* video: Drop DEV_FLAGS_SYSTEM flagBin Meng2015-11-051-1/+1
| | | | | | DEV_FLAGS_SYSTEM does not have any actual meaning, hence drop it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
* linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-231-1/+1
| | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-231-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
* serial: bfin: Flip the jtag serial console to CONFIG_SERIAL_MULTIMarek Vasut2012-10-151-7/+30
| | | | | | | | | | | | | | | | | | | Rework the emulation of serial console via JTAG from simple ad-hoc implementation of serial port routines to CONFIG_SERIAL_MULTI and enable CONFIG_SERIAL_MULTI unconditionally for blackfin. In order for the JTAG serial console to take precedence over all other serial ports available in system, implement override for default_serial_console call returning this JTAG serial console. This brings in a bit of a growth of size, but eventually will allow us to unconditionally enable CONFIG_SERIAL_MULTI throughout the whole U-Boot and maintain only one serial subsystem.

* Blackfin: jtag-console: handle newline stuffingMike Frysinger2010-07-251-9/+32
| | | | | | | | | | Serial devices currently have to manually stuff \r after every \n found, but this is a bit more difficult with the jtag console since we process everything in chunks of 4 bit. So we have to scan & stuff the whole string rather than what most serial drivers do which is output on a byte per byte basis. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: jtag-console: add debug markersMike Frysinger2010-07-251-1/+27
| | | | | | | | | | While we're in here, add some useful debug points. We need custom debug statements because we need the output to only go to the serial port. If we used the standard debug helpers, the output would also go to the stdout (which would be the jtag console) and make it hard to figure out what is going where exactly.

* Blackfin: jtag-console: robustify against missing peerMike Frysinger2010-07-251-8/+32
| | | | | | | | | If the other side isn't listening, we should reset the state to ignore the whole message and not just the part we missed. This makes it easier to connect at any time to the jtag console without worrying about the two sides getting out of sync and thus sending garbage back and forth.
