If we use erase option we only delete DF until DF_HWINFO_START
./mch_flasher -m df -e
If we still want to erase everything we need to use the scrub option
./mch_flasher -m df -s

We should not have all switches around run the same host key.  This
removes the pre-generated host keys and fixes the generation at boot
time (/etc is volatile, so it is copied to /usr/etc as well).

The binary file commited here is the same as in binaries/: it is generated

Our /etc is in initramfs, so writing to /etc has no effect.
I could write to /usr/etc or just remove the thing. Since it was not
working and nobody complained, I remove it.

I was bored by repeated file names, so this uses WRS_KER and other
variables to host the "magic" name.

Similarly, the use of "-old" was inconsistent, and this uses the
same pattern for all files. Actually, it should be a function
to avoid repetitions. But I'm lazy and it is not.

The upgrade we may do now is by placing files in /update, with
magic names:

    - wrs-firmware.tar: is *must* include wrs-usr.tar.gz, because
      if this file exists /usr is recreated from scratch.

         - it may include zImage, wrs-initramfs.gz, barebox.bin
	 (this happens in released firmware files, so the boot loader
	 is being written twice, until we get rid of the sam-ba tools)

    - zImage: if present, the kernel is replaced

    - wrs-initramfs.gz: if present, the initramfs is replaced

    - barebox.bin: if presente, the boot loader is replaced

This means, in practice, that you may change the whole system or one
part at a time.  I suppose only we developers will use the "one part
at a time".

But the most important change is that barebox.bin is being replaced
during boot.  In v4.0 we didn't expect to ever replace barebox, but
then we found we needed it -- so let's provide for further updates.
OTOH at91boot is not replaced, and it is not expected to, ever.

Commit 91c22de9 replaced some barebox patches, but I forgot to remove
the old ones, so build fails.

This fixes the problem. Moreover, there is a typo, which is
now fixed.

PATCH SQUASH
Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

Standard JEDEC ID is only 24bits to identify a DF chip.
It also has an optional Extended Device Info (EDI) on bytes 4 and/or 5
that need to be read to differentiate some DF chips. (i.e, the
difference between AT45DB641E and AT45DB642D is made by byte 4).

The script to load the elf file at startup need to be improved but it
was a quick hack to have things works on SCB v3.3 and SCB v3.4.

I generated it with "mdev -s".

But then I removed /dev/mtd5 (we have /dev/mtd5ro and nothing more),
and most tty/pty files are removed as just overhead.

This removes some stuff from the developer's manual (was: "wrs-build")
and adds it to the user's manual.  The stuff is still far from being
perfect, but at least it makes sense and can be made better for release 5.

We now have a developer's manual, even if the content needs a little
shuffling around. We also describe other manuals even though we still miss
a user's manual, as of this commit.
