Request to review Lint Issues in Veer RTL

[amullick007]

Hi, I am filling this issue to review couple of Lint issues inside Veer RTL.

1. In el2_veer.sv file, below highlighted signals are read but never set.

   assign ifu_axi_bready_int = pt.BUILD_AHB_LITE ? ifu_axi_bready_ahb : ifu_axi_bready;
   assign lsu_axi_bready_int = pt.BUILD_AHB_LITE ? lsu_axi_bready_ahb : lsu_axi_bready;
   assign sb_axi_bready_int = pt.BUILD_AHB_LITE ? sb_axi_bready_ahb : sb_axi_bready;

2. Output signal highlighted below is never set.

Output 'ifu_bp_fa_index_f' is never set. (veer_el2/rtl/ifu/el2_ifu_bp_ctl.sv)
