Hello Wenyou,
since your patch:
commit f8b7fff1d5c5297d290acab1e398bd410b0c2e68 Author: Wenyou Yang wenyou.yang@atmel.com Date: Fri Apr 14 15:01:28 2017 +0800
serial: atmel_usart: Add clk supportsmartweb board fails booting (and I fear at last all other at91 based siemens boards also). Reverting your patch and U-Boot boots fine again.
First problem is, that I need now a bigger MALLOC_F_LEN space, but the value is for SPL and U-Boot ... but in SPL I cannot increase this value, as I have only 4k init ram.
So I need to configure a lower value in SPL as in U-Boot ... this is not possible at the moment... or?
After supporting the driver model and device tree, the size of SPL is beyond 4K. SPL is not suitable in 4K internal SRAM
Second problem: init of the uart seems to go now wrong, I have to add this patch:

May the other (none atmel) at91 based boards needs similiar fixes?
Yes, needs similar fixes.
Any hint is welcome.
