2013-01-10serial/ns16550: add an option to avoid hanging on broken platformsJavier Martinez Canillas
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.

2012-11-30serial: serial_sh: bugfix: autoboot fails if serial console is not connectedTetsuyuki Kobayashi
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.

2012-11-26serial/ns16550: don't build serial_ns16550 with MIN_FUNCTIONSScott Wood
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.
