Hi Thomas, all,

Hello Maxime,
can you explain the usecase? I think, only the erase is executed per sector, all other commands are working fine with a byte oriented length.
I need to write a file that is downloaded through TFTP. So I can get the filesize through the variable of the same name, but if it's not rounded, the write command may fail. I can save the filesize in another variable, but at next boot, when I need to read this file, I can't read the file, since I only know it's size in byte, I need to be able to round it again.
Best regards, Thomas

This patch adds [+]len handler for the all the commands that will automatically round up the requested erase length to the flash's sector_size. It was previously only available for the erase command.
