But alas, it did not.

So I ran the first two make commands as above but with
my KERNCONF=BOOT2 in the mix as well.  Built a toolchain
and all just fine.  And switched into a "buildenv" as well.

However:

    # make
    Warning: Object directory not changed from original /usr/src/sys/boot/arm/ixp425/boot2
    cc -O -pipe -mbig-endian -march=armv5te -D__XSCALE__ -DBOOT_STACK=0x200000-4  -I/usr/src/sys/boot/arm/ixp425/boot2/../../../common  -I/usr/src/sys/boot/arm/ixp425/boot2 -DFIXUP_BOOT_DRV -Os -ffreestanding  -I/usr/src/sys/boot/arm/ixp425/boot2/../../../..  -I/usr/src/sys/boot/arm/ixp425/boot2/../../../../arm  -DCPU_XSCALE_IXP425  -Wall -Waggregate-return   -Werror  -Wnested-externs  -Wpointer-arith -Wshadow -Wwrite-strings  -Wmissing-prototypes  -Wmissing-declarations -DBOOT_IXP425 -std=gnu99  -c arm_init.S

    arm_init.S: Assembler messages:

    arm_init.S:52: Error: bad instruction `entry(cpu_id)'
    arm_init.S:54: Error: bad instruction `ret'
    *** Error code 1

*sigh*

Trying to simply build a kernel in this "buildenv" didn't work.
Same results from either:

    # make KERNCONF=BOOT2 buildkernel
or
    # make TARGET_ARCH=arm TARGET_CPUTYPE=xscale TARGET_BIG_ENDIAN=true KERNCONF=BOOT2 buildkernel

Like this:

    # make TARGET_ARCH=arm TARGET_CPUTYPE=xscale TARGET_BIG_ENDIAN=true KERNCONF=BOOT2 buildenv
    Entering world for arm:arm
    # cd /usr/src/sys/boot/arm/ixp425/boot2
    # make
    Warning: Object directory not changed from original /usr/src/sys/boot/arm/ixp425/boot2

    arm_init.S:27:25: error: machine/asm.h: No such file or directory

    Stop in /usr/src/sys/boot/arm/ixp425/boot2.

So I tried to construct the tree as it would be after a buildkernel,
but that didn't go well at all.

Should it be trying to find the file /usr/src/sys/arm/include/asm.h ?

Thanks,
