Subject: [U-Boot] [PATCH 0/9] Support 4GB of memory on 32bit systems
Date: Thu, 26 Jul 2018 15:59:42 +0200	[thread overview]
Message-ID: <1532613591-8444-1-git-send-email-philipp.tomsich@theobroma-systems.com> (raw)


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.
