* serial: serial-uclass: Add generic serial RX buffer supportStefan Roese2017-08-242-2/+61
| | | | | | | | | | | | | | | | | | 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"Stefan Roese2017-08-242-128/+5
| | | | | | | | | | | | | | | | | | | 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.

* x86: ich-spi: Move opcode registers configuration to another routineBin Meng2017-08-241-6/+16
| | | | | | | | | | | At present the ICH SPI opcode registers configuration is done in the ich_spi_remove() routine, a little bit weird but that's how current. Linux MTD driver works. This changes to move the opcode registers configuration to a separate routine ich_spi_config_opcode() which might be called by U-Boot itself as well.

* x86: ich-spi: Don't read cached lock statusBin Meng2017-08-242-8/+23
| | | | | | | | | | | | | | | | | | | At present the ICH SPI controller driver reads the controller lock status from its register in the probe routine and saves the lock status to a member of priv. Later the driver uses the cached status from priv to judge whether the controller setting is locked and do different setup. But such logic is only valid when there is only the SPI controller driver that touches the SPI hardware. In fact the lock status change can be trigged outside the driver, eg: during the fsp_notify() call when Intel FSP is used. This changes the driver to read the lock status every time when an SPI transfer is initiated instead of reading the cached one.
