* sandbox: Add host filesystemSimon Glass2013-03-04-0/+10
| | | | | | | This allows reading of files from the host filesystem in sandbox. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* fs: Move ls and read methods into ext4, fatSimon Glass2013-03-04-110/+8
| | | | | | | | | It doesn't make a lot of sense to have these methods in fs.c. They are filesystem-specific, not generic code. Add each to the relevant filesystem and remove the associated #ifdefs in fs.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* fs: Use map_sysmem() on readSimon Glass2013-03-04-8/+15
| | | | | | | | This allows us to use filesystems on sandbox. It has no effect on other architectures. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* fs: Tell probe functions where to put their resultsSimon Glass2013-03-04-8/+12
| | | | | | | | | | Rather than rely on global variables for the probe functions, pass in the information that we need filled in. This allows us to potentially keep the variables private to fs.c in the future, and the meaning of the probe function is clearer.

* fs: Use filesystem methods instead of switch()Simon Glass2013-03-04-34/+26
| | | | | | | | | | We can use the available methods and avoid using switch(). When the filesystem is not supported, we fall through to the 'unsupported' methods: fs_probe_unsupported() prints an error, so the others do not need to.

* fs: Fully populate the filesystem method structSimon Glass2013-03-04-9/+47
| | | | | | | | | There is a structure in fs.c with just a probe method. By adding methods for other operations, we can avoid lots of #ifdefs and switch()s. As a first step, create the structure ready for use. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>

* 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>
