This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").

The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:

  ddr3: add missing txsdll parameter
  ddr3: fix tfaw timimg parameter
  ddr3: fix trrd timimg parameter
  merge ddr3 topology header file with mv_ddr_topology one
  mv_ddr: a38x: fix zero memory size scrubbing issue

The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

    find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
        xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \
                 -UCONFIG_APN806 -UCONFIG_MC_STATIC \
                 -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
                 -UCONFIG_64BIT -UCONFIG_A3700 -UA3900 -UA80X0 \

- Various FAT fixes
- Hardware spinlock uclass
- DMA uclass
- Various am335x fixes
- DT resyncs for a number of TI platforms
- stm32 updates

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.

This patch enables CONFIG_BLK as well as CONFIG_DM_MMC for the PDU001
board. It depends on Patrice Chotard's patch 'power: regulator: denied
disable on always-on regulator' which prevents power cycling the vmmc
supply. Without this patch the board will not boot as vmmc is
unfortunately used by other board components, not just eMMC and micro SD
card. Furthermore my patch 'dts: am335x-pdu001: Fix polarity of card
detection input' is required to boot from external micro SD card. Without
this patch no SD card will be detected and hence booting will fail.

Currently k2 spi boot is broken as the image header
is getting copied to an invalid memory location

CONFIG_SYS_TEXT_BASE - sizeof (struct image_size)
which maps to 0xc000000 - 0x40 = 0xbffffc0 being a reserved
location.

We cannot change the CONFIG_SYS_TEXT_BASE address as the single
stage boots like UART boot will need the address to be 0xc000000
hence override the spl_get_load_buffer to have image_header
address as CONFIG_SYS_TEXT_BASE aka 0xc000000

In commit e5e06b65 ("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 f4fcba5c ("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.

The cluster size specifies how many sectors make up a cluster.  A
cluster size of zero makes no sense, as it would mean that the
cluster is made up of no sectors.  This will later lead into a
division by zero in sect_to_clust(), so better take care of that
early.

The MAX_CLUSTSIZE define can reduced using a define to make some
room in low-memory system.  Unfortunately if the code reads a
filesystem with a bigger cluster size it will overflow the buffer.
