tee: optee: discover services dependent on tee-supplicant

2022-12-23T08:26:15+00:00

Makes OP-TEE to enumerate also services depending on tee-supplicant
support in U-Boot. This change allows OP-TEE services like fTPM TA
to be discovered and get a TPM device registered in U-Boot.

tee: optee: don't fail probe because of optee-rng

2022-12-23T08:26:11+00:00

Fixes optee-rng driver bind sequence in optee driver to print a warning
message but not report an error status when a optee-rng service driver
fails to be bound as the optee driver itself is still fully functional.

blk: Switch over to using uclass IDs

2022-09-16T15:05:16+00:00

We currently have an if_type (interface type) and a uclass id. These are
closely related and we don't need to have both.

Drop the if_type values and use the uclass ones instead.

Maintain the existing, subtle, one-way conversion between UCLASS_USB and
UCLASS_MASS_STORAGE for now, and add a comment.

drivers: tee: optee: discover OP-TEE services

2022-09-14T19:23:03+00:00

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.

drivers:optee:rpmb: initialize drivers of mmc devices in UCLASS_BLK for rpmb access

2022-06-06T22:01:21+00:00

CONFIG_MMC only initializes drivers for devices in UCLASS_MMC, we need
to initialize drivers for devices of type IF_TYPE_MMC in UCLASS_BLK as
well because they are the child devices of devices in UCLASS_MMC.  This
is required for feature RPMB since it will access eMMC in optee-os.

tee: optee: bind rng optee driver

2022-04-11T14:28:04+00:00

In U-Boot, the discovery of TA based on its UUID on the TEE bus is
not supported.

This patch only binds the driver associated to the new supported
OP-TEE TA = TA_HWRNG when this driver is enable.

tee: optee: sync cache on pre-reloc OP-TEE invocation

2021-07-23T11:13:25+00:00

This change ensures both U-Boot and OP-TEE see the same content
from shared memory when OP-TEE is invoked prior U-Boot relocation.

This change is required since U-Boot may execute with data cache off
while OP-TEE always enables cache on memory shared with U-Boot.
