| * fs: let truncate take a loff_t argumentSascha Hauer2019-02-061-1/+1
| | | | | | | | | | | | | | loff_t is the correct type for file sizes. Use it to allow to truncate to sizes bigger than 32bit. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * fs: devfs: Change .lseek callbacks to return 'int'Andrey Smirnov2019-02-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | Returning requested offset from .lseek() callback doesn't really give us any new information while bringing unnecessary complications. Change all .lseek() types (both in struct struct cdev_operations and in struct fs_driver_d) to return 'int' and adjust the rest of the codebase accordingly.

| * devfs: Drop dev_lseek_default()Andrey Smirnov2019-01-291-5/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Relevant part of Linux commit dad2256269cb: NAND_BBT_SCANEMPTY is a strange, badly-supported option with omap as its single remaining user. NAND_BBT_SCANEMPTY was likely used by accident in omap2[1]. And anyway, omap2 doesn't scan the chip for bad blocks (courtesy of NAND_SKIP_BBTSCAN), and so its use of this option is irrelevant. This patch drops the NAND_BBT_SCANEMPTY option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux commit b32843b772db adapted for Barebox: nand_base.c shouldn't have to know the implementation details of nand_bbt's in-memory BBT. Specifically, nand_base shouldn't perform the bit masking and shifting to isolate a BBT entry. Instead, just move some of the BBT code into a new nand_markbad_bbt() interface. This interface allows external users (i.e., nand_base) to mark a single block as bad in the BBT. Then nand_bbt will take care of modifying the in-memory BBT and updating the flash-based BBT (if applicable).

The arch I am working on atm also needs support for muldi3 which is not present as a generic version right now. This patch adds the generic version from latest linux v4.20 to barebox and lets the archs select it in their Kconfig so they don't need to provide it themself.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds device tree support to the davinci-emac driver. This needs some changes to the driver as the device has four different resources. Three of them are merged into a single resource in the dts files with the node providing offsets for the different resources to base address. The mdio node is found separately in the dts, so we have to split this out to a different driver. Since this driver has been unused previously, we do not bother maintaining two different probe methods and remove platform probe support at the same time.

This patch also adds error messages and error returns to the various callers of resolv() which used to just continue with a zero IP and let the user figure out what went wrong.
