* arm: Remove unused ST-Ericsson u8500 archStefan Roese2015-09-15-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This arch does not seem to be supported / used at all in the current U-Boot mainline source tree any more. So lets remove the core u8500 code and code that was only referenced by this platform. Please note that this patch also removes these config options: - CONFIG_PL011_SERIAL_RLCR - CONFIG_PL011_SERIAL_FLUSH_ON_INIT As they only seem to be referenced by u8500 based boards. Without any such board in the current code, these config option don't make sense any more. Lets remove them as well. If someone still wants to use this platform, then please send patches to re-enable support by adding at least one board that references this code.

It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

* dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial portHans de Goede2015-08-10-3/+28
| | | | | | | | | | | | | | | | | | | | 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.

Fix this by inlining the missing write to the baud control register. Also renaming the set_line_control() function to pl011_set_line_control() since this function is clearly PL011-specific, and it won't suffice to call that to set up line control.
