[PATCH v2 00/20] prepare for porting OP-TEE communication support

So far, barebox support for OP-TEE was restricted to loading it either
early in PBL or via bootm and to not step over it when allocating
memory. This was guarded behind CONFIG_HAVE_OPTEE.

To prepare porting the Linux driver behind CONFIG_OPTEE, which
brings actual bidirectional communication with OP-TEE to barebox,
let's import some of the headers and APIs used by the v6.6 Linux
driver.

v1 -> v2:
See individual change log in every patch.

Ahmad Fatoum (20):
include: provide linux/errno.h
include: add linux/refcount.h
bitops: split off linux/bits.h
include: import <linux/instruction_pointer.h>
asm-generic: split off typeconfused readl and friends
asm-generic: migrate relaxed helpers into asm-generic/io.h
include: add linux/io.h with strict prototypes
include: import Linux word-at-a-time.h
string: implement strscpy
of: add CONFIG_OF for Linux compatibility
include: asm-generic/atomic.h: define atomic_cmpxchg
kbuild: build barebox for -std=gnu11
include: linux/idr.h: implement more Linux API
test: self: add simple IDR test
include: implement dev_warn_once and friends
include: add blocking notifier aliases
include: add Linux ktime API
of: constify string pointed to by struct of_device_id::compatible
of: define of_devices_ensure_probed_by_compatible
include: add linux/device.h wrapper around driver.h
