You're right that these don't fix the issue that I brought up. My impression is that there is no direct solution so far. But these are all excellent ideas and methods to improve the usability of the repo. I think that as much of Laszlo's idea #1, #2, #3, and #4 above can be used will be really helpful. -Jaben > Thanks > Laszlo > > > > > > > >>> The worst example is the patch with a delete and then some code change > (probably should be a series). > >> > >> You can tell this from the start of the diff for each file: > >> > >>> --- a/ArmPlatformPkg/ArmPlatformPkg-2ndstage.dsc > >>> +++ /dev/null , > >> > >> And also from the diffstat (if all '-' signs next to a file, nothing > >> was added, if anything was added, you'll see '+' also). > >> > >>>>>> ArmPlatformPkg/ArmPlatformPkg-2ndstage.dsc | 382 > >>>>>> -------------- > ---- > >>>>>> ArmPlatformPkg/ArmPlatformPkg-2ndstage.fdf | 263 ------------ > >>>>>> ArmPlatformPkg/ArmPlatformPkg.dsc | 445 > >>>>>> --------------------- > >>>>>> ArmPlatformPkg/ArmPlatformPkg.fdf | 320 > >>>>>> --------------- > >>>>>> .../ArmPlatformLibNull/ArmPlatformLibNull.c | 162 -------- > >>>>>> .../ArmPlatformLibNull/ArmPlatformLibNull.inf | 51 --- > >>>>>> .../ArmPlatformLibNull/ArmPlatformLibNullMem.c | 34 -- > >>>>>> .../ArmPlatformLibNull/ArmPlatformLibNullSec.inf | 47 --- > >> > >> And, yes, it should :) > >> > >> / > >> Leif > >> > >>>>>> -----Original Message----- > >>>>>> From: edk2-devel [mailto:[email protected]] On > Behalf Of > >>>>>> Ryan Harkin > >>>>>> Sent: Wednesday, February 03, 2016 9:10 AM > >>>>>> To: [email protected]; [email protected]; Leif > Lindholm > >>>>>> <[email protected]> > >>>>>> Cc: Ryan Harkin <[email protected]>; Ard Biesheuvel > >>>>>> <[email protected]> > >>>>>> Subject: [edk2] [PATCH v2 6/6] Revert "ArmPlatformPkg: Create an > ARM > >>>>>> Platform DSC / FDF / ArmPlatformLib template" > >>>>>> Importance: High > >>>>>> > >>>>>> This reverts commit > 12fcdcb83d8e91cb730db9252189269467b9ed73 > >>>>>> > >>>>>> The files added by the commit have never been used.
