[PATCH 00/18] Synchronise LS1088A/Ten64 device tree with Linux

[Mathew McBride]

I am intensively working on updating the current
"production" Ten64 (NXP LS1088A) firmware from v2020.07 to
the latest U-Boot, with the hope of taking advantage of
bootstd/bootflow and other improvements.

One desire I have is to have U-Boot "supply" the device tree
which is used for EFI boot, rather than our current method of
reading the DTB from a flash partition with commands (sf read etc.)
and plugging that into the distroboot process.

Indeed, once we syncronise the U-Boot FDT with the Linux
one, the bootflow method "Just Works" with the control
FDT, without us having to plug an external FDT into the
process.

(Note: the bootstd conversion for Ten64 will be coming in
a later commit. The DTS on it's own is only one part of 
the puzzle)

The flow of this series is:
- Fix a crash I found in the U-Boot FDT fixup for Layerscape

  The previous U-Boot copy of the fsl-ls1088a.dts did not
  have direct alias to the "crypto" node, triggering a crash
  when FDT fixup tried to operate on it.

- Enable DM_SERIAL for Ten64 (mirrors how it was enabled for
  LS1088A-RDB and LS1088A-QDS recently)

- Move all U-Boot "tweaks" into a -u-boot.dtsi file.
  Each board will have it's own <boardname>-u-boot.dtsi,
  which includs the SoC-specific fsl-ls1088a-u-boot.dtsi.

- For all hardware that was in U-Boot's fsl-ls1088a.dtsi,
  and not in the "correct" place (under /soc), move them
  into /soc and adopt the Linux kernel definition.

  PCIe needed special treatment as it's U-Boot binding was
  slightly different, as well as different compatible strings
  (match a different U-Boot driver) for MDIO, USB and fsl-mc
  among others.

  At this point, Linux is able to boot on the Ten64
  using U-Boot's FDT (passed to it via EFI) with
  major hardware (Ethernet, USB, PCIe) functional.

- Finally, copy over the U-Boot fsl-ls1088a.dtsi with the
  Linux kernel version.
  They are now bit-for-bit identical, with the U-Boot tweaks
  contained externally.

- Similarly for the Ten64 DTS - fsl-ls1088a-ten64.dts
  is now identical to the kernel version.

This builds upon the recent conversion of the LS1088A
to DM_SERIAL[1]. I used a similar syncronisation for the LS1028A[2]
as a guide.
