From: Jonathan Hunter Date: Tue, 12 Feb 2019 16:03:14 +0000 (+0000) Subject: ARM: tegra: Reserve 32MB for the Linux kernel X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f16e3115f3b601f121798070b97224b8234d71b7;p=project%2Fbcm63xx%2Fu-boot.git ARM: tegra: Reserve 32MB for the Linux kernel Booting recently Linux -next kernels on 32-bit Tegra devices has been failing when using the 'multi_v7_defconfig' kenrel configuration because the size of has grown such that it is overwriting the FDT blob. Current Linux -next kernels built with the 'multi_v7_defconfig' have a total size of ~19.5MB (where .text is ~12.5MB, .data is ~6.5MB and .bss is ~0.5MB). Therefore, increase the memory location reserved for the Linux kernel to 32MB from 16MB for 32-bit Tegra devices. This change has been boot tested on Tegra20 Ventana, Tegra30 Cardhu and Tegra124 Jetson TK1 with the Linux next tree (20190212).
