> New in v2:
> 
>  * Change wording: use byte for 8-bits chunks and addressable memory unit
>    for the unit of data associated to a single address.
>  * Introduce definition of addressable memory unit in the Memory
>    section.
> 
> This patch modifies the manual to clarify the MI, RSP and Python APIs in
> regard to reading/writing memory on architectures with addressable
> memory unit that are not 8 bits.
> 
> Care is taken to use the word "addressable memory unit" or "memory unit"
> when referring to one piece of the smallest addressable size on the
> current architecture and the word "byte" when referring to an 8-bits
> data piece.

This patch is fine with me, thanks.
