What's Changed

AdvLoggerPkg: PeilessArm: Check if Buffer Is Already Valid @os-d (#911)

Change Details

Description

PeilessArm currently assumes it is setting up the adv logger buffer. However, an earlier phase may have initialized the buffer, such as StMM running before SEC is started.

This adds a check to see if the buffer is already valid and just inherits it if so.
