serial: stm32x7: add STM32H7 support

2017-09-22T11:40:01Z

STM32F7 and STM32H7 shares the same UART block, add STM32H7 compatible string. Signed-off-by: Patrice Chotard Reviewed-by: Simon Glass

serial: nulldev: Add nulldev serial driver

2017-09-13T13:24:24Z

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. Signed-off-by: Joe Hershberger Signed-off-by: Keng Soon Cheah Cc: Chen Yee Chew

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

2017-08-24T03:00:47Z

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"

2017-08-24T03:00:47Z

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.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24Z

We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also. Suggested-by: Wolfgang Denk Signed-off-by: Simon Glass

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

2017-08-02T19:26:25Z

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. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu Signed-off-by: Nobuhiro Iwamatsu

serial: sh: Convert to Kconfig

Convert the SH Serial to Kconfig using tools/moveconfig.py tool and a bit of manual adjustment to cater for failed conversions. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu Signed-off-by: Nobuhiro Iwamatsu

dm: console: Check for serial devices properly

2017-07-31T16:21:40Z

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. Signed-off-by: Simon Glass

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

2017-07-27T12:59:03Z

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.
