| | | | | | | | | | | | | | | | | | | | | | | | | | 'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>

|/ | | | | | | | | | | | Flush UART3 xmit on enable if TEMT is broken On some OMAP3 devices when UART3 is configured for boot mode before SPL starts only THRE bit is set.

| * serial/ns16550: add an option to avoid hanging on broken platformsJavier Martinez Canillas2013-01-10-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms (e.g. IGEPv2 board) has a broken ns16550 UART that does not set the TEMT bit when the transmitter is empty in SPL. This makes U-Boot to hang while waiting for TEMT to be set. Add a new option to avoid this: CONFIG_SYS_NS16550_BROKEN_TEMT 16550 UART set the Transmitter Empty (TEMT) Bit when all output has finished and the transmitter is totally empty. U-Boot waits for this bit to be set to initialize the serial console. On some broken platforms this bit is not set in SPL making U-Boot to hang while waiting for TEMT. Define this option to avoid it.

* | serial: serial_sh: bugfix: autoboot fails if serial console is not connectedTetsuyuki Kobayashi2012-11-30-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On kzm9g board (rmobile SoC), autoboot fails if serial console cable is not connected. When serial cable is not connected, serial error occurs and some garbage comes in data register. sh_serial_tstc() in serial_sh.c does not check error status and misunderstand there is some input data. It is the reason that autoboot fails. This patch adds checking error status in sh_serial_tstc(). This patch is based on v2013.01-rc1 tag of u-boot master git.

* | 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: Reorder get_current()Marek Vasut2012-10-17-9/+12
| | | | | | | | | | | | | | | | | | | | Reorder the get_current() function to make it a bit more readable. The code does not grow and there is minor change in the code logic, where dev != NULL is now checked in any case.

* | serial: Reorder serial_assign()Marek Vasut2012-10-17-5/+6
| | | | | | | | | | | | | | | | | | | | Reorder serial_assign() function to get rid of the extra level of indentation. Also, adjust the return value to be -EINVAL instead of positive one to be more consistent.

* | serial: Use default_serial_puts() in driversMarek Vasut2012-10-17-167/+22
| | | | | | | | | | | | | | | | | | | | Replace the in-place ad-hoc implementation of serial_puts() within the drivers with default_serial_puts() call. This cuts down on the code duplication quite a bit. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tom Rini <trini@ti.com>
* | serial: Implement default_serial_puts()Marek Vasut2012-10-17-0/+7
|/ | | | | | | | | | | | | | U-Boot contains a lot of duplicit implementations of serial_puts() call which just pipes single characters into the port in loop. Implement function that does this behavior into common code, so others can make easy use of it. This function is called default_serial_puts() and it's sole purpose is to call putc() in loop on the whole string passed to it.

* serial: Enhance the manual relocationMarek Vasut2012-10-15-6/+14
| | | | | | | | | | | | | Enhance the manual relocation of drivers operations structure by checking if the entries are NULL and increment them only if they are not. This allows for setting any entry to NULL and it will survive the manual relocation.
