Subject: [PATCH v3 3/3] [edk2-platforms] Silicon/Intel/FitGen: Support Startup ACM entries (Type 2) 0x200 Version
Date: Fri,  1 Jul 2022 23:10:05 +0800	[thread overview]
Message-ID: <20220701151005.189-3-jason1.lin@intel.com> (raw)
In-Reply-To: <20220701151005.189-1-jason1.lin@intel.com>

From: Jason1 Lin <jason1.lin@intel.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3959

As per FIT BIOS Specification 1.2 Rules, the size bytes (3 bytes) /
reserved byte (1 byte) / CheckSum byte (1 byte) in type 2 are
must-be-zero (MBZ).
These bytes could be override for the other usages.
This change is used to support the Type 02 (ACM) Ver. 0x200.

Command:
[-S <StartupAcmAddress StartupAcmSize>|<StartupAcmGuid>]
[-I <StartupAcmFMS StartupAcmFMSMask>]
[-V <StartupAcmVersion>]
