From: Michal Simek Date: Mon, 4 May 2020 11:54:40 +0000 (+0200) Subject: cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=e519f03a18464c1fe249bd7fcf7829fad31abc9a;p=u-boot.git cmd: mem: Remove CONFIG_SYS_MEMTEST_SCRATCH mapping There is no real need to exactly define space for saving patterns for alternate memory test. It is much easier to allocate space on the stack and use it instead of trying to find out space where pattern should be saved. For example if you want to test the whole DDR memory you can't save patter to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses were chosen but that means that OCM needs to be mapped and U-Boot has access permission there. It is easier to remove this limitation and simply save it on stack because it is very clear that memory test can't rewrite U-Boot and U-Boot has also full access to memory where runs from.
