arm: dts: am33xx: Sync dts with Linux 4.20.0
This patch synchronizes the am33xx SoC specific files with those from
Linux 4.20.0. Hence all board maintainers of am33xx based boards are
on the cc list.
The main purpose of this patch is to prevent further diverging of the
dts files from U-Boot and those from Linux. It aims to set the stage
for the synchronization of board specific dts files. Example: I'm the
maintainer of the PDU001 board: once this patch is applied successfully
I will make changes to the board specific dts file in Linux only and
then post a patch with a copy of this exact dts file to U-Boot. This
will make U-Boot and Linux remain in sync.
The stumbling block of https://patchwork.ozlabs.org/patch/943627 was
removed by the patch https://patchwork.ozlabs.org/patch/962428 from
Lokesh Vutla (many thanks!). This omap-serial driver allows using the
Linux am33xx.dtsi file in U-Boot.
Other changes to dts and dtsi files made by this patch are mainly to
prevent _new_ warnings during the build process. Especially the warning
at pinmux@800 stating 'unnecessary #address-cells/#size-cells without
"ranges" or child "reg"' was not removed. This warning is a good example
showing the benefit of the synchronization: if it needs to be fixed it
will be fixed in Linux and ported back to U-Boot.
Buildman reports all 46 am33xx SoC based boards to build fine, with
warnings of course. Nevertheless this patch should be tested thoroughly
on as many boards as possible to prevent any collateral damage.

clk: Allow clock defaults to be set during re-reloc state for SPL only
In commit
e5e06b65ad65 ("clk: Allow clock defaults to be set also
during re-reloc state") the earlier guard against setting clock
defaults in pre-reloc state was removed. While it is easy to filter
'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS,
no such mechanism exists for the pre-reloc stage of the full U-Boot.
With the default defconfig for the RK3399-Q7 (which filter the
'assigned-clocks' property for the DTS used by SPL anyway), this
caused a pause during startup of the full U-Boot stage that lasted for
almost 10s (due to the CPU not having been clocked up yet).
This reintroduces the guard from commit
f4fcba5c5baa ("clk: Allow
clock defaults to be set also during re-reloc state") and extends it
to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will
now run in pre-reloc state for SPL, but only after reloc for the full
U-Boot.

SPI flash based MTD devs can be registered/unregistered at any time
through the sf probe command or the spi_flash_free() function.
This commit does not try to fix the root cause as it would probably
require rewriting most of the code and have an mtd_info object
instance per spi_flash object (not to mention that the the spi-flash
layer is likely to be replaced by a spi-nor layer ported from Linux).
Instead, we try to be as safe as can be by checking the code returned
by del_mtd_device() and complain loudly when there's nothing we can
do about the deregistration failure. When that happens we also reset
sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks
so that -ENODEV is returned instead of hitting a NULL pointer
dereference exception when the MTD instance is later accessed by a user.

mtd: sf: Unregister the MTD device prior to removing the spi_flash obj
The DM implementation of spi_flash_free() does not unregister the MTD
device before removing the spi dev object. This leads to a use-after-free
bug when the MTD device is later accessed by a MTD user (observed when
attaching the device to UBI after env_sf_load() has called
spi_flash_free()).
Implement ->remove() and call spi_flash_mtd_unregister() from there.

mtd: Don't stop MTD partition creation when it fails on one device
MTD partition creation code is a bit tricky. It tries to figure out
when things have changed (either MTD dev list or mtdparts/mtdids vars)
and when that happens it first deletes all the partitions that had been
previously created and then creates the new ones based on the new
mtdparts/mtdids values.
But before deleting the old partitions, it ensures that none of the
currently registered parts are being used and bails out when that's
not the case. So, we end up in a situation where, if at least one MTD
dev has one of its partitions used by someone (UBI for instance), the
partitions update logic no longer works for other devs.
Rework the code to relax the logic and allow updates of MTD parts on
devices that are not being used (we still refuse to updates parts on
devices who have at least one of their partitions used by someone).

x86_64-gcc-8.1.0-nolibc-aarch64-linux.tar.xz

e.g.:
x86_64-gcc-7.3.0-nolibc_aarch64-linux.tar.xz
Notice that the first pattern has dashes throughout, while the second has
dashes throughout except just before the target architecture which has an
underscore.
The "dash throughout" versions from kernel.org are:
8.1.0, 6.4.0, 5.5.0, 4.9.4, 4.8.5, 4.6.1
while the "dash and underscore" versions from kernel.org are:
7.3.0, 4.9.0, 4.8.0, 4.7.3, 4.6.3, 4.6.2, 4.5.1, 4.2.4

e.g.:
gcc-8.1.0-nolibc/aarch64-linux/
The first entry of the hexagon toolchain, however, is:
gcc-4.6.1-nolibc/
This causes the buildman logic in toolchain.py::ScanPath() to not be able to
find the "*gcc" executable since it looks in gcc-4.6.1-nolib/{.|bin|usr/bin}
instead of gcc-4.6.1/hexagon-linux/{.|bin|usr/bin}. Therefore when buildman
tries to download a set of toolchains that includes hexagon, the script fails.

We cannot fix this in general, but we can reduce the effect by doing a

(BBL or equivalent) uses memory range in 0x80000000 to
0x80200000. Due to this, we cannot use 0x80000000 as
SYS_TEXT_BASE when running in S-mode. Instead for S-mode,
we use 0x80200000 as SYS_TEXT_BASE.
Even Linux RISC-V kernel ignores/reserves memory range
0x80000000 to 0x80200000 because it runs in S-mode.

riscv: Add kconfig option to run U-Boot in S-mode
This patch adds kconfig option RISCV_SMODE to run U-Boot in
S-mode. When this opition is enabled we use s<xyz> CSRs instead
of m<xyz> CSRs.
It is important to note that there is no equivalent S-mode CSR
for misa and mhartid CSRs so we expect M-mode runtime firmware
(BBL or equivalent) to emulate misa and mhartid CSR read.
In-future, we will have more patches to avoid accessing misa and
mhartid CSRs from S-mode.
