[PATCH 1/5] mtd: Update internal API to support 64-bit device size

[Dmitry Lavnikevich]

Hello Sascha,

eyah, I've had some problems sending mails with git send-email
through my proxy so tried to use thunderbird to pass patches outside.
Which apparently did some improvisation on them :)

Anyway, I have fixed my sendmail and will resend patches soon.

Best regards,
Lavnikevich Dmitry
