* serial: add static directive to local functionsMasahiro Yamada2014-10-23-14/+7
| | | | | | | | | | | | The functions _serial_putc, _serial_putc_raw, _serial_puts, _serial_getc, _serial_tstc, _serial_setbrg are defined and used locally in each of serial_ns16550.c and serial_s3c24x0.c. Add static directive to them and remove declarations from include/common.h. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
* dm: serial: Move baud rate calculation to ns16550.cSimon Glass2014-09-10-10/+4
| | | | | | | Move the function that calculates the baud rate divisor into ns16550.c so it can be used by that file. Signed-off-by: Simon Glass <sjg@chromium.org>
* omap: clean-up dead configsMasahiro Yamada2014-08-09-9/+0
| | | | | | | | | | | | | | The following configs are not defined at all. - CONFIG_OMAP1510 - CONFIG_OMAP_1510P1 - CONFIG_OMAP_SX1 - CONFIG_OMAP3_DMA - CONFIG_OMAP3_ZOOM2 - CONFIG_OMAP_INNOVATOR Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Tom Rini <trini@ti.com>
* serial: ns16550: use a const variable instead of macroMasahiro Yamada2014-07-22-3/+3
| | | | | | | | Just for type checking. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Marek Vasut <marex@denx.de> Acked-by: Marek Vasut <marex@denx.de>
* serial: ns16550: use DIV_ROUND_CLOSEST macro to compute the divisorMasahiro Yamada2014-07-22-7/+3
| | | | | | | | | The function still returns the same value. The comment block is no longer necessary because our intention is clear enough by using DIV_ROUND_CLOSEST() macro. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* serial: ns16550: drop CONFIG_OMAP1610 from the special caseMasahiro Yamada2014-07-22-6/+0
| | | | | | | | | | | | | | | | | | | If CONFIG_OMAP1610 is defined, the code returning the fixed value (26) is enabled. But this case is covered by the following code. (CONFIG_SYS_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) / (MODE_X_DIV * gd->baudrate) = (48000000 + (115200 * (16 / 2))) / (16 * 115200) = 48921600 / 1843200 = 26 The "#ifdef CONFIG_OMAP1610" was added by commit 6f21347d more than ten years ago. In those days, the divide-and-round was not used. I guess that is why this weird code was added here.

* arm: Remove OMAP2420H4 and all omap24xx supportTom Rini2013-06-10-5/+0
| | | | | | | | | The omap2420H4 was the only mainline omap24xx board. Prior to being fixed by Jon Hunter in time for v2013.04 it had been functionally broken for a very long time. Remove this board as there's not been interest in it in U-Boot for quite a long time. Signed-off-by: Tom Rini <trini@ti.com>
* serial/ns16550: don't generate functions for undefined portsScott Wood2013-02-19-0/+12
| | | | | | | This saved 640 bytes on MPC8536DS (a board with two of the six ports defined). Signed-off-by: Scott Wood <scottwood@freescale.com>
* serial/ns16550: don't build serial_ns16550 with MIN_FUNCTIONSScott Wood2012-11-26-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic ns16550 output code without pulling in things not needed by the SPL. This previously only worked with non-MULTI configs. Recently MULTI was made mandatory, and MIN_FUNCTIONS fails like this: drivers/serial/libserial.o: In function `calc_divisor.clone.0': serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq' drivers/serial/libserial.o: In function `_serial_getc': (.text._serial_getc+0x30): undefined reference to `NS16550_getc' drivers/serial/libserial.o: In function `_serial_tstc': (.text._serial_tstc+0x30): undefined reference to `NS16550_tstc' drivers/serial/libserial.o: In function `_serial_setbrg': (.text._serial_setbrg+0x3c): undefined reference to `NS16550_reinit' make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1 make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2 With MIN_FUNCTIONS we don't need anything from this file, so don't build it. The conditional needs to be in the file itself rather than the makefile, because the config symbols are only imported to the makefiles once, not separately for the SPL phase of the build.

* serial: Remove CONFIG_SERIAL_MULTI from serial driversMarek Vasut2012-10-15-95/+0
| | | | | | | | | | | | Remove the support for not-CONFIG_SERIAL_MULTI part from serial port drivers and some board files. Since CONFIG_SERIAL_MULTI is now enabled by default, that part is a dead code. Remove it.

* serial: ns16550: Rename serial.c to serial_ns16550.cMarek Vasut2012-10-15-0/+359
This serial driver had wrong name of the source file for some time now. The name of the driver was serial.c instead of any more logical and fitting name. Thus, rename the driver source file to serial_ns16550.c and be done with it.
