Hi Jagan,

many thanks - with your help i got it work :-)
I tried both, mainline u-boot and which one from openedev.

I observed a little issue on both versions.
If i type "reset" or press the SRST_B button i get:

U-Boot SPL 2015.07-rc3-g0cf5d8d (Sep 18 2015 - 11:22:16)
mmc boot
zynq_sdhci_init: sdhci_host malloc fail
MMC Device 0 not found
spl: mmc device not found
### ERROR ### Please RESET the board ###


if i simple power on or press the POR_B button it works as expected:

U-Boot SPL 2015.07-rc3-g0cf5d8d (Sep 18 2015 - 11:22:16)
mmc boot
reading system.dtb
spl_load_image_fat_os: error reading image system.dtb, err - -1
