2021-11-28test/py: Relax the naming rules for unit testsSimon Glass
At present the collection function used by pytest is quite strict on the naming of the functions it detects. In particular it requires the name of the test to be repeated in the function name. This is not enforced anywhere else, but instead the tests are silently omitted from the pytest run. This affects a few dozen tests. The rule does not seem to have any particular purpose. Relax it, so that all tests that use the UNIT_TEST() macro will run, regardless of the name of the test function. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-11-28dm: core: Add a way to obtain a string listSimon Glass
At present we support reading a string list a string at a time. Apart from being inefficient, this makes it impossible to separate reading of the devicetree into the of_to_plat() method where it belongs, since any code which needs access to the string must read it from the devicetree. Add a function which returns the string property as an array of pointers to the strings, which is easily used by clients. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-11-28dm: core: Fix handling of uclass pre_unbind methodSimon Glass
This method is currently called after the platform data has been freed. But the pre_unbind() method may wish to access this, e.g. to free some data structures stored there.

- A set of SCMI and TEE related updates
2021-11-23firmware: scmi: Add OP-TEE transportEtienne Carriere
This change implements an SCMI transport for agent interfacing the OP-TEE SCMI service. OP-TEE provides an SCMI PTA (Pseudo-TA) for non-secure world to send SCMI messages over an identified channel. The driver implemented here uses a SMT shared memory for passing messages between client and server. The implementation opens and releases channel resources for each passed SCMI message so that resources allocated (sessions) or registered (shared memory areas) in OP-TEE firmware are released for example before relocation as the driver will likely allocate/register them back when probed after relocation. The integration of the driver using dedicated config switch CONFIG_SCMI_AGENT_OPTEE is designed on the model posted to the U-Boot ML by Patrick Delaunay [1].

2021-11-23net: dsa: sja1105: add support for SGMIIVladimir Oltean
The list of ports which support SGMII depending on switch generation is available here: https://www.kernel.org/doc/html/latest/networking/dsa/sja1105.html#port-compatibility-matrix SGMII can either be used to connect to an external PHY or to the host port. In the first case, the use of in-band autoneg is expected, in the last, in-band autoneg is expected to be turned off (fixed-link). So the driver supports both cases. SGMII support means configuring the PCS and PMA. The PCS is a Synopsys Designware XPCS, in Linux this has a separate driver but here it is embedded within the sja1105 driver. If needed it can be taken out later, although we would need a UCLASS_PCS for it, which we don't have atm. Nonetheless, I did go all the way to export an internal MDIO bus for PCS access, because it is nice to be able to debug the PCS through commands such as: => mdio read ethernet-switch@1-pcs 4 1f.0 Reading from bus ethernet-switch@1-pcs PHY at address 4: 31.0 - 0x1140 The internal MDIO bus is not registered with DM because there is no udevice on it, as mentioned. But the XPCS code can still be ripped out, as needed. I did not add support for 2500base-x because I do not expect this interface type to be used as a boot source for anybody, it would just add unnecessary bloat.

2021-11-23net: dsa: add driver for NXP SJA1105 L2 switchVladimir Oltean
The SJA1105 driver is largely reused from Linux. Its programming model is that it is blank out of reset, and it waits for a static configuration stream over SPI, which contains all runtime parameters (it has no notion of "default values"). Keeping a binary array for the configuration stream would have meant that aspects such as the CPU port and the MAC speeds could have not been configured easily, and would have been static and board-dependent. Live-patching the binary array means recalculating the static config table CRCs, which is not a fun process. So we create an abstraction over the static config tables, using the packing API, same as in Linux. The tables are kept as C structures, and the binary configuration stream is constructed on-the-go, with CRC and all. All static config tables instantiated in this driver are mandatory. The hardware reference manual can be found at: https://www.nxp.com/docs/en/user-guide/UM10944.pdf For tagging, a simplified version of tag_8021q from Linux is used. The VLAN EtherType is the same (0xdadb) but since we don't want switching in U-Boot, there is no reason to have a TX VLAN and an RX VLAN for each port. We just need the RX VLANs to act as the unique pvid of each front-panel port, to decode the switch port number. The RX VLAN is used for both RX and TX. The device tree bindings are the same as in Linux. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
