We are planning to have a common u-boot for 2 different hardware with different DDR size. One hardware with 2 GB DDR and other with 512 MB DDR. We are using iMX6 Dual core custom boards.


Is it possible to have a common u-boot with some default DDR configuration so that it will work for 2 boards ?

After booting with default DDR configuration, reconfigure DDR based on the actual DDR size from u-boot .


The DDR sizes of two boards are as follows


1) 64x16 MB ( 4 DDR )  - 512 MB. 

2) 512x16 MB (4 DDR)  - 2 GB.


The plan was to boot with mnimum DDR size ( 512) and after boot up read hardware BOM to identify the actual DDR size need to be configured . If the size is not matching reconfigure DDR from u-boot itself.


Is it really possible ??
