    116116The Yocto and Android BSP's have a bootscript that among other things comes up with a default cma allocation by looking at the total board memory available. If you find you need to alter this number (ie you do not want 'any' allocated) you can set the mem bootloader paramater to disable the auto-configuration performed by the bootscript.

     118To force a certain amount of CMA on Ventana, use the following command in the bootloader, adjusting the value (eg 96M) as needed:
     119{{{
     120setenv mem 'cma=96M'
     121}}}
     122
