libfdt: Fix undefined behaviour in fdt_offset_ptr()

Using pointer arithmetic to generate a pointer outside a known object is,
technically, undefined behaviour in C.  Unfortunately, we were using that
in fdt_offset_ptr() to detect overflows.

To fix this we need to do our bounds / overflow checking on the offsets
before constructing pointers from them.

8 years agocmd/fdt: add possibilty to have 'extrasize' on fdt resize
Hannes Schmelzer [Tue, 20 Sep 2016 16:10:43 +0000 (18:10 +0200)]
cmd/fdt: add possibilty to have 'extrasize' on fdt resize

Sometimes devicetree nodes and or properties are added out of the u-boot
console, maybe through some script or manual interaction.

The devicetree as loaded or embedded is quite small, so the devicetree
has to be resized to take up those new nodes/properties.

In original the devicetree was only extended by effective
4 * add_mem_rsv.

With this commit we can add an argument to the "fdt resize" command,
which takes the extrasize to be added.

ARM: tegra: reduce DRAM size mapped into MMU on ARM64

ARM CPUs can architecturally (speculatively) prefetch completely arbitrary

current MMU configuration for 64-bit Tegras maps an extremely large range

even though U-Boot only needs access to the first 2GB of DRAM; the Tegra

modules on at least some 64-bit Tegra SoCs can only access a 32-bit
physical address space. This change reduces the amount of RAM mapped via
the MMU to disallow the CPU from ever speculatively accessing RAM that
U-Boot will definitely not access. This avoids the possibility of the HW
