I'm currently upgrading our u-boot-xlnx code base for our custom board from 2013.7 to 2015.1.I have an issue where the last lines of FSBL output and first few lines of u-boot output are corrupted on hand over from the FSBL as show below.

The 2015.1 u-boot successfully boots linux with no further corruption.
If I download the 2015.1 u-boot to ram using XMD and ps7_init.tcl then the corruption does not occur.
I have cut the CONFIG_SYS_BAUDRATE_TABLE to just have 115200 to no avail.
Any suggestions on how to proceed gratefully received.
