6913c45239 arm64: dts: rockchip: Add core dts for RK3308 SOC
RK3308 is a quad Cortex A35 based SOC with rich audio
interfaces(I2S/PCM/TDM/PDM/SPDIF/VAD/HDMI ARC), which
designed for intelligent voice interaction and audio
input/output processing.

This patch add basic core dtsi file for it.

This is unused on cheza.  Delete the node to get ride of the reserved-
memory section, and to avoid the driver from attempting to load a zap
shader that doesn't exist every time it powers up the GPU.

This also avoids a massive amount of dmesg spam about missing zap fw:

bd227553ad arm64: KVM: Prevent speculative S1 PTW when restoring vcpu context
When handling erratum 1319367, we must ensure that the page table
walker cannot parse the S1 page tables while the guest is in an
inconsistent state. This is done as follows:

On guest entry:
- TCR_EL1.EPD{0,1} are set, ensuring that no PTW can occur
- all system registers are restored, except for TCR_EL1 and SCTLR_EL1
- stage-2 is restored
- SCTLR_EL1 and TCR_EL1 are restored

On guest exit:
- SCTLR_EL1.M and TCR_EL1.EPD{0,1} are set, ensuring that no PTW can occur
- stage-2 is disabled
- All host system registers are restored

37553941c6 arm64: KVM: Disable EL1 PTW when invalidating S2 TLBs
When erratum 1319367 is being worked around, special care must
be taken not to allow the page table walker to populate TLBs
while we have the stage-2 translation enabled (which would otherwise
result in a bizare mix of the host S1 and the guest S2).

We enforce this by setting TCR_EL1.EPD{0,1} before restoring the S2
configuration, and clear the same bits after having disabled S2.

1d8cd06af5 arm64: KVM: Reorder system register restoration and stage-2 activation
In order to prepare for handling erratum 1319367, we need to make
sure that all system registers (and most importantly the registers
configuring the virtual memory) are set before we enable stage-2
translation.

This results in a minor reorganisation of the load sequence, without
any functional change.

ee9d90be9d arm64: Fake the IminLine size on systems affected by Neoverse-N1 #1542419
Systems affected by Neoverse-N1 #1542419 support DIC so do not need to
perform icache maintenance once new instructions are cleaned to the PoU.
For the errata workaround, the kernel hides DIC from user-space, so that
the unnecessary cache maintenance can be trapped by firmware.

To reduce the number of traps, produce a fake IminLine value based on
PAGE_SIZE.

bfcef4ab1d arm64: psci: Reduce the waiting time for cpu_psci_cpu_kill()
In cases like suspend-to-disk and suspend-to-ram, a large number of CPU
cores need to be shut down. At present, the CPU hotplug operation is
serialised, and the CPU cores can only be shut down one by one. In this
process, if PSCI affinity_info() does not return LEVEL_OFF quickly,
cpu_psci_cpu_kill() needs to wait for 10ms. If hundreds of CPU cores
need to be shut down, it will take a long time.

Normally, there is no need to wait 10ms in cpu_psci_cpu_kill(). So
change the wait interval from 10 ms to max 1 ms and use usleep_range()
instead of msleep() for more accurate timer.

In addition, reducing the time interval will increase the messages
output, so remove the "Retry ..." message, instead, track time and
output to the the sucessful message.

a9d21d1517 Actions Semi ARM64 changes for v5.5:
Most of the basic infrastructure is completed for the ARM64 S900 SoC.
 It can now boot a distro from eMMC/uSD with mainline kernel. Below are
 the changes for this cycle (only S900):
 
 - Added MMC controller support for S900 SoC. There are 4 controllers in
   this SoC, each capable of accessing MMC cards as well as SDIO.
 - Added onboard eMMC and uSD support for 96Boards Bubblegum96 board based
   on S900. Since the MMC driver is not capable of supporting SDIO currently,
   it is not enabled for now. And with the absence of PMIC support, fixed
   regulators are used to model the power supply.
