2009-06-12General help message cleanupWolfgang Denk
Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-06-12cmd_mtdparts.c: allow to omit definitions for default settingsWolfgang Denk
There is actually no good reason to enforce that all board configuations must define default settings for "mtdids" and "mtdparts". Actually this may be difficult to handle, especially on boards where different sizes of flash chips can be fit, so there is no real "default" partition map for all boards. Lift this arbitrary limitation. Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-06-12cmd_mtdparts: Move to common handling of FLASH devices via MTD layerStefan Roese
This patch removes all references to the direct CFI FLASH interface (via flash_info[]). Now that all FLASH types currently handled in mtdparts are available (if selected, see below) via the MTD infrastructure. This is NOR, NAND and OneNAND right now. This can be achieved by defining the following options: CONFIG_MTD_DEVICE (for all FLASH types) plus CONFIG_FLASH_CFI_MTD (for NOR FLASH) So we need to add those defines to the board config headers currently using the mtdparts commands. This is done via another patch, so we shouldn't break mtdparts compatibility. One big advantage from this solution is that the cmd_mtdparts.c is *much* cleaner now. Lot's of #ifdef's are removed and the code itself is smaller. Additionally the newly added MDT concatenation feature can new be used via the mtdparts infrastructure and therefor via UBI etc. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Ladislav Michl <ladis@linux-mips.org> Cc: Scott Wood <scottwood@freescale.com>
2009-05-28jffs2/mtdparts: Fix problem with usage from JFFS2 and MTDPARTS togetherStefan Roese
Currently using JFFS2 with MTDPARTS enabled doesn't work. This is because mtdparts_init() is available in both files, cmd_mtdparts.c and cmd_jffs2.c. Please note that in the original cmd_jffs2.c file (before the jffs2/mtdparts command/file split those 2 different versions already existed. So this is nothing new. The main problem is that the variables "current_dev" and "current_partnum" are declared in both files now. This doesn't work. This patch now changes the names of those variable to more specific names: "current_mtd_dev" and "current_mtd_partnum". This is because this patch also changes the declaration from static to global, so that they can be used from both files. Please note that my first tests were not successful. The MTD devices selected via mtdparts are now accessed but I'm failing to see the directory listed via the "ls" command. Nothing is displayed. Perhaps I didn't generate the JFFS2 image correctly (I never used JFFS2 in U-Boot before). Not sure. Perhaps somebody else could take a look at this as well. I'll continue looking into this on Monday.

Note that struct part_info etc is in jffs2/load_kernel.h which is a bit misleading filename for that purpose, but that can be fixed later (tm). Signed-off-by: Ladislav Michl <ladis@linux-mips.org>
2009-03-20Separate mtdparts command from jffs2Stefan Roese
Currently the mtdparts commands are included in the jffs2 command support. This doesn't make sense anymore since other commands (e.g. UBI) use this infrastructure as well now. This patch separates the mtdparts commands from the jffs2 commands making it possible to only select mtdparts when no JFFS2 support is needed.
