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.

tee: optee: Change printing during optee_probe

2021-04-12T21:44:55+00:00

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.

validated however the commands (enable, provision) executed by the TEE
are assumed to always succeed.

drivers: tee: i2c trampoline driver

2021-02-16T16:48:20+00:00

This commit gives the secure world access to the I2C bus so it can
communicate with I2C slaves (typically those would be secure elements
like the NXP SE050).

A similar service implementation has been merged in linux:
c05210ab ("drivers: optee: allow op-tee to access devices on the i2c
bus")

dm: core: Access device ofnode through functions

2021-01-05T19:24:41+00:00

At present ofnode is present in the device even if it is never used. With
of-platdata this field is not used, so can be removed. In preparation for
this, change the access to go through inline functions.

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.
