Editing Talk:Patch data.pkg

Just a simple SCE pkg file. For decrypt it we need to use spkg keyset (for 3.56+ firmwares) or pkg keyset (for 3.55 or lower firmwares)

It seems follow same .spkg_hdr.1 file scheme: [[Spkg_hdr.tar|Spkg_hdr.tar, Signed Firmware Package headers]]

Using pkg keyset (for 3.55 or lower firmwares) it can't be decrypted, we need to use spkg keyset:
  ./scetool -v -i patch_data.pkg
