From 2a068400fcef7b1563d60f294b584b728236307f Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Wed, 17 Apr 2013 01:00:53 +0200 Subject: x86,efi: Implement efi_no_storage_paranoia parameter commit 8c58bf3eec3b8fc8162fe557e9361891c20758f2 upstream. Using this parameter one can disable the storage_size/2 check if he is really sure that the UEFI does sane gc and fulfills the spec. This parameter is useful if a devices uses more than 50% of the storage by default. The Intel DQSW67 desktop board is such a sucker for exmaple.
