Kinetis SDK examples - Design Patterns

Hi,

I'm curious to know about the design pattern used in the Kinetis SDK examples so that I can customize the code easily. For example in the bootloader code, all the interfaces defined by structures, implementations are mapped in various .c files (memory.c, bl_tree_root.c, property_kinetis.c) and then called in bl_main.c
Where can I find more information about design patterns used in Kinetis SDK examples and any best practices for NXP Kinetis MCUs?

example -

In bl_context.c

bootloader_context_t g_bootloaderContext = {.memoryInterface = &g_memoryInterface, .memoryMap = g_memoryMap, #if BL_FEATURE_EXPAND_MEMORY .externalMemoryMap = g_externalMemoryMap, #endif // BL_FEATURE_EXPAND_MEMORY .allPeripherals = g_peripherals, .activePeripheral = NULL, // Filled in at run time. .propertyInterface = &g_propertyInterface, .commandInterface = &g_commandInterface, #if !BL_FEATURE_HAS_NO_INTERNAL_FLASH .flashDriverInterface = &g_flashDriverInterface, #if !BL_DEVICE_IS_LPC_SERIES .allFlashState = &g_flashState, .allFlashCacheState = &g_flashcacheState, #if BL_FEATURE_SUPPORT_DFLASH .dflashDriverInterface = &g_dflashDriverInterface, .dFlashState = &g_dflashState, #endif // BL_FEATURE_SUPPORT_DFLASH #else .allFlashState = g_flashState, #endif // !BL_DEVICE_IS_LPC_SERIES #endif // #if !BL_FEATURE_HAS_NO_INTERNAL_FLASH #if AES_SECURITY_SUPPORTED .aesInterface = &g_aesInterface, #endif };

In bl_main.c

// Init the active peripheral. if (g_bootloaderContext.activePeripheral->byteInterface && g_bootloaderContext.activePeripheral->byteInterface->init) { g_bootloaderContext.activePeripheral->byteInterface->init(g_bootloaderContext.activePeripheral); } if (g_bootloaderContext.activePeripheral->packetInterface && g_bootloaderContext.activePeripheral->packetInterface->init) { g_bootloaderContext.activePeripheral->packetInterface->init(g_bootloaderContext.activePeripheral); }

Thank you in advance.
