I believe you forgot to remove the 'nd' variable. Building with this patch 
(applying
patches 1 to 4 first) fails with:


../hw/riscv/microchip_pfsoc.c: In function ‘microchip_pfsoc_soc_realize’:
../hw/riscv/microchip_pfsoc.c:205:14: error: unused variable ‘nd’ 
[-Werror=unused-variable]
  205 |     NICInfo *nd;
      |              ^~
cc1: all warnings being treated as errors


Patch looks good otherwise. Thanks,

Daniel
