I want to change sdram size, but i can't find the option. The kernel version is 22.214.171.124. please tell me how to config. However, In 126.96.36.199，options CONFIG_MEM_SIZE and CONFIG_MEM_ADD_WIDTH can do it. thanks!
For a new board with different memory, this can be achieved by modifying the in u-boot board configuration file, for example include/configs/bf548-ezkit.h.
In 188.8.131.52, Not only do we modify uboot, but also modify kernel option. If only modify uboot, it can run properly in new version?
I think so, the reg settings in u-boot will be retained when Linux is up.
