[ptxdist] [PATCH] at91bootstrap2: Add license information

[ptxdist] [PATCH] at91bootstrap2: Add license information

[Alexander Dahl via ptxdist]

Up to the last v3 release v3.10.4 from 2021 there is no global licensing
statement in the source tree, but almost all files have a header
matching the 'BSD-Source-Code' license (as with v1 and probably v2
already).

For v4.0.0-rc4 Microchip (after buying Atmel) re-licensed the whole
source tree to 'MIT' license.

Notes:
    FatFs license was considered, but left out for the following reasons:
    
    If CONFIG_SDCARD is set, an older copy of FatFs is part of the build.
    That source has a custom license which only requires mentioning if
    redistributed as source, thus it's not added to the list of licenses
    here.  (Otherwise to my understanding it would have to be always
    included regardless if it's actually built e.g. also for systems without
    SD/eMMC.  Or some complicated mechanism needs to be added to the make
    rule parsing that actual configuration, and adding the license
    conditionally.)
    
    / FatFs module is a generic FAT file system module for small embedded systems.
    / This is a free software that opened for education, research and commercial
    / developments under license policy of following terms.
    /
    /  Copyright (C) 2011, ChaN, all right reserved.
    /
    / * The FatFs module is a free software and there is NO WARRANTY.
    / * No restriction on use. You can use, modify and redistribute it for
    /   personal, non-profit or commercial products UNDER YOUR RESPONSIBILITY.
    / * Redistributions of source code must retain the above copyright notice.
    
    The authors website has some more explanation: "In order to extend the
    usability for commercial products, the redistributions of FatFs in
    binary form, such as embedded code, binary library and any forms without
    source code, does not need to include about FatFs in the
    documentations."
