The switch to per-process address spaces erroneously dropped the check which validated that the command buffer is mapped through the linear apperture as required by the hardware. This turned a system misconfiguration with a helpful error message into a very hard to debug issue. Reinstate the check at the appropriate location.

Instead of just raising irq0 for all the cores, we mask the irq0 for all the non-target cores, this way waking up only the core we want. All of this is done now in TF-A. Also, since this new workaround doesn't need the IOMUX_GPR1 register here in kernel, the IOMUX_GPR reg entry inside the gic dts node can be removed. In order for this to work, the following commit is needed in TF-A: 0e91ff59720d0756 ("MLK-21399 plat: imx8mq: gpc: Workaround for ERR11171") Signed-off-by: -

The TPS65132B5 needs DSI_BIAS_EN for I²C to work but having it ENP/ENN enabled via the avdd/avee dt nodes would not work since those regulators won't be enabled before I²C is set up - which makes sense from a driver point of view. So to ensure DSI_BIAS_EN is always enabled before the driver is probed squash it in as a gpio enabled regulator between reg_vsys_3v4 and the TPS65132B5 which is how this gpio works after all.
