Adjust RAM

SSD201 has 64MB of memory, part of which is used for MMA providing for some modules such as VDEC, VENC,etc. Another part is used for Linux system, and a small part (1M) is used for AI, AO and wireless. Therefore, after the Linux system is on, use the command Free to find that the total amount of memory is less than 128M, because a considerable part is used for MMA.

# Take WT2012 as an example, modify the value of sz in ssd20x-images-open/WT2012/scripts/set_config to resize MMA memory
sz=0x1a0000

If only 1080P hard decoding is required, MMA should be allocated about 9MB, and it is recommended not to be less than 4MB.
