I did not think about it this way. It's because I've submitted this so many times. I guess I assume everyone knows what it is. > And that info is sorely missed.

The limitation is that you can't append and prepend to the command line at the same time in any of the architectures. Having access to both allows OEMs to deal with broken bootloaders which can't easily be upgraded. Others have responded that they also use these patches for this same reason. In 2/8 and 3/8 I modify the insert-sys-cert tool to allow modification of the command line append and prepend after the build. This allow for an SDK provided with a binary kernel and for the command line append/prepend to still be modified identically to how that's done with certificates. Making all this generic means each platform has a unified set of command line services. Cisco uses x86/arm32/arm64/mips/powerpc , and it's nice to have all the same features across platforms. > > I see the patchset updates nothing under Documentation/. Should it do > so? Could it do so? The only documentation is Kconfig descriptions and commit messages. I suppose it could have something under Documentation/. The only part which could use more documentation are the changes in 2/8 and 3/8. That feature is maybe confusing and has limitations which are maybe not clear. Although the same limitation exist for inserting certificates. > > I don't know what is the expected merge patch for this work.
