rcar_gen3: drivers: cpld: fix power-off on reset
Method cpld_reset_cpu of bl31 is called from the Linux kernel and uses
GPIO6, GPIO2 pins as SPI bus lines to control the CPLD device. But in the
kernel GPIO6_8 pin are initialized to work in interrupt mode instead of
the input/output mode. This leads to the fact that the SPI bus becomes
non-functional. In this patch we switch the GPIO6_8 pin back to the
input-output mode.

Tegra: bpmp_ipc: IPC driver to communicate with BPMP firmware
This patch adds the driver to communicate with the BPMP firmware on Tegra
SoCs, starting Tegra186. BPMP firmware is responsible for clock enable/
disable requests, module resets among other things.
MRQ is short for Message ReQuest. This is the general purpose, multi channel
messaging protocol that is widely used to communicate with BPMP. This is further
divided into a common high level protocol and a peer-specific low level protocol.
The higher level protocol specifies the peer identification, channel definition
and allocation, message structure, message semantics and message dispatch process
whereas the lower level protocol defines actual message transfer implementation
details. Currently, BPMP supports two lower level protocols - Token Mail Operations
(TMO), IVC Mail Operations (IMO).
This driver implements the IMO protocol. IMO is implemented using the IVC (Inter-VM
Communication) protocol which is a lockless, shared memory messaging queue management
protocol.
The IVC peer is expected to perform the following as part of establishing a connection
with BPMP.
1. Initialize the channels with tegra_ivc_init() or its equivalent.
2. Reset the channel with tegra_ivc_channel_reset. The peer should also ensure that
BPMP is notified via the doorbell.
3. Poll until the channel connection is established [tegra_ivc_channel_notified() return
0]. Interrupt BPMP with doorbell each time after tegra_ivc_channel_notified() return
non zero.
The IPC driver currently supports reseting the GPCDMAand XUSB_PADCTL hardware blocks. In
future, more hardware blocks would be supported.

On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory

ti: k3: common: Add support for runtime detection of GICR base address
Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

Firmware must wait for a processor to be in WFI/WFE before powering

core that is processing the shutdown request, the core cannot itself wait

a wait processor status command followed by the actual shutdown command.
