Basic StarFive JH7100 RISC-V SoC support

This adds support for the StarFive JH7100 RISC-V SoC. The SoC has many
devices that need non-coherent DMA operations to work which isn't
upstream yet[1], so this just adds basic support to boot up, get a
serial console, blink an LED and reboot itself. Unlike the Allwinner D1
this chip doesn't use any extra pagetable bits, but instead the DDR RAM
appears twice in the memory map, with and without the cache.

The JH7100 is a test chip for the upcoming JH7110 and about 300 BeagleV
Starlight Beta boards were sent out with them as part of a now cancelled
BeagleBoard.org project. However StarFive has produced more of the
JH7100s and will be selling VisionFive boards with them soon[2].

exactly 16 * 115200Hz and many other common bitrates. Trying this will

pinctrl: starfive: Add pinctrl driver for StarFive SoCs

Add a combined pinctrl and GPIO driver for the JH7100 RISC-V SoC by
StarFive Ltd. This is a test chip for their upcoming JH7110 SoC, which
is said to feature only minor changes to these pinctrl/GPIO parts.

For each "GPIO" there are two registers for configuring the output and
output enable signals which may come from other peripherals. Among these
are two special signals that are constant 0 and constant 1 respectively.
Controlling the GPIOs from software is done by choosing one of these
signals. In other words the same registers are used for both pin muxing
and controlling the GPIOs, which makes it easier to combine the pinctrl
and GPIO driver in one.

I wrote the pinconf and pinmux parts, but the GPIO part of the code is
based on the GPIO driver in the vendor tree written by Huan Feng with
cleanups and fixes by Drew and me.

tee: handle lookup of shm with reference count 0

Since the tee subsystem does not keep a strong reference to its idle
shared memory buffers, it races with other threads that try to destroy a
shared memory through a close of its dma-buf fd or by unmapping the
memory.

In tee_shm_get_from_id() when a lookup in teedev->idr has been
successful, it is possible that the tee_shm is in the dma-buf teardown
path, but that path is blocked by the teedev mutex. Since we don't have
an API to tell if the tee_shm is in the dma-buf teardown path or not we
must find another way of detecting this condition.

Fix this by doing the reference counting directly on the tee_shm using a
new refcount_t refcount field. dma-buf is replaced by using
anon_inode_getfd() instead, this separates the life-cycle of the
underlying file from the tee_shm. tee_shm_put() is updated to hold the
mutex when decreasing the refcount to 0 and then remove the tee_shm from
teedev->idr before releasing the mutex. This means that the tee_shm can
never be found unless it has a refcount larger than 0.

while bitwise operations do not.

In this instance, tegra_fuse_read_spare() is not semantically returning
a boolean, it is returning a bit value. Use u32 for its return type so
that it can be used with either bitwise or boolean operators without any
warnings.

ARM: dts: gemini: NAS4220-B: fis-index-block with 128 KiB sectors

Steven Maddox reported in the OpenWrt bugzilla, that his
RaidSonic IB-NAS4220-B was no longer booting with the new
OpenWrt 21.02 (uses linux 5.10's device-tree). However, it was
working with the previous OpenWrt 19.07 series (uses 4.14).

|[    5.548038] No RedBoot partition table detected in 30000000.flash
|[    5.618553] Searching for RedBoot partition table in 30000000.flash at offset 0x0

|...
|[    7.039504] Waiting for root device /dev/mtdblock3...

The provided bootlog shows that the RedBoot partition parser was
looking for the partition table "at offset 0x0". Which is strange
since the comment in the device-tree says it should be at 0xfe0000.

Further digging on the internet led to a review site that took
some useful PCB pictures of their review unit back in February 2009.
Their picture shows a Spansion S29GL128N11TFI01 flash chip.

>From Spansion's Datasheet:
"S29GL128N: One hundred twenty-eight 64 Kword (128 Kbyte) sectors"
Steven also provided a "cat /sys/class/mtd/mtd0/erasesize" from his
unit: "131072".

With the 128 KiB Sector/Erasesize in mind. This patch changes the
fis-index-block property to (0xfe0000 / 0x20000) = 0x7f.

ARM: dts: spear3xx: Use plgpio regmap in SPEAr310 and SPEAr320

Resources used by plgpio and pinmux are conflicting on SPEAr310
and SPEAr320.

Use the newly introduced regmap property in plgpio node to use
pinmux resources from plgpio and so avoid the conflict.
