[U-Boot] at91: smartweb board fails with current HEAD

[Heiko Schocher <hs@denx.de>]

Hello Wenyou,

since your patch:

commit f8b7fff1d5c5297d290acab1e398bd410b0c2e68
Author: Wenyou Yang <wenyou.yang@atmel.com>

     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.
