* fs: write: fix writing on devicesSascha Hauer2009-07-301-3/+9
| | | | | | | | We can't truncate device files. Make sure that if we want to write beyond the device that the bytes that still fit into the device get written. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | We cannot check for < 0 in lseek, otherwise we get problems with files > 0x7fffffff Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* [fs]: set errno correctly for ioctl()Sascha Hauer2008-06-251-3/+4
|
* - introduce ioctl callSascha Hauer2008-06-064-10/+74
| | | | - pass open/close/lseek through to drivers
* This is Kconfig cleanup patch (not all configurations will use CFI, SPI, ↵Menon, Nishanth2008-05-122-2/+12
| | | | | | | RAMFS and DEVFS). * Enable CFI and SPI drivers menuconfig option to be able to disable them in menuconfig. * Introduce capability to disable ramfs and devfs.
* add missing null pointer check in unlink()Sascha Hauer2008-03-011-0/+5

* [general] Fixed crash in fs.h, when called with fsdrv.create == NULLCarsten Schlote2008-02-191-2/+5
| | | | | | | | | | When a nor0 devices has no partitions assigned, then a call to open() to create a file will jump with a NULL fct ptr. Much more cheching code is missing and pointers to function are jumped without any NULL ptr check. This must be fixed as well later. Signed-off-by: Carsten Schlote <c.schlote@konzeptpark.de>

| | | | | | With this function we can get a pointer to directly memory mapped devices like nor flash or RAM. Useful for bootm where we save one memcopy when the image is mappable

* svn_rev_420Sascha Hauer2007-07-054-24/+24
| | | | | | | | | | | - do more POSIX: - use DIR instead of struct dirent - use (struct dirent)->d_name instead of (struct dirent)->name - switch to a new layout for U_BOOT_CMD: - use C99 initializers to be able to add more fields to the command struct - add aliases for commands (needed mainly for help -> ? and test -> [ - This is not done for all commands yet, but the compiler will tell you ;)
* svn_rev_406Sascha Hauer2007-07-051-41/+105
| | | | let normalise path allocate the string instead of changing the original one
* svn_rev_396Sascha Hauer2007-07-051-4/+12
| | | | fix truncate (again). This still looks ugly
