Re: Booting the FreeBSD kernel as an zImage file needs a patch upgrade ?.

@Warner Losh :

Can you explain where I should add the parameter "WITH_KERNEL_BIN" ? I
tried in several ways,but it is not accepted :

$ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7 buildkernel
WITH_KERNEL_BIN = wrong

$ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7 WITH_KERNEL_BIN
buildkernel = wrong

$ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7
DESTDIR=/build-xen WITH_KERNEL_BIN installkernel = wrong

$ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7
DESTDIR=/build-xen installkernel WITH_KERNEL_BIN = wrong

How is it ?
