I found this text in EDK II:
Minimum length(in bytes) of the system preboot TCG event log area(LAML) -----------------------------------------------------------------------
For PC Client Implementation spec up to and including 1.2 the minimum log size is 64KB. (SecurityPkg/SecurityPkg.dec)
Why should ours be smaller?
