Documentation: at91: Update Microchip SoC documentation
We move the former Atmel wording to the the new Microchip name for this SoC family. With the name of the directory we also change the content in relation with the update of the MAINTAINERS file. The Datasheet links now point to real documents instead of 404s.

This document gives useful information about the ARM Microchip SoCs that are

currently supported in Linux Mainline (you know, the one on kernel.org).

It is important to note that the Atmel | SMART ARM-based MPU product line is
|
||||
historically named "AT91" or "at91" throughout the Linux kernel development

process even if this product prefix has completely disappeared from the

official Atmel product name. Anyway, files, directories, git trees,

It is important to note that the Microchip (previously Atmel) ARM-based MPU

product line is historically named "AT91" or "at91" throughout the Linux kernel

development process even if this product prefix has completely disappeared from

the official Microchip product name. Anyway, files, directories, git trees,
|

git branches/tags and email subject always contain this "at91" sub-string.
