Re: [PATCH] MdeModulePkg DxeCore: Show error message on unaligned FvImage issue

["Kinney, Michael D" <michael.d.kinney@intel.com>]

Jiewen,

Do you think it would be a good idea to add a similar DEBUG()
message in the HobLib when an FV HOBs are created?  There are 
other ways FV HOBs can be created, so I think the DEBUG() message
in this patch is very important, but getting a message when
the an FV HOB is created will make fixing the issue easier.

Thanks,

Mike
