From 879c9fc4210fa508fdc7e23e6a53709d5751d513 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Fri, 1 Nov 2019 21:42:33 +0100 Subject: soc/nvidia/tegra210: Populate _cbmem_top_ptr On this platform the ramstage is run on a different core so passing cbmem_top via calling arguments is not an option. To work around this populate _cbmem_top_ptr with cbmem_top_chipset which is also used in romstage.
