Computing the baud rate register value requires knowledge of the hardware sampling rate. This information is currently encoded in a baud rate calculation algorithm ID passed through platform data. However, it can be derived from the port type directly in most cases. Compute the sampling rate internally in the driver if the baud rate calculation algorithm ID isn't specified, and allow platforms to override the sampling rate through platform data in special cases (this is only required for SCIFA ports on sh7723 and sh7724, the reason needs to be investigated).

Value 0 of the sense selection field of CONFIG_n register means "disable event detection" and serves in irqc_sense[] for marking the invalid values of the IRQ type (by just omitting initializers). There is no need for INTC_IRQ_SENSE_VALID and hence INTC_IRQ_SENSE() as all field values matching to the valid IRQ types are non-zero anyway. Signed-off-by:

The break timer accesses hardware registers and thus requires the port to be enabled. It currently ensures this by enabling the port at the beginning of the timer handler, and disabling it at the end. However, the enable/disable operations call the runtime PM sync functions, which are not allowed in atomic context. The current situation is thus broken. This change relies on non-atomic code to enable/disable the port. The break timer will only be started from the IRQ handler, which already runs with the port enabled. We just need to ensure that the port won't be disabled with the timer running, and that's easily done by just cancelling the timer in the port disable function. Signed-off-by:

Not all Tegra devices can set the CPU reset handler in the same way. In particular, devices using a TrustZone secure monitor cannot set it up directly and need to ask the firmware to do it.

Trusted Foundations is a TrustZone-based secure monitor for ARM that can be invoked using the same SMC-based API on supported platforms. This patch adds initial basic support for Trusted Foundations using the ARM firmware API. Current features are limited to the ability to boot secondary processors. Note: The API followed by Trusted Foundations does *not* follow the SMC calling conventions. It has nothing to do with PSCI neither and is only relevant to devices that use Trusted Foundations (like most Tegra-based retail devices). Signed-off-by:
