2021-01-24serial: add uart driver for MediaTek MT7620 SoCWeijie Gao1-0/+20
This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL.

U-Boot DM model probe only single device at a time which is enabled and configured using device tree or platform data method. PL011 UART IP is SBSA compliant and firmware does the serial port set-up, initialization and let the kernel use UART port for sending and receiving characters. Normally software talk to one serial port time but some LayerScape platform require all the UART devices enabled in Linux for various use case. Adding support to probe all enabled serial devices like SBSA compliant PL011 UART ports probe and initialization by firmware.

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.

2019-01-15serial: ns16550: fix debug uart putc called before initSimon Goldschmidt1-0/+12
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).

Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.
