[U-Boot] Zynq board is boken

Hi Michal, (cc Simon)

Bad new.

My Zedboard would not boot from MMC card with the U-Boot mainline.

U-Boot hangs after printing "reading system.dtb". I think, other zynq board types, too.

I did git-bisect and the first bad commit is:

commit 326a682358c16afcf2c7a9617e9811e72a1f0929 Author: Masahiro Yamada yamada.masahiro@socionext.com Date: Thu Mar 19 19:42:55 2015 +0900

malloc_f: enable SYS_MALLOC_F by default if DM is on

Uh, sorry. My commit.

The commit 36a6823 enables CONFIG_SYS_MALLOC_F=y CONFIG_SYS_MALLOC_F_LEN=0x400 to the .config file.

I suspect it changed how Zynq initializes malloc area in SPL. I have not figured out how to fix it.

Any hint is appreciated.
