- Update SDK header files and libraries to SDK 2.0.0 plus 2.0.0_16_08_09 patch - Remove mem_manager.o from libmain.a (replaced with umm_malloc) - Disable switch from DIO to QIO mode for certain flash chips (saves IRAM space) - Add user_rf_cal_sector_set; it points to rf_init_data sector. - Change the way rf_init_data is spoofed. This is now done by wrapping spi_flash_read and returning the data we need during startup sequence. - Place lwip library into flash using linker script instead of section attributes (saves IRAM space)
