serial: stm32x7: add STM32F4 support

2017-10-08T20:19:56+00:00

stm32f4 doesn't support FIFO and OVERRUN feature.
The enable bit is not at the same location in CR1
register than for STM32F7 and STM32H7.

serial: nulldev: Add nulldev serial driver

2017-09-13T13:24:24+00:00

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.

serial: serial-uclass: Add generic serial RX buffer support

2017-08-24T03:00:47+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 buffer support
for all DM based serial drivers. With this option enabled, I was
able paste really long lines into the U-Boot console, without any
characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support"

2017-08-24T03:00:47+00:00

This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881.

As Bin Meng has tested and pointed out, we don't need the RX interrupt
for the RX buffer support at all. Just reading all available characters
into a buffer is sufficient to solve the problem with the dropped
characters upon long lines pasted into the U-Boot prompt. Since this
RX buffer support can be implemented in a generic way, without any
device specifica (e.g. for the ns16550), I'll post a new patch with
a new serial RX buffer support for DM, which all DM based serial
drivers can use.
