Hello. I found a discrepancy between the size of memory in the system and report by meminfo . In the following example, the system registered 512M , but the  meminfo shows only 256M. Error or so and originally intended ? barebox@i.MX51:/ devinfo mem0 resources: num   : 0 name  : ram0 start : 0x90000000 size  : 0x20000000 driver: mem bus: platform no info available for mem0 no parameters available barebox@i.MX51:/ meminfo max system bytes =     245760 system bytes     =     245760 in use bytes     =     223200 ---
