The usage of the common.h include file is deprecated [1], and has already been removed from several files.

2023-12-19tee: optee: don't enumerate services if there ain't anyEtienne Carriere
Change optee driver service enumeration to not enumerate (and allocate a zero sized shared memory buffer) when OP-TEE reports that there is no service to enumerate. This change fixes an existing issue that occurs when the such zero sized shared memory buffer allocated from malloc() has a physical address of offset 0 of a physical 4kB page. In such case, OP-TEE secure world refuses to register the zero-sized shared memory area and makes U-Boot optee service enumeration to fail.

2023-01-11optee: bind the TA drivers on OP-TEE nodePatrick Delaunay
In U-Boot driver model the devices can be referenced by phandle in the U-Boot configuration nodes. Without a valid node provided during the bind, the driver associated to OP-TEE TA can't be referenced. For example to force the sequence number with alias (.flags = DM_UC_FLAG_SEQ_ALIAS) aliases { rng0 = &optee; }; or other configuration: board-sysinfo { compatible = "vendor,sysinfo-board"; ramdom = <&optee>; } With this patch all drivers bound from OP-TEE service discovery are now associated are associated to OP-TEE node, allowing to identify by phandle the driver provided by the TA for one UCLASS without modifying device tree.

This change defines resources for OP-TEE service drivers to register themselves for being bound to when OP-TEE firmware reports the related service is supported. OP-TEE services are discovered during optee driver probe sequence which mandates optee driver is always probe once bound. Discovery of optee services and binding to related U-Boot drivers is embedded upon configuration switch CONFIG_OPTEE_SERVICE_DISCOVERY.

Right now the error messages when optee has a version mismatch or shared memory is not configured are done with a debug(). That's not very convenient since you have to enable debugging to figure out what's going on, although this is an actual error. So let's switch the debug() -> dev_err() and report those explicitly.

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-12-05drivers: optee: rpmb: fix returning CID to TEEJorge Ramirez-Ortiz
The mmc CID value is one of the input parameters used to provision the RPMB key. The trusted execution environment expects this value to be specified in big endian format. Before this fix, on little endian systems, the value returned by the linux kernel mmc driver differed from the one returned by u-boot. This meant that if linux provisioned the RPMB key, u-boot would not have access to the partition (and the other way around).
