[Buildroot] [PATCH v3 1/2] boot/at91bootstrap3: add support for at91bootstrap 4.x series

[Eugen Hristev]

Introduce support for the next generation of at91bootstrap,
at91bootstrap 4.x series.

AT91Bootstrap 4.x only supports devices: sam9x60, sama5d2, sama5d3,
sama5d4, sama7g5.

User can select 4.x series as a bool, and if so, the latest 4.x
version is automatically selected.
If the user deselects this option, only 3.x latest version can be
picked.
