Revert the commit c0e032e0090d65 ("scripts/dtc: Update to upstream
|
|
version v1.4.3")
|
|
OpenWrt uses the dtc from the kernel also in u-boot, but when we compile
|
|
against kernel 4.9 we run into some errors because it is too old now.
|
|
Add the options only when they are supported to make it compatible with
|
|
dtc from kernel 4.9.
