Subject: [PATCH v2 11/13] MIPS: jz4740: Drop folder
Date:   Wed, 12 Aug 2020 02:15:08 +0200
Message-Id: <20200812001510.460382-12-paul@crapouillou.net>
In-Reply-To: <20200812001510.460382-1-paul@crapouillou.net>

Precedence: bulk

Support for Ingenic SoCs is now provided by the arch/mips/generic/ code,
so the arch/mips/jz4740/ folder can be completely dropped. The exception
is the Kconfig, which has been moved to arch/mips/ingenic/Kconfig in the
process.
