[U-Boot] Zynq board is boken

[Masahiro Yamada]

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

    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.
