- Import various DT files for DRA7 / DR72x / dra72-evm from Linux Kernel v4.1 - Add config file for this board, enable DM and DM_GPIO Cc: Simon Glass Signed-off-by: Tom Rini Reviewed-by: Simon Glass

drivers: hierarchize drivers Kconfig menu

2015-08-13T00:47:44Z

The menuconfig for drivers are getting more and more cluttered and unreadable because too many entries are displayed in a single flat menu. Use hierarchic menu for each category.

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port

2015-08-10T13:01:28Z

Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

exynos: Enable the debug UART in SPL

2015-08-06T03:06:11Z

As a debugging aid, allow UART3 to be used as a debug UART in SPL. This is a precursor to proper UART support, which requires a substantial refactor. Signed-off-by: Simon Glass

exynos: Add debug UART support for Samsung S5P serial

2015-08-06T03:06:11Z

Add a debug UART implementation for this serial driver. It does not set up pinmux automatically - this must be done before calling debug_uart_init(). Signed-off-by: Simon Glass

exynos: serial: Refactor init code for debug UART

2015-08-06T03:06:11Z

The debug UART code needs to perform the same init as the normal UART driver. In preparation for this, move the init code into two functions, one for the basic init and one for setting the baud rate. This will make adding debug UART support easier. Signed-off-by: Simon Glass

dm: serial: Correct logic in serial_find_console_or_panic()

2015-08-05T14:42:40Z

In a final attempt to find a console UART this function uses the first first available serial device. However the check for a valid device is inverted. This code is only executed when there is in fact no serial UART, but at present it can fail to reach the panic_str() call in this case, and start trying to use a non-existent UART.

ns16550: Improve debug UART so it can work with 32-bit access

Since Rockchip requires 32-bit serial access, add this to the driver. Refactor a little to make this easier. Signed-off-by: Simon Glass
