Master bank:
Except System Clock bank, any bank in a given column of banks which are only within the vicinity can be selected as Master bank
A Master bank will always have VRN/VRP pins unused. Due to this in a given bank VRN/VRP pins will be reserved if it is selected as Master bank
All the Data group banks in the given column acts as Slave banks if a Master bank is selected in that column. The same is given in the generated UCF file 。
A master bank must be selected for each column if DCI cascade is to be used.
If VRN/VRP pins are utilized for pin allocation in a bank, the DCI cascading
feature must be applied to support DCI. In this case, a master bank must be
selected.
不知道为什么ml605的选了bank25,bank26不行吗?

bank25是不是那一列bank的中间bank?7系列DDR控制器选择的bank必须在同一列，地址控制bank必须是中间bank，估计你选用的器件有类似的要求，可以查看下MIG手册。
