 {{{
 We are talking about choosing some options from the full list:

 * chip read
 * chip erase
   chip write (0xff to other)
 * chip erase-and-write (option 'write')

   partial read
   partial erase
 1 partial write
 2 partial erase-and-write

 * = Options we have
 1 = Carl-Daniel suggests
 2 = Other people suggest

 Every option in the list is useful in some case. My opinion on -

 the choice  - Support the full list;
 1           - Warning and ask for continuation. No checking for 0xff;
 2           - We need this convenience for partial modification.

 My two cents.
