config SOC_AMD_COMMON_BLOCK_DATA_FABRIC
bool
help
Select this option to add data fabric configuration related
functionality to the build.
config SOC_AMD_COMMON_BLOCK_DATA_FABRIC_DOMAIN
bool
depends on SOC_AMD_COMMON_BLOCK_DATA_FABRIC
select SOC_AMD_COMMON_BLOCK_ROOT_COMPLEX
help
Select this option to add functionality to the build to tell the
resource allocator about the MMIO regions configured in the data
fabric registers so that it knows in which regions it can properly
allocate the non-fixed MMIO devices.
config SOC_AMD_COMMON_BLOCK_DATA_FABRIC_MULTI_PCI_SEGMENT
bool
depends on SOC_AMD_COMMON_BLOCK_DATA_FABRIC_DOMAIN
help
Some AMD SoCs support more than one PCI segment with 256 buses. Those
SoCs however have a different data fabric register layout for the PCI
bus number decoding. SoCs that use a data fabric register pair for
the PCI bus number which includes the segment number must select this
option; SoCs that use one data fabric register for the PCI bus number
which doesn't include a segment number field mustn't select this.
config SOC_AMD_COMMON_BLOCK_DATA_FABRIC_EXTENDED_MMIO
bool
depends on SOC_AMD_COMMON_BLOCK_DATA_FABRIC_DOMAIN
help
Some AMD SoCs support more than 48 bit MMIO addresses. In order to
have enough bits for this, the MMIO address extension register is
introduced. SoCs that have this register must select this option in
order for the MMIO regions to be reported correctly.
