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 support
smartweb 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?
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?
Any hint is welcome.
