| H A D | switchtec.h | a2585cdc Thu Dec 06 07:30:52 CST 2018 Paul Selles <paul.selles@microchip.com> ntb_hw_switchtec: Added support of >=4G memory windows
Current Switchtec's BAR setup registers are limited to 32bits,
corresponding to the maximum MW (memory window) size is <4G.
Increase the MW sizes with the addition of the BAR Setup Extension
Register for the upper 32bits of a 64bits MW size. This increases the MW
range to between 4K and 2^63.
