What I still dislike about target_phys_addr_t is that "ram_size" is not an address but a size. Andreas

But isn't MAX(size) always defined to be smaller than or equal to MAX(addr)? So target_phys_addr_t is _always_ a type that is big enough to hold the information. Alex

So target_phys_addr_t is _always_ a type that is big enough to hold the information. I'm not disputing that. If you do typedef target_phys_addr_t/* or whatever */ target_phys_size_t; target_phys_size_t ram_size; then I'm happy as well, I just dislike writing target_phys_addr_t size. Andreas

Make the RAM size in arm_boot_info a target_phys_addr_t so it can express RAM sizes up to the limit imposed by the physical address size. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- hw/arm-misc.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
