From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michal Simek Date: Mon, 16 Nov 2020 16:02:19 +0100 Subject: [PATCH v2 6/6] microblaze: Detect NOR flash based on DT In-Reply-To: References: Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Remove fixed configuration and detect flash based on DT. Also increase amount of flash sectors to 2048 because on kc705 flash has 1027 sectors.
