ARM: zynq: disable CONFIG_SYS_MALLOC_F to fix MMC boot
Since commit 326a682358c1 (malloc_f: enable SYS_MALLOC_F by default
if DM is on), Zynq MMC boot hangs up after printing the following:
U-Boot SPL 2015.04-rc5-00053-gadcc570 (Apr 08 2015 - 12:59:11)
mmc boot
reading system.dtb
Prior to commit 326a682358c1, Zynq boards enabled CONFIG_DM, but
not CONFIG_SYS_MALLOC_F. That commit forcibly turned on
CONFIG_SYS_MALLOC_F. I have not figured out the root cause, but
anyway it looks like CONFIG_SYS_MALLOC_F gave a bad impact on the
Zynq MMC boot.
We are planning to have the v2015.04 release in a few days.
I know this is a defensive fixup, but what I can do now is to add
# CONFIG_SYS_MALLOC_F is not set
to every Zynq defconfig file to get back the original behavior.
Tested on:
- Zedboard
- ZC706 board
