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).
