[Buildroot] [PATCH v1 1/4] board/zynqmp/post-build.sh: auto-generate extlinux.conf

[Buildroot] [PATCH v1 1/4] board/zynqmp/post-build.sh: auto-generate extlinux.conf

[Neal Frager via buildroot]

This patch uses the BR2_ROOTFS_POST_SCRIPT_ARGS to auto-generate the
extlinux.conf file, so developers will only need to modify the
board_defconfig file to change the console and boot file system locations.

Why would you need append-redirection >> ? Afterall, you just tested
that the file did not already exist... Anyway, see below...

We try to avoid generating files in the source tree.

Instead, why not just:

    FILE="${BOARD_DIR}/extlinux.conf"
    if test -f "$FILE"; then
        install -m 0644 -D "${BOARD_DIR}/extlinux.conf" "${BINARIES_DIR}/extlinux.conf"
    else
        mkdir -p "${BINARIES_DIR}"
        cat <<-__HEADER_EOF >"${BINARIES_DIR}/extlinux.conf"
    TAB>label linux
    TAB>  kernel /Image
    TAB>  devicetree /system.dtb
    TAB>  append console=${CONSOLE} root=/dev/${ROOT} rw rootwait
    TAB>__HEADER_EOF
    fi

Note: the <<- rediretion removes leading TABs, so it is allows a nicer
indentation (so, replace TAB> above with an actual TAB, of course).

Also, please always evaluate variables using curly braces and quote the
expansion, like so:   "${foo}"   (in the here-document, quotes are not
needed, of course).

Eventualy, at the end of this series, the script will always be used for
boards that do not already have an extlinux.conf, the condition can be
dropped in a final patch, to just only keep the else part of the
condition, don't you think?

Regards,
Yann E. MORIN.

Right, but use "${FILE}" after -D.

It's amazing how I always have some more shell trick to learn from Yann! :-D

This patch as is has no effect without patch 3 where the extlinux.conf
file is actually removed. Thus, for the sake of commit atomicity, I
would squash patches 2+3 together.

Otherwise looks good. It's a nice cleanup, thank you!

Very good solution.  I was not aware of the <<- trick!  Thank you!

Ok, I will update this.

Yes, I will add a last patch to the set that removes the if statement leaving a more simple solution at the end.

Thank you for your review!

I just want to make sure I am not missing something.  I have changed the script to the following:

if test -f "${FILE}"; then
         install -m 0644 -D "${BOARD_DIR}/extlinux.conf" "${BINARIES_DIR}/extlinux.conf"

Is there another -D I need to add somewhere?

I didn't explain clearly, sorry. What I mean is quite trivial: you can
simplify this:

  install -m 0644 -D "${BOARD_DIR}/extlinux.conf" ...

with this:

  install -m 0644 -D "${FILE}" ...

Ah, I see.  Yes, that would have been another simplification.
