7e5b734ae7 kboot: Rework how kboot_prepare_fw() works 
Now it just builds and returns the firmware portion of the initramfs. It
is up to the caller to prepend it to the user-supplied initramfs, unless
no initramfs was set, in which case kboot_prepare_dt will implicitly
call kboot_prepare_fw.

Then make the payload code and linux.py handle this properly.

9fae977161 m1n1.fw.dcp.ipc: Add SizedArray/SizedBytes to handle data/len pairs 
The serialization always uses fixed-length arrays. These wrappers use a
length argument (possibly coming later in the args) to size the fields
so that the arrays are truncated or padded to the right length as
returned to the user.

6afe9ebaf9 kboot: move SEPFW to initrd before booting 
Bootstrapping SEPOS requires to setup a scratch buffer and
will have to be handled by the final OS. We pass along
the firmware image by appending it to the initramfs.

6adf0c692c mini.trace.asc: Don't log handled messages

handled the message (True if so). In that case, printing the underlying
mailbox traffic is redundant, so let's hide it.
