From 7f80deb0c6c779ee19996918962c8cad058efd10 Mon Sep 17 00:00:00 2001 From: Vaishnav Achath Date: Sat, 13 May 2023 19:47:09 +0530 Subject: [PATCH] arm64: dts: ti: k3-j7200-som: Describe OSPI and Hyperflash partition info Describe OSPI and Hyperflash partition information through device tree, this helps to remove passing partition information through the mtdparts commandline parameter which requires maintaining the partition information in a string format. J7200 SoM has a S28 64 MiB OSPI flash with sector size of 256 KiB thus the size of the smallest partition is chosen as 256 KiB, the SoM also has a 64 MiB Hyperflash present on it, the partition names and offsets are chosen according to the corresponding name and offsets in bootloader.
