2018-01-29serial: Make full device search optionalAlexander Graf
Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails") added code to search for more serial devices if the default one was not probed correctly. Unfortunately, that breaks omap3_evm. So while investigating why that is the case, let's disable the full search for everyone but bcm283x where it is needed.

2018-01-28bcm2835_pl011_serial: Add BCM2835 specific serial driverAlexander Graf
On bcm2835 we need to ensure we only access serial devices that are muxed to the serial output pins of the pin header. To achieve this for the pl011 device, add a bcm2835 specific pl011 wrapper device that does this check but otherwise behaves like a pl011 device. Signed-off-by: Alexander Graf <agraf@suse.de>

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.

2017-08-24serial: serial-uclass: Add generic serial RX buffer supportStefan Roese
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.

2017-08-24Revert "serial: ns16550: Add RX interrupt buffer support"Stefan Roese
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.
