Upstream-Description:
zipl/boot: add secure boot trailer
This patch enhances the zipl stage3 loader image adding a
trailer as
required for secure boot by future firmware versions.
Note: with the change in this patch the padding via objcopy
command line
options is replaced by padding via linker script directives
with the
same effect.
