* fs: implement size/fatsize/ext4sizeStephen Warren2014-08-09-0/+43
| | | | | | | | | | These commands may be used to determine the size of a file without actually reading the whole file content into memory. This may be used to determine if the file will fit into the memory buffer that will contain it. In particular, the DFU code will use it for this purpose in the next commit.

* catch wrong load address passed to fatload / ext2loadPavel Machek2014-07-22-1/+4
| | | | | | | | If filename is passed instead of address to ext2load or fatload, u-boot silently accepts that, and uses 0 for load address and default filename from environment. That is confusing, display help instead. Signed-off-by: Pavel Machek <pavel@denx.de>

* fs: don't pass NULL dev_desc to most filesystemsStephen Warren2014-02-19-0/+16
| | | | | | | | | | FAT and ext4 expect that the passed in block device descriptor not be NULL. This causes problems on sandbox, where get_device_and_partition() succeeds for the "host" device, yet passes back a NULL device descriptor. Add special handling for this situation, so that the generic filesystem commands operate as expected on sandbox. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* fs: implement infrastructure for an 'exists' functionStephen Warren2014-02-19-0/+32
| | | | | | | | | | | | | | | | | | | | | | | This could be used in scripts such as: if test -e mmc 0:1 /boot/boot.scr; then load mmc 0:1 ${scriptaddr} /boot/boot.scr source ${scriptaddr} fi rather than: if load mmc 0:1 ${scriptaddr} /boot/boot.scr; then source ${scriptaddr} fi This prevents errors being printed by attempts to load non-existent files, which can be important when checking for a large set of files, such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf, /boot.scr.uimg, /boot.scr, /extlinux.conf.

* fs: fix generic save command implementationStephen Warren2014-02-19-6/+3
| | | | | | | | | | | | | | | | | | | | Fix a few issues with the generic "save" shell command, and fs_write() function. 1) fstypes[].write wasn't filled in for some file-systems, and isn't checked when used, which could cause crashes/... if executing save on e.g. fat/ext filesystems. 2) fs_write() requires the length argument to be non-zero, since it needs to know exactly how many bytes to write. Adjust the comments and code according to this. 3) fs_write() wasn't prototyped in <fs.h> like other generic functions; other code should be able to call this directly rather than invoking the "save" shell command.

* Fix number base handling of "load" commandWolfgang Denk2013-10-07-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As documented, almost all U-Boot commands expect numbers to be entered in hexadecimal input format. (Exception: for historical reasons, the "sleep" command takes its argument in decimal input format.) This rule was broken for the "load" command; for details please see especially commits 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" and 3f83c87 "fs: fix number base behaviour change in fatload/ext*load". In the result, the load command would always require an explicit "0x" prefix for regular (i. e. base 16 formatted) input. Change this to use the standard notation of base 16 input format. While strictly speaking this is a change of the user interface, we hope that it will not cause trouble. Stephen Warren comments (see [1]): I suppose you can change the behaviour if you want; anyone writing "0x..." for their values presumably won't be affected, and if people really do assume all values in U-Boot are in hex, presumably nobody currently relies upon using non-prefixed values with the generic load command, since it doesn't work like that right now.

* sandbox: fs: Add support for saving files to host filesystemSimon Glass2013-05-01-0/+1
| | | | | | | | | | | | This allows write of files from the host filesystem in sandbox. There is currently no concept of overwriting the file and removing its existing contents - all writing is done on top of what is there. This means that writing 10 bytes to the start of a 1KB file will only update those 10 bytes, not truncate the file to 10 byte slong. If the file does not exist it is created.

* fs: rename fsload command to loadStephen Warren2012-11-04-1/+1
| | | | | | | | | | | When the generic filesystem load command "fsload" was written, I felt that "load" was too generic of a name for it, since many other similar commands already existed. However, it turns out that there is already an "fsload" command, so that name cannot be used. Rename the new "fsload" to plain "load" to avoid the conflict. At least anyone who's used a Basic interpreter should feel familiar with the name! Signed-off-by: Stephen Warren <swarren@nvidia.com>
* fs: fix number base behaviour change in fatload/ext*loadStephen Warren2012-11-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" unified the implementation of fatload and ext*load with the new command fsload. However, this altered the interpretation of command-line numbers from always being base-16, to requiring a "0x" prefix for base-16 numbers. Enhance do_fsload() to allow commands to specify which base to use. Use base 0, thus requiring a "0x" prefix for the new fsload command. This feels much cleaner than assuming base 16. Use base 16 for the pre-existing fatload and ext*load to prevent a change in behaviour. Use base 16 exclusively for the loadaddr environment variable, since that variable is interpreted in multiple places, so we don't want the behaviour to change. Update command help text to make it clear where numbers are assumed to be hex, and where an explicit "0x" prefix is required.

* fs: fix do_fsload() handling of optional argumentsStephen Warren2012-11-04-3/+7
| | | | | | | | | | | | | | | | | | Most arguments to the shell command do_fsload() implements are optional. Fix the minimum argc check to respect that. Cater for the situation where argv[2] is not provided. Enhance both do_fsload() and do_ls() to check the maximum number of arguments too. While this check would typically be implemented via U_BOOT_CMD()'s max_args parameter, if these functions are called directly, then that check won't exist. Finally, alter do_ls() to check (argc >= 4) rather than (argc == 4) so that if the function is enhanced to allow extra arguments in the future, this test won't need to be changed at that time.

* fs: add filesystem switch libary, implement ls and fsload commandsStephen Warren2012-10-29-0/+308
Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load}, and transparently handle either file-system. This scheme could easily be extended to other filesystem types; I only didn't do it for zfs because I don't have any filesystems of that type to test with. Replace the implementation of {fat,ext[24]}{ls,load} with this new code too. Signed-off-by: Stephen Warren <swarren@nvidia.com>
