fdtdec: fix parsing 'reg' property with zero value in '#size-cells'
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.
Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).
