serial: sh: Use the clock framework to obtain clock config

2017-08-02T19:26:25+00:00

Since we now have clock driver on the RCar Gen3 , obtain the clock
configuration using the clock framework functions. In case this
fails, fall back to the original code for pulling the clock config
directly out of OF.

serial: sh: Convert to Kconfig

2017-08-02T19:26:24+00:00

Convert the SH Serial to Kconfig using tools/moveconfig.py tool
and a bit of manual adjustment to cater for failed conversions.

dm: console: Check for serial devices properly

2017-07-31T16:21:40+00:00

With driver model the serial device is often not called "serial". Mark
driver-model stdio devices so that they can be detected and we can look up
the uclass. This is a more reliable way of finding out whether the console
is connected to a serial device or not.

spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

2017-07-27T12:59:03+00:00

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

serial: stm32x7: add clk_get_rate() support

2017-07-26T15:28:08+00:00

Replace proprietary clock_get() by clk_get_rate()
The stm32x7 serial driver is now "generic" and can be used
by other STM32 SoCs.

serial: stm32x7: migrate serial struct to driver

2017-07-26T15:26:54+00:00

This allow to remove include/dm/platform_data/serial_stm32x7.h
which was included in the past by stm32x7 driver and by
stm32f746-disco.c board file.
Since patch 42bf5e7c27 "serial: stm32f7: add device tree support"
this file is no more needed in board file.

serial: ns16550: Add RX interrupt buffer support

2017-07-23T21:04:46+00:00

Pasting longer lines into the U-Boot console prompt sometimes leads to
characters missing. One problem here is the small 16-byte FIFO of the
legacy NS16550 UART, e.g. on x86 platforms.

This patch now introduces a Kconfig option to enable RX interrupt
buffer support for NS16550 style UARTs. With this option enabled, I was
able paste really long lines into the U-Boot console, without any
characters missing.
