u-boot-xlnx xilinx-v2015.4 does not seem to support subpage nand writes

Hi All,

 

I am working with a custom Zynq 7Z020 board and noticed in the latest tagged version of u-boot that sub-pages writes were not working.  I tracked this down to nand_base.c:nand_write_subpage_hwecc() calling chip->ecc.hwctl which is not implemented in zynq_nand.c

 

Does anyone have any experience with this?   I am not sure if I have something misconfigured or if this may be a bug in the Xilinx nand driver.

 

Thanks,

Sam
