2f123cbcf0 Staging: xgifb: fix bitwise vs logical bug
This is a static checker fix and not something I can test.  The intent
of the code here is to set some bit flags.  For a logical OR the ">> 1"
shift wouldn't make a difference.  So it should be using a bitwise OR.

6d12dae47e staging/xgifb: Cleanup vb_device_info struct

pXGINew_I2CDefinition
pCR2E
pCR2F
pCR46
pCR47
pCRD0
pCRDE
pSR40
pSR41

=== Remove the corresponding 'constants' ===
XGI330_RGBSenseData
XGI330_RGBSenseData2
XGI330_VideoSenseData
XGI330_VideoSenseData2
XGI330_YCSenseData

XG21_CR2E
XG21_CR2F
XG21_CR46
XG21_CR47
XG27_CRD0
XG27_CRDE
XGI330_OutputSelect

== Remove 'constant fields' and replace constant value with #define ==
pSR07 = XGI330_SR07 -> 0x18
pSR1F = XGI330_SR1F -> 0

pSR41 = XG27_SR41 ->0x00
pSR31 = XGI330_SR31 -> 0xc0
pSR32 = XGI330_SR32 -> 0xc0
SR25 = XGI330_sr25 -> 0 (we only use XGI330_sr25[0])

== Constant fields with 'dead' code: ==
pSoftSetting is set to XGI330_SoftSetting = 0x30
-> if (*pVBInfo->pSoftSetting & SoftDRAMType) is never true since
SoftDRAMType = 0x80
-> if (*pVBInfo->pSoftSetting & ModeSoftSetting) is never true since
ModeSoftSetting = 0x04
--> remove the code, remove pSoftSetting, remove XGI330_SoftSetting

pDVOSetting is set to XG21_DVOSetting = 0
-> if (((*pVBInfo->pDVOSetting) & 0xC0) == 0xC0) is never true
--> remove the code, remove pDVOSetting, remove XG21_DVOSetting

pXGINew_DRAMTypeDefinition is set to &XG40_DRAMTypeDefinition 0xFF
-> if (*pVBInfo->pXGINew_DRAMTypeDefinition != 0x0C) is always true
--> remove the if and remove pXGINew_DRAMTypeDefinition
remove XG40_DRAMTypeDefinition

== Replace pointer to unsigned char with unsigned char variable
and assign value of referenced pointer: ==
pSR21 -> SR21, remove XGI330_SR21
pSR22 -> SR22, remove XGI330_SR22
pXGINew_CR97 -> XGINew_CR97, remove XG20_CR97, XG27_CR97 and Z11m_CR97

03f76fc617 staging/xgifb: Replace delay lookup tables with constant values
For TV Devices:
The values taken from XGI_TVDelayList are always overwritten with the
values from XGI_TVDelayList2 since the if condition for using the values
from XGI_TVDelayList2 is identical with the check to enter this scope and
thus always true.
The delay values in XGI_TVDelayList2 is always 0x22 so we
can simply replace it with this constant value.

For LCD Devices:
The LCD_DelayCompensation field is always set to 0x12 so we can simply
replace this field with a constant value.

This saves about 500 bytes in compiled size.
