From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Mon, 1 Oct 2018 12:22:15 -0600 Subject: [U-Boot] [PATCH 11/45] rtc: Allow use of RTC in SPL and TPL In-Reply-To: <20181001182249.129565-1-sjg@chromium.org> References: <20181001182249.129565-1-sjg@chromium.org> Message-ID: <20181001182249.129565-12-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add Kconfig options so that the RTC can be used in SPL and TPL. This is helpful for accessing the contents of CMOS RAM, for example.
