing list.
So this is very much work-in-progress. I see a few options:
1. Reduce functionality further, like the existing CONFIG_DM_WARN/DEVICE_REMOVE/STDIO but operating on things like device_bind/probe(). I have not seriously looked at this but I suspect it would be painful.
2. Support for static binding, i.e. declare a struct udevice directly, using const static init and perhaps some sort of macro to help thread tings together. Then we could add CONFIG_DM_BIND (to support binding new devices) and disable it for SPL. A bit ick but it might get us closer to running in a 4KB SRAM.
If you have ideas/patches please send them through. Right now I need to get Kconfig support v2 landed, and we still need a few more gdata patches before we can enable DM in SPL anyway (Tom is looking at that).
Regards, Simon
