Subject: [PATCH] arm: Enlarge IO_SPACE_LIMIT needed for some SoC
Date: Sun, 28 Feb 2021 15:44:04 +0100	[thread overview]
Message-ID: <20210228144405.24979-1-ansuelsmth@gmail.com> (raw)

Ipq8064 SoC requires larger IO_SPACE_LIMIT or second and third pci port
fails to register the IO addresses and connected device doesn't work.
