Hello Wenyou,
since your patch:
commit f8b7fff1d5c5297d290acab1e398bd410b0c2e68

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.
