<Abstract>Component description file for IsaBus module.</Abstract>
<Description>Discovers all the ISA Controllers and their resources by using the ISA PnP
Protocol, produces an instance of the ISA I/O Protocol for every ISA
Controller found, loads and initializes all ISA Device Drivers, matches ISA
Device Drivers with their respective ISA Controllers in a deterministic
manner, and informs a ISA Device Driver when it is to start managing an ISA
Controller.</Description>

<HelpText>This feature flag is used to enable the implementation for interface
_EFI_ISA_IO_PROTOCOL.Mem.Read, _EFI_ISA_IO_PROTOCOL.Mem.Write and _EFI_ISA_IO_PROTOCOL.CopyMem.
If it is unset, these interfaces will return EFI_UNSUPPORTED. When it is disabled,
it is will save code size if a platform does not have ISA device with ISA memory.</HelpText>

<HelpText>This feature flag is used to enable the implementation for interface
_EFI_ISA_IO_PROTOCOL.AllocateBuffer, _EFI_ISA_IO_PROTOCOL.FreeBuffer, _EFI_ISA_IO_PROTOCOL.Map
and _EFI_ISA_IO_PROTOCOL.UnMap. If it is unset, these interfaces will return EFI_UNSUPPORTED.

<C_Name>PcdIsaBusOnlySupportSlaveDma</C_Name>
<TokenSpaceGuidCName>gEfiGenericPlatformTokenSpaceGuid</TokenSpaceGuidCName>
<DefaultValue>FALSE</DefaultValue>
<HelpText>This feature flag is used to enable the implementation for interface
_EFI_ISA_IO_PROTOCOL.Map and _EFI_ISA_IO_PROTOCOL.UnMap to only support Slave DMA
transfers. In addition, unsetting this feature flag also make AllocateBuffer() and
FreeBuffer() to return EFI_UNSUPPORTED. It is useful to save code size if a platform have only
ISA device to do slave DMA R/W transfer. This flag is only effective when PcdIsaBusSupportDma
is set to TRUE. If PcdIsaBusSupportDma is set to FALSE, Map() and UnMap() will simply
return EFI_UNSUPPORTED. Please check description for PcdIsaBusSupportDma for details.</HelpText>
