Even on 32bit systems a full 4GB of DRAM may be installed and reported by the DRAM controller. Whether these 4GB are larger available depends on the size/configuration of address decoding windows and architectural features.
This increases the fields holding the RAM size to have at least 33bits (i.e. we use a u64) and fixes the fallout from the change: some casts, the usage of min() and a few printf formats have to be adjusted.
Philipp Tomsich (9): dm: allow 4GB of DRAM on 32bit systems rockchip: support 4GB DRAM on 32bit systems common: include <inttypes.h> always MIPS: use PRIx64 macros for printing ram size rockchip: rk3368: change type of ram-size field for a min()-calculation ram: stm32mp1: use PRIx64 macros for printing ram size board: keymile: add explicit cast to truncate the 64bit ram size field board: cm_fx6: use PRIx64 macros for printing ram size mpc85xx: add casts for ram size in min() calculation.
