Subject: [PATCH 06/15] ARM: rpi: rpi3: disallow MMU_EARLY && 64BIT
Date: Thu,  5 May 2022 10:01:43 +0200	[thread overview]
Message-ID: <20220505080152.1068424-7-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220505080152.1068424-1-a.fatoum@pengutronix.de>

Early MMU setup in 64-bit Raspberry Pi 3 barebox hangs, while normal
setup concludes normally. Until this is figured out, disallow build
of 64-Bit Raspberry Pi 3 support while CONFIG_MMU_EARLY=y.

This issue doesn't affect the Raspberry Pi 4.
