a213289953 board: ti: k3: Remove need for CFG_SYS_SDRAM_BASE
The base address of extended DDR does not change across the K3 family.
Setting this per SoC is not needed. Remove this definition to help
remove the last bits from K3 include/configs/*.h files.

c90462e691 arm: mach-k3: Remove non-cached memory map areas
All normal memory areas should be mapped as such.

We added these un-cached holes in our memory map to hack around the
remoteproc driver missing the proper cache maintenance operations.

The problem is having these non-cached memory map areas causes stability
issues later in system operation due to the nature of the K3 coherency
architecture. Plus these are board specific carveouts and instead
should have been added at the board level, not here in the SoC common
code area.

Remove these non-cached memory map areas.

The problem is that the arm64 magic is checked before the image is
decompressed. However this is only part of it. The kernel_noload image
type doesn't work with compression, since the kernel is not loaded. So
this series deals with that by using an lmb-allocated buffer for the
uncompressed kernel.

Another issue is that the arm64 handling is done too early, before the
image is loaded. This series moves it to after loading, so that
compression can be handled.

A patch is included to show the kernel load-address, so it is easy to
see what is going on.

One annoying feature of arm64 is that the image is often copied to
another address. It might be possible for U-Boot to figure that out
earlier and decompress it to the right place, but perhaps not.

With all of this it should be possible to boot a compressed kernel on
any of the 990 arm64 boards supported by Linux, although I have only
tested two.

47256b040c board: stm32f469-disco: add support to display
Add support to Orise Tech OTM8009A display on stm32f469-disco board.

It was necessary to retrieve the framebuffer address from the device tree
because the address returned by the video-uclass driver pointed to a memory
area that was not usable.

451ae8daa2 ARM: dts: stm32: make the DSI clock usable by the clock driver
As described in [1], the "clocks" property contains "a phandle to the
clock device node, an index selecting between gated clocks (0) and other
clocks (1), and an index specifying the clock to use." The current version
of the clock driver, unlike the kernel, is currently able to properly
handle nodes with "clocks" properties with an index set to 0.

This patch is preparatory for future developments that require the use
of the DSI clock.

Set pllsaidivr only if the PLLSAIR output frequency is an exact multiple
of the pixel clock rate. Otherwise, we search through all combinations
of pllsaidivr * pllsair and use the one which gives the rate closest to

cfdbdf7842 ARM: imx: Update DRAM timings with inline ECC on Data Modul i.MX8M Plus eDM SBC
Import DRAM timings generated by the DDR tool 3.31 which introduce assorted
tweaks to the DRAM controller settings. Furthermore, enable DBI to improve
noise resilience of the DRAM bus by reducing the number of bit changes on
the bus.

Reduce the DRAM rate to 3600 MTps to remove all remaining correctable errors
reported by EDAC . It is not entirely clear why the slightly faster setting
does produce sporadic correctable errors, while this one does not, but this
could be related to simpler PLL setting at 3600 MTps.

Enable inline ECC which is necessary to detect ECC errors and collect
statistics by the EDAC driver in Linux. This reduces the DRAM size by
64 MiB for each 512 MiB of DRAM, so for a 4 GiB device the available
DRAM size becomes 3.5 GiB .
