2023-08-24	Fix printf format specifiers for 64 bit integer types	David Oberhollenzer
	In nandflipbits, nandtest and ubiscan, uint64_t integers are printed to stdout using "%llu" as a format specifier, but on platforms like x86_64, uint64_t is actually typedef'd as `unsigned long` only. For compatibillity across platforms, simply use the C99 printfs macros instead. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-09-06	Add ubiscan utility	Diego Ismirlian
	ubiscan will scan the PEBs in a specific MTD device and print a summary of the PEB erase counters and (optionally) details about each PEB's status. Example output: # ./ubiscan /dev/mtd6 Summary ========================================================= mtd : 6 type : nand size : 110362624 bytes (105.2 MiB) PEBs : 842 min I/O: 2048 bytes PEB erase counters ========================================================= valid : 834 empty : 0 corrupted: 0 alien : 0 bad : 8 Histogram ========================================================= from to count min avg max --------------------------------------------------------- 0 .. 9: 55 1 4 9 10 .. 99: 174 10 48 99 100 .. 999: 514 103 287 987 1000 .. 9999: 91 1004 1880 2251 10000 .. 99999: 0 0 0 0 100000 .. inf: 0 0 0 0 --------------------------------------------------------- Total : 834 1 392 2251 If the --verbose switch is given, ubiscan will print PEB details: # ./ubiscan --verbose /dev/mtd6 [... same output as before ...] Details ========================================================= PEB 0: 253 PEB 1: 1489 PEB 2: 1 PEB 3: 1 PEB 4: 1 PEB 5: 1 PEB 6: 1 PEB 7: 1 PEB 8: 1 PEB 9: 1 PEB 10: 1 ...
