* cmd_ubi: add write.part command, to write a volume in multiple partsPaul Burton2013-10-09-15/+48
| | | | | | | | | | | | | | | | | | | | | | | This allows you to write data to an UBI volume when the amount of memory available to write that data from is less than the total size of the data. For example, you may split a root filesystem UBIFS image into parts, provide the total size of the image to the first write.part command and then use multiple write.part commands to write the subsequent parts of the volume. This results in a sequence of commands akin to: ext4load mmc 0:1 0x80000000 rootfs.ubifs.0 ubi write.part 0x80000000 root 0x08000000 0x18000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.1 ubi write.part 0x80000000 root 0x08000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.2 ubi write.part 0x80000000 root 0x08000000 This would write 384MiB of data to the UBI volume 'root' whilst only requiring 128MiB of said data to be held in memory at a time.

* cmd_ubi: use int64_t volume size for 'ubi create'Paul Burton2013-10-09-8/+8
| | | | | | | | | int64_t matches the bytes field in struct ubi_mkvol_req to which the size is assigned. With the prior signed 32 bit integer, volumes were restricted to being less than 2GiB in size. Signed-off-by: Paul Burton <paul.burton@imgtec.com> Acked-by: Stefan Roese <sr@denx.de>

* Convert cmd_usage() calls in common to use a return valueSimon Glass2012-03-06-2/+2
| | | | | | | | | Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly. I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

* UBI: Fix error code handling in ubi commandsStefan Roese2011-03-21-72/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ubi commands returned negative error codes, resulting in the following error message on the prompt: "exit not allowed from main input shell." Negative error codes are not allowed. This patch now changes the UBI code to return positive error codes. Additionally "better" error codes are used, for example "ENOMEM" when no memory is available for the UBI volume creation any more. Also the output of some commands is enhanced: Before: => ubi read 100000 testvol 100000 Volume testvol found at volume id 0 read 1048576 bytes from volume 0 to 100000(buf address) => ubi write 100000 testvol 1000 Volume testvol found at volume id 0 After: => ubi read 100000 testvol 100000 Read 1048576 bytes from volume testvol to 00100000 => ubi write 100000 testvol 1000 4096 bytes written to volume testvol Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>

* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-8/+4
| | | | | | | | | | | | | | | | Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* cmd_ubi: Fix uninitialized variable warningPeter Tyser2010-04-09-1/+1
| | | | | | | | | | | | gcc 3.4.6 previously reported the following error on many MIPS boards which utilize UBI: cmd_ubi.c:193: warning: 'vol' might be used uninitialized in this function The current code is structured such that 'vol' will never be used when it is NULL anyway, but gcc isn't smart enough to figure this out.

* General help message cleanupWolfgang Denk2009-06-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ubi: Remove flash selection parameter (nor|nand|onenand) from "ubi part"Stefan Roese2009-04-28-48/+25
| | | | | | | | | | | | | | | | | | | | | | This patch removes the now unnecessary flash type parameter from the "ubi part" command. Currently the user has to define the type of flash he will be using UBI on. Example: => ubi part nor partition1 With this patch this type parameter is not needed anymore. The user can now select the partition directly without the flash type paramter. Example: => ubi part partition1 This breaks backward compatibility right now because of the change in the command syntax. But UBI support is still quite fresh and the advantage of this new command is syntax big enough for this change. Additionally the code is much cleaner now.

* UBI/cfi-mtd: Fix mtd name for multiple chipsAndreas Huber2009-04-04-5/+21
| | | | | | | | | | | | | On platforms with multiple NOR chips, currently only the first one can be selected using the "ubi part" command. This patch fixes this problem by using different names for the NOR "mtd devices". It also changes the name of the NOR MTD device from "cfi-mtd" to "norX" (X indexing the device numer) to better match the mtdparts defaults.
