There is currently a hardcoded limit of 64KB for the DTB to live in and be extended with ATAG info. Some DTBs have outgrown that limit: $ du -b arch/arm/boot/dts/omap3-n900.dtb 70212 arch/arm/boot/dts/omap3-n900.dtb Furthermore, the actual size passed to atags_to_fdt() included the stack size which is obviously wrong. The initial DTB size is known, so use it to size the allocated workspace with a 50% growth assumption and relocate the temporary stack above that. This is also clamped to 32KB min / 1MB max for robustness against bad DTB data.
