* [PATCH 1/1] ARM64: dts: meson-gxbb-odroidc2: linux,usable-memory

  To: linus-amlogic

After reading the fdt u-boot overwrites the reg property of the
memory node with <0x0 0x0 0x0 0x78000000>.

To override this setting we have to use the property
linux,usable-memory.

If the first 16MB of the 2GB physical memory are used by
the Linux kernel oops occur on the Odroid C2.

For the Odroid C2 this patch replaces
[RFT PATCH] ARM64: dts: meson-gxbb: Add reserved memory zone and
usable memory range

Hi Heinrich,

Thanks a lot for testing and pushing this patch, indeed I missed this point abou u-boot overwriting reg.

I will test this next week, and hopefully get these merged.
