Generated Registers space smaller than the defined address range

[DerekWangScaleflux]

Hi Caliptra team,
There is a potential issue in the current generated registers module: the address range of generated register module is smaller than the defined address range.

    For example, DOE space range is defined as 0x1000_0000 to 0x1000_7FFF, address width is 15 bits.
    But generated DOE register module only use address bit [11:0].

    So if CPU is accessing address 0x1000_1000, it is accessed the reserved space of DOE registers, but actually it will corrupt the register 0x1000_0000.

     This will be a potential issue, right ? Because software could go wrong somewhere, and it will be hard to debug if software write some reserved register address.

     Pls help to comment.

Best Regards
Derek Wang
