2014-09-08serial: lpuart: add 32-bit registers lpuart supportJingchang Lu
On vybrid, lpuart's registers are 8-bit. On LS102xA, lpuart's registers are 32-bit. This patch adds the support for 32-bit registers on LS102xA. Signed-off-by: Jingchang Lu <jingchang.lu@freescale.com> Signed-off-by: Yuan Yao <yao.yuan@freescale.com>
2014-08-30serial: move nios2-yanu.h into opencores_yanu driverThomas Chou
The nios2-yanu.h contains hardware registers and bits of opencores yanu. As there is no other user of this header , it should be moved into the driver. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> CC: Renato Andreola <renato.andreola@imagos.it>
2014-08-30nios2: divide nios2-io.h into each specific drivers and remove itThomas Chou
The nios2-io.h defines hardware registers and bits of several FPGA IP cores. It could be divided in to the specific drivers, including altera timer, altera sysid, altera uart and altera jtag uart. The altera pio and altera spi drivers use their own hardware definitions. The removal of nios2-io.h will help modularity and maintenance. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

2014-07-23Add a flag indicating when the serial console is readySimon Glass
For sandbox we have a fallback console which is used very early in U-Boot, before serial drivers are available. Rather than try to guess when to switch to the real console, add a flag so we can be sure. This makes sure that sandbox can always output a panic() message, for example, and avoids silent failure (which is very annoying in sandbox). Signed-off-by: Simon Glass <sjg@chromium.org>
2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
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>

2014-07-22serial: ns16550: drop CONFIG_OMAP1610 from the special caseMasahiro Yamada
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.

2014-05-28serial_mxc: disable new features of autobaud detectionEric Nelson
Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x reference manuals as follows: Autobaud Detection Not Improved-. Disables new features of autobaud detection (See Baud Rate Automatic Detection Protocol, for more details). 0 Autobaud detection new features selected 1 Keep old autobaud detection mechanism On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features" occasionally cause the receiver to get out of sync and continuously produce received characters of '\xff'. This patch disables the "new feature" on all boards, since there's no support for auto-baud in U-Boot on any of them.
