* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* jffs2: fix hangs/crashs when not using CONFIG_JFFS2_PART_SIZEMike Frysinger2010-01-26-2/+2
| | | | | | | | | | Commit b5b004ad8a0ac6f98bd5708ec8b22fbddd1c1042 caused the sector_size to be calculated incorrectly when the part size was not hardcoded. This is because the new code relied on part->size but tried to do the calculation before it was initialized properly, and it did not take into consideration the magic SIZE_REMAINING define.

* Remove legacy NAND and disk on chip code.Scott Wood2009-07-16-15/+0
| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

* General help message cleanupWolfgang Denk2009-06-12-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* jffs2/mtdparts: Fix problem with usage from JFFS2 and MTDPARTS togetherStefan Roese2009-05-28-17/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Separate mtdparts command from jffs2Stefan Roese2009-03-20-1725/+6
| | | | | | | | | | | 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.

* jffs2: Fix zero sector_size when not using CONFIG_JFFS2_CMDLINETomasz Figa2009-01-27-0/+92
| | | | | | | | | | | | | | | | This patch fixes a bug (?) introduced after inclusion of the new JFFS2 code. When not using CONFIG_JFFS2_CMDLINE, the code in cmd_jffs2.c doesn't fill in part->sector_size (keeping it as 0), but a correct value is needed by the code in jffs2_1pass.c. This causes all JFFS2 accesses to be in the same place of the memory, what obviously means impossibility to use the JFFS2 partition. This problem is fixed in this patch by including sector size calculation in non-CONFIG_JFFS2_CMDLINE mtdparts_init variant. Signed-off-by: Tomasz Figa <tomasz.figa_at_gmail.com>
