From cff451e03ff3c9612723c8ab2b8b5be525538936 Mon Sep 17 00:00:00 2001 From: Teresa Remmet Date: Tue, 28 May 2024 15:35:13 +0200 Subject: board: phytec: phycore_imx8mp: Add support for different RAM sizes Add support for different RAM sizes and speed grades on the phyCORE-i.MX8MP. Add support for 1GB 1.5GHz, 1GB 2GHz, 4GB 1.5GHz, 4GB 2GHz and 8GB 2GHz RAM. The RAM size and speed grade is detected by the information stored in the EEPROM on the SoM.
