smc_internal_axi_lite_xbar_pkg

Declare SMC internal AXI-Lite crossbar types and configuration.

Defines initiator/target counts and AXI-Lite typedefs for the internal CSR xbar: one initiator, 8 targets and 8 address rules on a 32-bit address and 64-bit data bus, with four outstanding transactions per port, every port cut and full connectivity. The rule type carries a 33-bit end address so a window can end at 2^32; apb_addr_rule_t is declared but unused. Address rules are defined by smc_internal_axi_lite_xbar.
