firmware: zynqmp: Do not report error if node is already configured

2022-01-19T14:14:29Z

Power domain driver sends PM fragment to PMUFW. It is sent for every node which is listed in DT. But some nodes could be already enabled but driver is not capable to find it out. That's why it blinly sents request for every listed IP. When PMUFW response by XST_PM_ALREADY_CONFIGURED error code there is no need to show any error message because node is already enabled. That's why cover this case with message when DEBUG is enabled.

firmware: zynqmp: Move loading message to debug

2022-01-19T14:14:29Z

Power domain driver is using this function for every IP which is PD listed. This can end up with a lot of messages which end up in boot log. That's why show it only in EL3 as was used in past.

xilinx: firmware: Move dcache handling directly to pmufw load config

2022-01-05T09:22:02Z

Core function should make sure that data is stored properly that's why move cache operations directly to zynqmp_pmufw_load_config_object() to be able to call it from other functions.

firmware: scmi: Add OP-TEE transport

2021-11-23T18:54:43Z

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].

firmware: scmi: smccc transport: use plat data, not priv data

2021-11-23T18:53:03Z

Change SCMI smccc transport drivers to use platform data rather than private data for channel reference since it only stores platform data retrieved from the DT. Consequently the probe handler is replaced with a of_to_plat handler. Cc: Simon Glass Cc: Patrice Chotard Cc: Patrick Delaunay Signed-off-by: Etienne Carriere Reviewed-by: Patrick Delaunay
