This option was only providing a 64MB boot time memory

of memory on the devices with only 512MB of RAM (such
as A10-OLinuXino-LIME).
Moreover, the "sunxi_no_mali_mem_reserve" kernel cmdline
option (implemented as part of this code) was unsafe and
allowed the unsuspecting users to cause memory corruption
and take down the system by just modprobing the mali kernel
module.
Because the Mali400 GPU has MMU, it does not strictly need
boot time memory reservation and can work just fine with
just dynamic memory allocation. There have been no evidences
presented in favour of keeping this boot time memory
reservation. Also the Mali400 MP2 GPU on sun7i hardware
does not currently use this boot time memory reservation
at all.
