rockchip: serial: Kconfig: allow ROCKCHIP_SERIAL enabled in TPL

2022-04-18T03:25:13Z

The serial_rockchip.c driver converts platdata to the data structure used in the ns16550.c file and then calls the function ns16550_serial_probe(). When compiled with OF_REAL the serial_rockchip.c driver returns now -ENODEV when probed and does no harm. The config ROCKCHIP_SERIAL is currently depends on SPL_OF_PLATDATA. Allow serial port use for both SPL and TPL by removing this dependency and SPL_BUILD restriction. Signed-off-by: Johan Jonker Reviewed-by: Kever Yang

serial: Add semihosting driver

2022-04-01T19:03:13Z

This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: Add RISC-V HTIF console driver

2022-02-10T03:18:12Z

Quite a few RISC-V emulators and ISS (including Spike) have host transfer interface (HTIF) based console. This patch adds HTIF based console driver for RISC-V platforms which depends totally on DT node for HTIF register base address.

serial: Add a debug console using the RISC-V SBI interface

2021-10-07T08:08:23Z

The RISC-V SBI interface v0.1 provides a function for printing a character to the console. Even though SBI v0.1 functions are deprecated, the SBI console is quite useful for early debugging, because it works without any dcache, memory, or MMIO access in S mode.
