* treewide: Make locally used functions staticSascha Hauer2019-03-181-1/+1
| | | | | | | Many functions are only used locally but still are globally visible. Make these function static. Avoids warnings generated with -Wmissing-prototypes Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* devfs: Drop dev_lseek_default()Andrey Smirnov2019-01-292-2/+0
| | | | | | | | | | | | | | | | | | | | | Only the following cdevs do not declare an .lseek() operation: - Console devices in common/console.c - Firmware framework in common/firmware.c - JTAG driver in drivers/misc/jtag.c - UBI in drivers/mtd/ubi/barebox.c Of those four, first two are marked DEVFS_IS_CHARACTER_DEV and implement only .write() operation and the last two don't implement anything but .ioctl(). While there's probably no meaningful way to use lseek() against any of those devices, there doesn't seem to be any harm in allowing it either. Change devfs_lseek() to ignore absense of .lseek() callback and drop dev_lseek_default() and all references to it in the codebase.

* rename file_operations -> cdev_operationsSascha Hauer2018-04-062-2/+2
| | | | | | | | Linux also has struct file_operations which are something different. Rename our file_operations to cdev_operations which better matches what we have. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-152-2/+2
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

export for each device via param the familly id (fid) the id the full reg_num so for simple 64bit memory rom(ds2401/ds2411/ds1990*) no need driver. Based on linux implementation, cleaned and re-implement the master/slave support to use the device/driver model correctly.
