From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Wed, 25 Sep 2019 08:56:30 -0600 Subject: [U-Boot] [PATCH 046/126] spl: Allow distinguishing between two phases in U-Boot In-Reply-To: <20190925145750.200592-1-sjg@chromium.org> References: <20190925145750.200592-1-sjg@chromium.org> Message-ID: <20190925145750.200592-47-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 U-Boot has two distinct phases: before and after relocation. These are commonly referred to as F (running from Flash) and R (Relocated and running from RAM). Some drivers want to do different things in these phases so update the SPL phase function to return a different value for each.
