[PATCH 00/18] prepare for porting OP-TEE communication support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Ahmad Fatoum (18):
  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
  include: implement dev_warn_once and friends
  include: add blocking notifier aliases
  include: add Linux ktime API
  of: define of_devices_ensure_probed_by_compatible
  include: add linux/device.h wrapper around driver.h
