smc_periph_axi_lite_xbar_pkg

Declare SMC peripheral AXI-Lite crossbar types and configuration.

Defines initiator/target counts and AXI-Lite typedefs for the peripheral CSR xbar: one 32-bit initiator, 12 targets and 14 address rules, 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_periph_axi_lite_xbar.
