Questions about OTP driver

[Stefan Wahren]

Hi,

currently i try to port a driver for One Time Programmable memory pages on
Freescale MX23/MX28 (ARM9) SoC.
This driver gives readonly access to these memory pages via Sysfs.

As i created a patch RFC [1], Arnd Bergmann suggested me to move the driver to
MTD.

Now i have some questions:

1. What exact directory is suggested for OTP on SoC driver?
2. What is a good example implementaton of an OTP driver?

Best regards

Stefan Wahren
