I assume that you mean mem=1022M.

Quick testing results:
mem=256M works
mem=384M not
mem=524160k not (512M-128k)
mem=524228k works (512M-60k)
mem=512M works
mem=524348k not (512M+60k)
mem=524416k not (512M+128k)
mem=768M works
mem=896M not
mem=960M not
mem=1022M not
mem=1023M not
mem=1048000k not
mem=1048448k not (1024M-128k)
mem=1048514k not
mem=1048516k works (1024M-60k)
mem=1048518k works
mem=1048520k works
mem=1024M works

So I can reserve 0-60 kiB or 256 MiB but nothing between.
The device boots up with all listed values but cesa works with few
values only.

Best Regards
