From 72a1b9a977e8636b9c364f2cbf21371afe143c68 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Wed, 28 Oct 2020 11:58:16 +0200 Subject: [PATCH] verdin-imx8mm: automatic ram size detection Implement board_phys_sdram_size() to automatically detect Verdin iMX8M Mini DualLite 1GB vs. Verdin iMX8M Mini Quad 2GB. Note: This only works if we keep using similar RAM chips!
