45	  BCMA bus may have many versions of PCIe core. This driver
46	  supports:
47	  1) PCIe core working in clientmode
48	  2) PCIe Gen 2 clientmode core
49
50	  In general PCIe (Gen 2) clientmode core is required on PCIe
51	  hosted buses. It's responsible for initialization and basic
52	  hardware management.
53	  This driver is also prerequisite for a hostmode PCIe core
54	  support.

81	  Some cheap devices have serial flash connected to the ChipCommon
82	  instead of independent SPI controller. It requires using a separated
