Subject: [PATCH 12/12] lmb: x86: Add arch_lmb_reserve()
Date: Fri, 10 Sep 2021 22:47:18 +0200	[thread overview]
Message-ID: <20210910204718.17765-12-marek.vasut+renesas@gmail.com> (raw)
In-Reply-To: <20210910204718.17765-1-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.
