arm64: dts: rockchip: add rk3588 pcie and php IOMMUs
The mmu600_pcie is connected with the five PCIe controllers.
The mmu600_php is connected with the USB3 controller, the GMAC
controllers, and the SATA controllers.
See 8.2 Block Diagram, in rk3588 TRM (Technical Reference Manual).
The IOMMUs are disabled by default, as further patches are needed to
program the SID/SSIDs in to the IOMMUs.
Additionally, the IOMMU correctly triggers an IOMMU fault when
a PCIe device performs a write (since the device hasn't been
assigned a SID/SSID):
arm-smmu-v3 fc900000.iommu: event 0x02 received:
arm-smmu-v3 fc900000.iommu: 0x0000010000000002
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
While this doesn't provide much value as is, having the devices as
disabled in the device tree will allow developers to see that the rk3588
actually has IOMMUs on the SoC.

arm: move _end to linker symbols
commit 6e2228fb052b ("Merge patch series "Clean up arm linker scripts")
was cleaning up linker scripts for armv7 and v8 but was leaving
_end and __secure_stack_start/end.
commit d0b5d9da5de2 ("arm: make _end compiler-generated")
was moving _end to be compiler generated. _end is defined as c variable
in its own section to force the compiler emit relative a reference.
However, defining those in the linker script will do the same thing
since [0].
So let's remove the special sections from the linker scripts, the
variable definitions from sections.c and define them as a symbols.
It's worth noting that _image_binary_end symbol is now redundant and
can be removed in the future.
When decompressing, it's possible that the algorithm only performs
a partial decompression.
This usually happens when CONFIG_SYS_BOOTM_LEN is too small for
the uncompressed image.
When that happens, image_decomp() returns an error and *load_end == load.
The error is then handled by handle_decomp_error().
handle_decomp_error() expects the number of uncompressed bytes in
uncomp_size but receives *load_end - load == load - load == 0.
Because of this, handle_decomp_error does not report the expected
"Image too large: increase CONFIG_SYS_BOOTM_LEN" error message.
Modify the image_decomp() logic to always report the decompressed size,
even when a partial decompression happened.

4GB 2GHz and 8GB 2GHz RAM.
The RAM size and speed grade is detected by the information
stored in the EEPROM on the SoM.

arm: imx8mp-phycore: move to OF_UPSTREAM
The PHYCORE_IMX8MP is used by the phyBOARD-Pollux. Migrate board to
OF_UPSTREAM. Linux kernel device tree for the board can be used as is,
corresponding U-Boot device tree files are removed. U-Boot tweaks are
kept unchanged.

board: toradex: verdin-imx8mm: add 4 GB lpddr4 memory support
Add support for MT53E512M32D1ZW-046 IT:C memory.
This 4 GB memory has 17 row bits instead of 16 and requires 380 ns of
tRFC (tRFCab) instead of 280 ns due to increased channel density to 16 Gb.
Both modifications are retro-compatible with previous memories.
