The memory node in the FDT is overwritten by u-boot with the standard dtb files:

The u-boot on my device is the one that came stock likely this config - gxl_p281_v1.

A fixup routine overwrites the memory config reducing internal ram size by 128Mb on the top end. You can confirm by looking at the loaded device tree in linux.

The parameter linux,usable-memory frees the memory up for use:

With change:

[ 0.000000] Initmem setup node 0 [mem 0x0000000001000000-0x000000003fffffff]

vs

[ 0.000000] Initmem setup node 0 [mem 0x0000000001000000-0x0000000037ffffff]
