Squashed commit of the following:

Browse Source 
Silence lint on intentional combinatinal loops
    Use better instance names, and a single lint pragma for all macros
    Remove unused pointer update signals
    Silence lint on wires where not all bits are used
    Change fw_app_mode to be an input port to allow access control
    Remove redundant, unused wire mem_busy
    Add lint pragma to ignore debug register only enabled by a define
    Remove clk and reset_n ports from the ROM
    Adding note and lint pragma for rom address width
    Fix incorrect register widths in uart_core
    Assign all 16 bits in LUT config
    Silence lint warnings on macro instances
    Correct bit extraction for core addresses to be eight bits wide
    Correct the bit width of cdi_mem_we wire
    Add specific output file for logging lint issues
    Correct bit width of tmp_ready to match one bit ready port
