OMAP54xEVM and GPMC

I'm working towards getting the GPMC (16-bit non-multiplexed) working on the OMAP54xEVM with a custom FPGA, and I noticed that the most significant address bit is not available on the board.  From the user guides, the gpmc_a25 pin is shared with gpio3_79, which is used for Ethernet reset on the EVM board.

I'm planning to move forward, and I'll assume the address range is limited to 1024 bytes per chip select (MSB is always 0), but I wanted to make sure that this would not cause any additional issues with GPMC operations.


Thanks!
