PS83, Line 37: int erase_write(struct flashctx *const flashctx, chipoff_t region_start, chipoff_t region_end, uint8_t* curcontents, uint8_t* newcontents, struct erase_layout *erase_layout, bool *all_skipped);
> Done

But it still looks the same in the latest patchset? :)

I see you added file to build system, because now jenkins builds it, good!

Also jenkins build has an error, you can see it by:
clicking the link which jenkins gives you with -1
clicking Console Output on the left menu
scroll to the end of console output, it tells
```
erasure_layout.c: In function 'erase_write':
erasure_layout.c:399:9: error: 'old_end_buf' may be used uninitialized [-Werror=maybe-uninitialized]
