2017-11-02Mark or fix switch cases that fall throughDavid Oberhollenzer
Now that C++17 introduced a special fallthrough keyword for explicitly tagging switch cases that are supposed to fall through, newer gcc versions also implement a feature request from 2002 to warn about maybe unwanted fall-throughs in switch cases in other languages (like C). For C code, we can either add a gcc specific attribute at the end of the switch case, or use a special comment that gcc checks for, indicating that the fall-through behaviour is indeed intended. This patch adds a "/* fall-through */" comment at the end of various case blocks to silence gcc warnings and in some cases a break, where fall-through was probably not intended.

2017-01-18nanddump: Add --skip-bad-blocks-to-start optionMike Crowe
The --skip-bad-blocks-to-start option will increase the start address by the size of each bad block encountered between the start of the partition and the specified start address. This can be useful if other readers of the partition will be reading using a simple bad-block-skipping algorithm.

2016-11-17Unify version string printingDavid Oberhollenzer
When a program does sophisticated enough command line processing (i.e. getopt), make sure it responds to -V and --version. When a program prints a version string, make sure it uses the common_print_version macro to print out its name, that it is part of mtd-utils and the mtd-utils version from the build system in a fashion similar to common program packages like the GNU coreutils. When a program responds to -V/--version or -h/--help, make sure it reports success exit status.

2016-11-17nanddump: check write function result for errorsRafał Miłecki
Errors may happen, it's e.g. easy on embedded devices to run out of space when dumping big partitions. This patch adds a helper function for writing. It deals with partial writes and just returns 0 on success or error number. The old code didn't check for errors at all which could result in incomplete dumps without exiting with an error.

2016-08-25mtd-utils: nanddump: write requested length onlyGary Bisson
nanddump was always writing a whole page of data into the output discarding the length actually requested. This patch allows to write only the remaining length if oob is omitted. In case oob is needed, it makes sense to copy the entire page. Signed-off-by: Richard Weinberger <richard@nod.at>
2015-11-11mtd-utils: Restructure the mtd-utils source.Dongsheng Yang
* There is no code modification in this commit, only moving * the files to proper place. The user tools looks a little messy as we place almost the all tools in the root directory of mtd-utils. To make it more clear, I propose to introduce the following structure for our source code. mtd-utils/ |-- lib |-- include |-- misc-utils |-- jffsX-utils |-- nand-utils |-- nor-utils |-- ubi-utils |-- ubifs-utils `-- tests Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
