Subject: [PATCH v2 13/21] ARM: rpi: add Raspberry Pi 3 64-bit build support
Date: Thu, 9 Jun 2022 07:59:14 +0200 [thread overview]
Message-ID: <20220609055922.667016-14-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220609055922.667016-1-a.fatoum@pengutronix.de>
Have the subarch select the needed symbols to display a 32-bit/64-bit
menu and hide the boards that aren't capable of 64-bit when
CONFIG_64BIT=y. Building for 64-bit throws some warning about mismatched
type sizes, so fix those as well.
