    You can't get a tablet with a decent SoC anymore, it would seem. They're all powered by MediaTek or, more recently, Unisoc
    Are they?
    Samsung Galaxy Tab S7/S7+/S7 FE - Qualcomm Snapdragon 865+ or 750G (FE)
    Samsung Galaxy Tab A7 10.4 - Qualcomm SM6115 Snapdragon 662
    Lenovo Xiaoxin Pad Pro 12.6 - Qualcomm Snapdragon 870
    Lenovo Tab P11 5G/Tab P12 Pro - Qualcomm Snapdragon 750G
    I found plenty more from this year, just don't want to spam

      UEFI is not a boot standard, it's an operating system. By the way, UEFI for ARM exists and many ARM based server boards use it.

      Instead, every device has its own particular boot method, and most of the time only the manufacturer's kernel works on it.
      x86-64 boards also have their own boot method and that's why UEFI needs to be ported for the specific board, and the boards have it flashed on a chip.

      Most ARM boards have either u-boot (which supports the EFI standard if that's what you want) or coreboot (chromeos devices). What you want is ARM devices that are designed to boot from an external device so you can run an installer for the operating system or your choice.

        The old Tegra GPU was never fully reverse engineered. They never released any docs for it.

          For ARM boards with an upstream device tree it's really easy to get Barebox bootloader running. Barebox was formerly known as U-Boot v2 and no longer uses the hacky C board code style init as we see in U-Boot.

            The vast majority of non-open source embedded arm platforms i have messed with do in fact use uefi under the hood and boot with a (likely) modified version of tianocore. A prime example of this is samsung phones.

              Only the A7 is semi-decent from that list. The rest are just too expensive. Lenovo means basically no updates (other than security), Samsung comes with all the Samsung crap you can neither uninstall nor disable. Not to mention their stubborn policy of not supporting adoptable storage.

                Your initial statement was about getting devices with decent SOCs that are not Mediatek or Unisoc. Now that numacross pointed a (very small) example of devices using other SOCs, you are talking about device manufacturers not updating their stock android operating systems. If you want a manufacturer that update their software decently you have a very short list of options: google, apple, fairphone?, nokia?... But anyway nothing to do with the SOC used.

                  In my mind, a decent tablet includes timely updates among other things. It's certainly not the only criterion.

                    TF101's were nice with the docking station, but they all had problems with the video ribbon cable coming loose over time and many hit the refurb market.

                    Mine survived longer after I got a hold of an excellent 3rd party ROM until the lithium polymer batteries gave up. Replacements were $75 on AliXpress but not worth it by that time.
