Subject: [PATCH 2/2] zipl/boot: add secure boot trailer
|
|

MIME-Version: 1.0

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.
