INSTALL_DTBS_PATH
|
||||||
|
-----------------
|
||||||
|
INSTALL_DTBS_PATH specifies where to install device tree blobs for
|
||||||
|
relocations required by build roots. This is not defined in the
|
||||||
|
makefile but the argument can be passed to make if needed.

INSTALL_DTBS_PATH

This variable specifies a prefix for relocations required by build
|
||||||
|
roots. It defines a place for installing the device tree blobs. Like
|
||||||
|
INSTALL_MOD_PATH, it isn't defined in the Makefile, but can be passed
|
||||||
|
by the user if desired. Otherwise it defaults to the kernel install
|
||||||
|
path.
