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.
Tegra: memctrl_v2: pack TZDRAM base to RSVD55_SCRATCH
This patch saves the TZDRAM_BASE value to secure RSVD55
scratch register. The warmboot code uses this register to
restore the settings on exiting System Suspend.
Tegra186: mce: get the "right" uncore command/response bits
This patch corrects the logic to read the uncore command/response bits
from the command/response values. The previous logic tapped into incorrect
bits leading to garbage counter values.
This patch modifies the timeout loop to use udelay() instead of
mdelay(). This helps with the boot time on some platforms which
issue a lot of MCE calls and every mdelay adds up increasing the
boot time by a lot.
To accommodate scenarios where we want to use a UART baud rate other than
the default 115,200 allow the associated compiler definition to be set
via the K3_USART_BAUD build option by updating the platform make file.
Since the platform make file now also contains the default value (still
115,200), go ahead and remove the redundant definition from the platform
header file.

This is a pseudo-API command consisting of a wait processor status

waiting for the System Firmware to ACK either message.
This is needed as the K3 power down specification states the System
Firmware must wait for a processor to be in WFI/WFE before powering
it down. The current implementation of System Firmware does not provide
such a command. Also given that with PSCI the core to be shutdown is the
core that is processing the shutdown request, the core cannot itself wait
for its own WFI/WFE status. To workaround this limitation, we submit
a wait processor status command followed by the actual shutdown command.
The shutdown command will not be processed until the wait command has
finished. In this way we can continue to WFI before the wait command
status has been met or timed-out and the shutdown command is processed.
