PS1, Line 8: 
           : This was missed because `uint32_t` is `unsigned int` in most cases.
           : However, it is not the case for DJGPP 6.1.0 for some reason.
this does not sit right with me. I believe the correct fix here is to simply correct the prototypes in chipdrivers.h which seem to be wrong:

```
git grep -E '(s25fs_block_erase_d8|s25fl_block_erase)' chipdrivers.h
chipdrivers.h:int s25fl_block_erase(struct flashctx *flash, unsigned int addr, unsigned int blocklen);
chipdrivers.h:int s25fs_block_erase_d8(struct flashctx *flash, unsigned int addr, unsigned int blocklen);
```

uint32_t seems to be the correct type.
