This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

Convert rman to use rman_res_t instead of u_long

2016-01-27T02:23:54Z

Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

Use IIC_EBUSBSY and IIC_BUSERR status values consistantly across all drivers.

2015-10-09T22:49:50Z

Make it clearer what each one means in the comments that define them. IIC_BUSBSY was used in many places to mean two different things, either "someone else has reserved the bus so you have to wait until they're done" or "the signal level on the bus was not in the state I expected before/after issuing some command". Now IIC_BUSERR is used consistantly to refer to protocol/signaling errors, and IIC_BUSBSY refers to ownership/reservation of the bus.

Make ofw_bus_get_node() consistently return -1 when there is no associated

OF node, instead of a random mixture of 0 and -1. Update all checks for 0 to check for -1 instead. MFC after: 4 weeks
