serial: serial_cortina: add UART DM driver for CAxxxx SoCs

Add serial UART driver support for all Cortina Access CAxxxx family of SoCs. Reviewed-by: Daniel Schwierzeck Signed-off-by: Jason Li Signed-off-by: Alex Nemirovsky

x86: serial: Add a coreboot serial driver

2020-02-03T17:19:25Z

Coreboot can provide information about the serial device in use on a platform. Add a driver that uses this information to produce a working UART. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

serial: ns16550: Support run-time configuration

2020-02-03T17:19:13Z

At present this driver uses an assortment of CONFIG options to control how it accesses the hardware. This is painful for platforms that are supposed to be controlled by a device tree or a previous-stage bootloader. Add a new CONFIG option to enable fully dynamic configuration. This controls register spacing, size, offset and endianness.

Add dependencies for MALLOC_F and OF_LIBFDT

2020-01-16T00:50:31Z

Some features implicitly depended on MALLOC_F and OF_LIBFDT and would fail at link-time if these features were not enabled. Signed-off-by: Sean Anderson

Kconfig: make TPL_DM_SERIAL depend on TPL_DM

2019-12-03T13:43:23Z

This missing dependency seems like an oversight, since all other TPL_DM_* options have it. Signed-off-by: Thomas Hebb

serial: Kconfig: make MXC_UART usable for MX7 and IMX8M

i.MX7 and i.MX8M use mxc uart driver, so let's make the SoC could use MXC_UART kconfig. Signed-off-by: Peng Fan Reviewed-by: Ye Li

Kconfig: Varios: Fix more SPL, TPL dependencies

2019-08-26T15:46:29Z

Several options are presenting themselves on a various boards where the options are clearly not used. (ie, SPL/TPL options when SPL or TPL are not defined) This patch is not attempting to be a complete list of items, but more like low hanging fruit. In some instances, I wasn't sure of DM was required, so I simply made them SPL or TPL. This patch attempts to reduce some of the menuconfig noise by defining dependencies so they don't appear when not used. Signed-off-by: Adam Ford

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL

2019-04-09T06:28:50Z

This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed. Signed-off-by: Stefan Roese Cc: Heiko Schocher Cc: Andreas Bießmann Cc: Eugen Hristev

serial: ns16550: fix debug uart putc called before init

2019-01-15T20:28:52Z

If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt Reviewed-by: Simon Glass
