From f097532d279dd7a6ab2d579425d1318051ac1f8d Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 19 Dec 2017 18:30:37 -0700 Subject: [PATCH] ARM: tegra: use CONFIG_SYS_INIT_SP_BSS_OFFSET Enable CONFIG_SYS_INIT_SP_BSS_OFFSET for all 64-bit Tegra boards. Place the stack/... 512KiB from the end of the U-Boot binary. This should be plenty to accommodate the current DTBs (max 64 KiB), early malloc region (6KiB), stack usage, and plenty of slack, while still not placing it too far away from the U-Boot binary.
