Subject: [PATCH master 3/6] clocksource: armv7m_systick: fix MMIO address
Date: Mon, 12 Jun 2023 14:53:28 +0200 [thread overview]
Message-ID: <20230612125331.1085059-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230612125331.1085059-1-a.fatoum@pengutronix.de>
SYST_CALIB is a register within the ARMv7-M SysTick peripheral, but we
erroneously dereferenced some random spot within the barebox data
section. Fix this.
