[PATCH 0/3] arm64: dts: meson: add BL32 reserved region to Beelink g12b devices

[Christian Hewitt]

This resolves a long-running issue where Beelink GT-King/Pro and
GS-King-X wedge on boot or shortly after when booting from vendor
u-boot. In some distros the issue is often reported as triggered
by large file transfers to/from USB or SD cards. Reserving the
BL32 memory region prevents the issue.

[PATCH 1/3] arm64: dts: meson: add BL32 reserved-memory region to GT-King

[Christian Hewitt]

Add an additional reserved memory region for the BL32 trusted firmware
shipping in Beelink g12b devices. This fixes a long running issue with
boxes booting from Vendor u-boot where the board wedges during boot or
soon after due to the (un)reserved region being overwritten.

The BL32 is typically common for the SoC family, so this change should
probably go into the g12b.dtsi.  Or probably even
meson-g12-common.dtsi, which is where the BL31 reserved-memory is
described.

Hi Kevin,

Would you be okay with the same change applied to GX devices too? - I
normally have these two catch-all patches in my tree to deal with random
tv box hardware and it would be great to drop them:

Hi Kevin,

Would you be okay with the same change applied to GX devices too? - I
normally have these two catch-all patches in my tree to deal with random
tv box hardware and it would be great to drop them:

Sure, it has been done in a similar way for bl31:
https://github.com/torvalds/linux/commit/48e21ded0432ee1e2359d4143d7a6925cefee1b5

in a perfect work we wouldn't need this since mainline U-Boot does the job by reserving these
memory zones, but vendor u-boot exists and isn't avoidable.
