* serial: pl01x: drain PL01x FIFO before baudrate changeLinus Walleij2011-10-22-0/+10
| | | | | | | | | Not draining the FIFO and waiting for the UART to be non-busy before changing baudrate results in crap characters on the console, so let's wait for the FIFO to drain and the last character to be clocked out before we do that. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* Move timestamp and version files into 'generated' subdirSimon Glass2011-10-17-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a rather subtle build problem where the build time stamp is not updated for out-of-tree builds if there exists an in-tree build which has a valid timestamp file. So if you do an in-tree build, then an out-of-tree build your timestamp will not change. The correct timestamp_autogenerated.h lives in the object tree, but it is not always found there. The source still lives in the source tree and when compiling version.h, it includes timestamp_autogenerated.h. Since the current directory is always searched first, this will come from the source tree rather than the object tree if it exists there. This affects dependency generation also, which means that common/cmd_version.o will not even be rebuilt if you have ever done an in-tree build. A similar problem exists with the version file. This change moves both files into the 'generated' subdir, which is already used for asm-offsets.h. Then timestamp.h and version.h are updated to include the files from there. There are other places where these generated files are included, but I cannot see why these don't just use the timestamp.h and version.h headers. So this change also tidies that up. I have tested this with in- and out-of-tree builds, but not SPL. I have looked at various other options for fixing this, including sed on the dep files, -I- and -include flags to gcc, but I don't think they can be made to work. Comments welcome.

This is especially useful for SoC devices that implement 16550 compatible uarts but that have peripheral access width constraints. Signed-off-by: Dave Aldridge <fovsoft@gmail.com>

* serial: drop useless ctlr fieldMike Frysinger2011-07-26-20/+14
| | | | | | | | | | | | | | | | | | | The multi serial support has a "ctlr" field which almost no one uses, but everyone is forced to set to useless strings. So punt it. Funny enough, the only code that actually reads this field (the mpc8xx driver) has a typo where it meant to look for the SCC driver. Fix it while converting the check to use the name field.

| | | | | | | | | | | | | | | | | Rather than sticking arch/board/driver specific logic in the common serial code, push it all out to the respective drivers.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

* ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boardsStefan Roese2010-10-13-0/+9
| | | | | | | | | | | | | | | | | | | | Call watchdog_reset() upon newline. This is done here in putc since the environment code uses a single puts() to print the complete envrironment upon "printenv". So we can't put this watchdog call in puts(). This is needed for boards with a very short watchdog timeout, like the lwmon5 with a 100ms timeout. Without this patch this board resets in the commands with long outputs, like "printenv" or "fdt print". Note that the image size is not increased with this patch when CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler optimizes this additional code away.
