Subject: [PATCH 11/14] lmb: xtensa: Add arch_lmb_reserve()
Date: Sun, 15 Aug 2021 20:13:11 +0200	[thread overview]
Message-ID: <20210815181314.132330-11-marek.vasut+renesas@gmail.com> (raw)
In-Reply-To: <20210815181314.132330-1-marek.vasut+renesas@gmail.com>

Add arch_lmb_reserve() implemented using arch_lmb_reserve_generic().
It is rather likely this architecture also needs to cover U-Boot with
LMB before booting Linux.
