Define a platform data structure for the MPC85XX GPIO driver to allow use of the driver without device tree. Users should define the GPIO blocks for their platform like this: struct mpc85xx_gpio_plat gpio_blocks[] = { { .addr = 0x130000, .ngpios = 32, }, { .addr = 0x131000, .ngpios = 32, }, };
U_BOOT_DEVICES(my_platform_gpios) = { { "gpio_mpc85xx", &gpio_blocks[0] }, { "gpio_mpc85xx", &gpio_blocks[1] }, };
This is intended to build upon the recent submission of the base MPC85XX driver from Mario Six. We need to use that new driver without dts support and this patch gives us that flexibility. This has been tested on a Freescale T2080 CPU, although only the first GPIO block.

Applied to u-boot-dm/next, thanks!
