Seems it parameter are ignored. In my 'syslog' reserved memory size not depends on it, all time 256M
cma: CMA: reserved 256MiB at 50000000
I guess, that ION memory manager set 256M reserving... Also i tried rebuild image with:
CONFIG_ION_SUNXI_RESERVE_LIST="256M@0,384M@0,130M@1,200M@1"
Unfortunately, still same behavior.
