It would be more natural to use a 1K alignment for this entire section.

However, the UEFI GenFw program ratchets up its alignment
|

|
|
granularity to the maximum granularity discovered in its input file.
|
||
|
|
Using 1K-alignment perturbs the symbols, hindering debugging. Thus,
|

this section is simply padded out to the desired alignment and
|
||
|

declared to have a section alignment of only 32 bytes.
