From: Alexander Graf Date: Mon, 28 Jan 2019 13:35:29 +0000 (+0100) Subject: mkimage: Clarify file alignment in efi case X-Git-Tag: grub-2.04-rc1~66 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9223eff8f8025511938c7eec908d60bdaa74106a;p=thirdparty%2Fgrub.git mkimage: Clarify file alignment in efi case There are a few spots in the PE generation code for EFI binaries that uses the section alignment rather than file alignment, even though the alignment is really only file bound. Replace those cases with the file alignment constant instead.
