Add patches to support population IPL sections using BootLoaderSpec files instead of having them defined in the zipl.conf file. This allows to have a static zipl.conf file, and update the boot entries by just dropping BLS fragments files in a directory. In this configuration the grubby tool isn't used, and instead all needed tasks (copy kernel, generate an initramfs, copy BLS configs, etc) should be made by kernel-install scripts.

Subject: [PATCH] zipl: Return number of allocated tokens in scan_file()
|
|
|
|
The function returns 0 on success and a negative number on error but is
|
|
useful to know how many tokens were allocated. This will be used by the
|
|
BLS parsing code to determine if needs to allocate mor tokens or not to
|
|
parse the BLS fragments.
