@ -65,6 +65,22 @@ INSTALL_PATH
INSTALL_PATH specifies where to place the updated kernel and system map
images. Default is /boot, but you can set it to other values.
INSTALLKERNEL
--------------------------------------------------
Install script called when using "make install".
The default name is "installkernel".
The script will be called with the following arguments:
$1 - kernel version
$2 - kernel image file
$3 - kernel map file
$4 - default install path (use root directory if blank)
The implmentation of "make install" is architecture specific
and it may differ from the above.
INSTALLKERNEL is provided to enable the possibility to
specify a custom installer when cross compiling a kernel.
