When compile-testing an allmodconfig kernel for a platform without sh-sci serial ports, the SERIAL_SH_SCI_NR_UARTS symbol of type "int" doesn't get assigned a numerical default value, but an empty string, leading to a build failure: .config:3814:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS ... make[3]: *** [silentoldconfig] Error 1 Fix this by explicitly providing a default value of 2, like before.

2017-12-15tty: serial: sh-sci: Hide DMA config questionGeert Uytterhoeven1-1/+2
On most Renesas ARM platforms, the SCIF serial ports can be used with DMA, so most users will want DMA support to be enabled. On SuperH platforms, SCI(F) serial ports cannot be used with DMA yet (see also commit 219fb0c1436e4893 ("serial: sh-sci: Remove the platform data dma slave rx/tx channel IDs")), so users will want it disabled to reduce kernel size. Hence follow the above rationale to configure the default, unless CONFIG_EXPERT is enabled.

Nios2 currently uses its own early printk implementation, rather than using unified earlycon support to show boot messages on altera_uart. Add earlycon support to altera_uart so that other archs may use it.

2017-03-17uartlite: Adding a kernel parameter for the number of uartlitesSam Povilus1-0/+9
The number of uartlites should be set by a kernel parameter instead of using a #define. This allows the user to set the number of uartlites using only kconfig and not modifying kernel source. The uartlite is used by FPGAs that support a basically unlimited number of uarts so limiting it at 16 dosn't make sense as users might need more than that.

2016-10-27serial: rewrite pxa2xx-uart to use 8250_coreSergey Yanovich1-2/+15
pxa2xx-uart was a separate uart platform driver. It was declaring the same device names and numbers as 8250 driver. As a result, it was impossible to use 8250 driver on PXA SoCs. Upon closer examination pxa2xx-uart turned out to be a clone of 8250_core driver. Workaround for Erratum #19 according to Marvel(R) PXA270M Processor Specification Update (April 19, 2010) is dropped. 8250_core reads from FIFO immediately after checking DR bit in LSR. The patch leaves the original SERIAL_PXA driver around. The original driver is just marked DEPRECATED in Kconfig and C source. When the original driver is considered safe to remove, no changes to SERIAL_8250 will be necessary. Compiling SERIAL_8250_CONSOLE and SERIAL_PXA_CONSOLE even without SERIAL_8250_PXA breaks console for SERIAL_PXA. For this reasons, the new and the original drivers are made mutually exclusive.

2015-10-04serial: imx: add earlycon supportLucas Stach1-0/+1
Earlycon allows to have an early debugging console that doesn't need to be statically configured in the kernel config, like earlyprintk, but is set up through the stdout-path DT property. This allows to have the early debugging always built into the kernel and enabled on demand without clashing between different boards or architectures.
