…needed

Exit code which will be 0 if up to date, and 2 if a firmware update would have occurred.
Also the new commits will be printed to stdout

Stop rpi-update deleting dt-blob.bin

dt-blob.bin is used to configure a platform's pin settings and clock settings and must not be changed when we do an rpi-update.  This is a function of the platform rather than a function of the operating system and therefore shouldn't be removed

Update README.md

Upon installation of the tool, the command executed writes rpi-update to /usr/bin detailing a 301 error, indicating the source of the update has changed to https://raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update. This address change has been reflected in the proposed file change.

Small header tidyup

See: #134

This removes the requirement for git. We never make use of partial git updates,
and it is quicker to download the tarball with curl than use git.

Also piping the curl output into tar is quicker than downloading then un-tarring.

Remove the verbose options from the copies (they don't fail, slow down the copies
and swamp any more useful output messages).

By default delete /root/.rpi_firmware (as it's easy to recreate). Use
SKIP_REPODELETE=1 if you want to keep it.

Add option SKIP_BACKUP=1 if you don't want a backup of old firmware and modules.

May solve issues like #65

Add support for pre/post install scripts and Device Tree Blobs

Separate updating of vc_libs and sdk, allow sdk to be skipped

Added a new $WORK_PATH variable

Useful if you don't want to write files directly into /root

Ensure all string variables are fully quoted

Status message updates

Remove $GITCMD variable

Make it clearer that "modules" actually means "kernel modules", and display a message while extracting tarball (which can take a while).

small tidyup

After commit c5d159c $GITCMD is only used once, so 'inline it', which also allows us to get rid of the 'eval' call.

Slight tweak to the "startup logic"

Replace usages of $FW_PATH/.firmware_revision with a $FW_REVFILE variabl...

Remove embedded shebang

This fixes #102  (which would also get triggered if you rpi-updated to a specific revision, and then later tried rpi-updating to the latest revision)
