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 respond= ed 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 t= he 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 st= ill be modified identically to how that's done with certificates. Making all this generic means each platform has a unified set of command li= ne services. Cisco uses x86/arm32/arm64/mips/powerpc , and it's nice to have a= ll the same features across platforms. >=20 > 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 suppo= se it could have something under Documentation/. The only part which could use mo= re documentation are the changes in 2/8 and 3/8. That feature is maybe confusi= ng and has limitations which are maybe not clear. Although the same limitation= exist for inserting certificates. >=20 > I don't know what is the expected merge patch for this work.
