After rework of lib/fdtdec.c by:
commit: 02464e3 fdt: add new fdt address parsing functions
the function fdtdec_get_addr() doesn't work as previous, because the implementation assumes that properties '#address-cells' and '#size-cells' are equal to 1, which can be not true sometimes.
The new API introduced fdtdec_get_addr_size_auto_parent() for the 'reg' property parsing, but the implementation assumes, that #size-cells can't be less than 1.
This causes that the following children's 'reg' property can't be reached:
parent@0x0 { #address-cells = <1>; #size-cells = <0>; children@0x100 { reg = < 0x100 >; }; };
Change the condition value from '1' to '0', which allows parsing property with at least zero #size-cells, fixes the issue.
Now, fdtdec_get_addr_size_auto_parent() works properly.

Applied to u-boot-fdt, thanks!
