How to Modify U-boot configure for change memory size to 512M

Only need change the u-boot memsize configure.

 

     #define PHYS_SDRAM_1_SIZE                                      

                  (1u * 512 * 1024 * 1024)

Use the performance tool Antutu test system in 512M and in 1024M.

     * The statistic of Memory free after each test.

    * The improve test is reduce GPU reserve physical memory size from 192M to 128M

 

System boot-up reserve. (Static)

Use for page alloc  < 292392K

 

Browser speed

    * The Browse speed in 512M is nearly with in 1024M

 

Conclusion:

  It is acceptable for this performance when use 512M physical memory.
