There may be a chance that board specific fix_fdt() will change the size of FDT
blob so it's safe to call reserve_fdt() after fix_fdt() otherwise global data (gd) will overwrite with FDT blob values.

Maybe you can add the fix tag if it is caused by this. Fixes: a8492e25ac71 ("riscv: Expand the DT size before copy reserved memory node")

Good suggestion, will update in v2. Thanks for the review.
I tend to disagree. The ordering issue is there for a long time and not introduced by a8492e25ac71 so "Fixes" tag is not accurate.
It's just a8492e25ac71 triggered the bug, not introduced the bug.
