Layerscape Gen2 SoC supports GPIO registers to control GPIO signals. Adding support of GPIO structure to access GPIO registers.t rebase --continue
Signed-off-by: Pratiyush Srivastava pratiyush.srivastava@nxp.com Signed-off-by: Prabhakar Kushwaha prabhakar.kushwaha@nxp.com --- Changes for v2: Incorporated York's comments - Removed CONFIG_SYS_GPIO1_ADDR as bool - Renamed CONFIG_SYS_GPIO1_ADDR
This structure is required while supporting ethernent in LS1012AFRDM.
