serial: Remove duplicated line in Makefile

The line "-obj-$(CONFIG_STM32_SERIAL) += serial_stm32.o" is found twice in Makefile. Fixes: ae74de0dfd45 ("serial: stm32: Rename serial_stm32x7.c to serial_stm32.c" Signed-off-by: Patrice Chotard Acked-by: Vikas Manocha Reviewed-by: Simon Glass

serial: Fix Makefile during SPL and TPL build

2018-04-11T17:22:05Z

This patch fixes a situation where CONFIG_DM_SERIAL is enabled for regular U-Boot and SPL, but not for TPL. In that case, the build will try to include serial-uclass into the TPL nonetheless, because CONFIG_DM_SERIAL is set. The solution is to check if the build is for SPL or TPL and in that case, check if CONFIG_$(SPL_TPL_)DM_SERIAL is also set. Only in that case, include serial-uclass.c . If the build is for regular U-Boot, CONFIG_BUILD is not set, so only check if CONFIG_DM_SERIAL is set and if so, include serial-uclass.c Signed-off-by: Marek Vasut Cc: Simon Glass Cc: Tom Rini

bcm2835_pl011_serial: Add BCM2835 specific serial driver

2018-01-28T17:27:36Z

On bcm2835 we need to ensure we only access serial devices that are muxed to the serial output pins of the pin header. To achieve this for the pl011 device, add a bcm2835 specific pl011 wrapper device that does this check but otherwise behaves like a pl011 device. Signed-off-by: Alexander Graf

serial: stm32: Rename serial_stm32x7.c to serial_stm32.c

Now this driver is used across stm32f4, stm32f7 and stm32h7 SoCs family, give it a generic name. Signed-off-by: Patrice Chotard Reviewed-by: Vikas Manocha

serial: nulldev: Add nulldev serial driver

2017-09-13T13:24:24Z

Some device the serial console's initialization cannot run early during the boot process. Hence, nulldev serial device is helpful on that situation. For example, if the serial module was implemented in FPGA. Serial initialization is prohibited to run until the FPGA was programmed. This commit is to adding nulldev serial driver. This will allows the default console to be specified as a nulldev. Signed-off-by: Joe Hershberger Signed-off-by: Keng Soon Cheah Cc: Chen Yee Chew

serial: Add serial driver for Intel MID

2017-04-10T02:02:03Z

Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

dm: serial: Allow driver-model serial to be disabled for TPL

2017-04-05T20:36:59Z

Add separate enable/disable controls for driver-model serial. While this is generally enabled in SPL it may not be in TPL, since serial output can be obtained with the debug UART with minimal code size. Signed-off-by: Simon Glass
