Reorganize the and optimize the code to avoid redundant code and thus reduce code size, while making sure to zero-initialize the used areas on the SD card. These are the "clean" part of this change. The "dirty" part: Optimize the FAT16 export code further by introducing small deviations from the FAT16 specification. These deviations should not be harmful at all, unless the SD card is used for something requiring the jump instruction and/or boot code in the boot sector to be valid. This is typically only required when booting off the filesystem. After these changes, a considerable reduction in code size can be observed for sys_controller.elf and sys_onchip_memory2_0.bin: sys_controller.elf: text data bss dec hex filename 32392 2936 2652 37980 945c sys_controller.elf sys_onchip_memory2_0.bin: size: 35328 bytes This reduces the cost of the FAT16 export feature to 446 bytes. |
