+Subject: [PATCH 5/5] Updated SCU88 register and SCU90 init values
+
+From:    Adi Gangidi <adi.gangidi@rackspace.com>
+
+Before This change:
+a) SCU90[0]=1, function pin Incorrectly defined. It must be pull down internally.
+b) For SCU88, bits 7:0 were set to 1. That is: We were reading : PWMx or VPIGx instead of GPIONx (GPIONx gives us the PCIe inventory status, where x is bit number). Because of this PCIe inventory was showing up wrong.
+
+After This Change:
+a) SCU90[0]=0
+b) Bits (7:0) of SCU 88 are set to 0 . (According to Page 111 of data sheet these have to be set to 0 for us to to read GPION0 to GPIO N7 which indicate if PCIe device is present ).
+
+Description of pins 0 of SCU 90:
+Enable SD1 Function Pin
+
+Description of pins 7:0 of SCU 88:
+7 RW Enable PWM7 or VPIG7 function pin  (SCU90[5:4]=0x2 select Video pin)
+6 RW Enable PWM6 or VPIG6 function pin   (SCU90[5:4]=0x2 select Video pin)
+5 RW Enable PWM5 or VPIG5 function pin    (SCU90[5:4]!=0 select Video pin)
+4 RW Enable PWM4 or VPIG4 function pin     (SCU90[5:4]!=0 select Video pin)
+3 RW Enable PWM3 or VPIG3 function pin      (SCU90[5:4]!=0 select Video pin)
+2 RW Enable PWM2 or VPIG2 function pin        (SCU90[5:4]!=0 select Video pin)
+1 RW Enable PWM1 or VPIG1 function pin        (SCU90[5:4]=0x3 select Video pin)
+0 RW Enable PWM0 or VPIG0 function pin         (SCU90[5:4]=0x3 select Video pin)
