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
Hmm... no?
I have running a SPL (without DM/DTS support of course) from current mainline source on the board. Only problem is, that we need different MALLOC_F_LEN space in SPL and U-Boot now!
added Simon Glass and Tom Rini, may I oversee some obvious config and/or they have an idea?
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.
:-(
So your patch broke all none atmel at91 boards?
Just trying on the at91 based corvus board, same problem, but the same fixes did not yet help ... need more debug time here ... The taurus board is currently down, after fixing the smartweb and corvus boards, I hope to get it running again, but I think, same problem.
BTW: This is again a good example how important it is to use automated tests, may with tbot [1] I only detected this, because I have running automated weekly U-Boot mainline tests. I think we have a lot of (not only at91) dead/untested boards in code ...
