The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>
