Subject: [Buildroot] [PATCH v3] board: Add support for terasic DE10 Nano
Date: Wed, 21 Jul 2021 14:59:08 +0200	[thread overview]
Message-ID: <1626872348-69423-1-git-send-email-gwenj@trabucayre.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 7228 bytes --]

From: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com>

Terasic DE10 Nano is an SoCFPGA cycloneV based board.
References:
- https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=205&No=1046
- https://rocketboards.org/foswiki/Documentation/DE10NanoDevelopmentBoard

Note: there is no dts in kernel (mainline or intel), but since DE0 Nano Soc is
similar, the corresponding dts is usually used
