Reserved
GbE Master Write Access Grant (GMWAG): — R/WL. Each bit [27:25] corresponds
to Master[3:1]. GbE can grant one or more masters write access to the GbE region 3
overriding the permissions in the Flash Descriptor.
Master[1] is Host CPU/BIOS, Master[2] is ME, Master[3] is Host CPU/GbE.
The contents of this register are locked by the FLOCKDN bit.
Reserved
GbE Master Read Access Grant (GMRAG): — R/WL. Each bit [19:17] corresponds to
Master[3:1]. GbE can grant one or more masters read access to the GbE region 3
overriding the read permissions in the Flash Descriptor.
Master[1] is Host CPU/BIOS, Master[2] is ME, Master[3] is GbE.
The contents of this register are locked by the FLOCKDN bit.
Reserved
GbE Region Write Access (GRWA): — RO. Each bit [11:8] corresponds to Regions
[3:0]. If the bit is set, this master can erase and write that particular region through
register accesses.
The contents of this register are that of the Flash Descriptor. Flash Master 3.Master
Region Write Access OR a particular master has granted GbE write permissions in their
Master Write Access Grant register OR the Flash Descriptor Security Override strap is
set.
Reserved
GbE Region Read Access (GRRA): — RO. Each bit [3:0] corresponds to Regions
[3:0]. If the bit is set, this master can read that particular region through register
accesses.
The contents of this register are that of the Flash Descriptor. Flash Master 3.Master
Region Write Access OR a particular master has granted GbE read permissions in their
Master Read Access Grant register.
