* common: Add get_effective_memsize() to memsize.cYork Sun2014-02-211-1/+15
| | | | | | | | | This function has been around for powerpc. It is used for systems with memory more than CONFIG_MAX_MEM_MAPPED. In case of non-contiguous memory, this feature can limit U-boot to one block without going over the limit.

* Revert "memsize: Fix for bug in memory sizing code"Tom Rini2012-09-211-1/+0
| | | | | | | | | | After further investigation this change is not correct and results in get_ram_size returning incorrectly large values. Reported first by Gerlando Falauto. This reverts commit b8496cced856ff411f1eb2e4eff20f5abe7080b0. Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | The original memory sizing code in get_ram_size clobbers the word at the base address, but forgets to restore it. Signed-off-by: Iwo Mergler <Iwo.Mergler@netcommwireless.com>
* Remove volatile qualifier in get_ram_size() callsAlbert ARIBAUD2011-07-171-1/+1
| | | | | | | | | Checkpatch.pl complains about the volatile qualifier in calls to get_ram_size(). Remove this qualifier in the prototype and in the calls where it is useless, and leave it only in the function body where it is needed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
