From: EvanLloyd <evan.lloyd@arm.com>
Because of copy/paste effects, HdLcdArmVExpress.c contained a
table entry "LCD_BPP Bpp;" specifying the Bits per Pixel for each mode.
However, all modes are LCD_BITS_PER_PIXEL_24.
This change removes the table entry and related use of the field.

Or am I misreading that? [[Evan Lloyd]] It does modify some shared lines. In practice this change became obvious once the previous one had been made. I'm not sure I understand what benefit you see in changing the order. I am, however, sure of the cost of rework and re-test. Do you really need this order change?

If you or your team can use some help with the git trickery that makes it simple, I'm happy to assist. If you trust me, you can pick the result from https://git.linaro.org/people/leif.lindholm/edk2.git/log/?h=166_gop_v1 (but the whole point of this is that I don't understand the changeset up front, so I may have bungled something) If your project schedule does not include the time to rework and re-test patchsets, I'll have a strong word with your product manager :) > Do you really need > this order change? How would you feel about our rolling them both > together? Not ideal. One is trivial cleanup, the other is an API change - squashing them together makes it a lot less clear which is which, and hence a lot harder to perform any sensible level of code review. Also a heads up: when you rebase this series to edk2/master, you'll encounter a breakage caused by gArmPlatformTokenSpaceGuid.PcdArmLcdDdrFrameBufferSize being given the same TokenValue as (now upstream) gArmPlatformTokenSpaceGuid.PcdWatchdogCount. / Leif > Evan > > > > > / > > Leif > > > > > Contributed-under: TianoCore Contribution Agreement 1.1 > > > Signed-off-by: Girish Pathak <girish.pathak@arm.com> > > > Signed-off-by: Evan Lloyd <evan.lloyd@arm.com> > > > --- > > > > > > > > ArmPlatformPkg/ArmVExpressPkg/Library/HdLcdArmVExpressLib/HdLcdArm > > VExp > > > ress.c | 42 ++++++-------------- > > > 1 file changed, 13 insertions(+), 29 deletions(-) > > > > > > diff --git > > > > > a/ArmPlatformPkg/ArmVExpressPkg/Library/HdLcdArmVExpressLib/HdLcdAr > > mVE > > > xpress.c > > > > > b/ArmPlatformPkg/ArmVExpressPkg/Library/HdLcdArmVExpressLib/HdLcdAr > > mVE > > > xpress.c index > > > > > dc2c5fb89923304c46d137ec8eaefc9418548d06..2401cdb30cb7252964ce1f36 > > 3aa2 > > > 6d99933c09be 100644 > > > --- > > > > > a/ArmPlatformPkg/ArmVExpressPkg/Library/HdLcdArmVExpressLib/HdLcdAr > > mVE > > > xpress.c > > > +++ > > b/ArmPlatformPkg/ArmVExpressPkg/Library/HdLcdArmVExpressLib/HdLcdA > > > +++ rmVExpress.c > > > @@ -30,7 +30,6 @@ > > > > > > typedef struct { > > > UINT32 Mode;
