Inaky Perez-Gonzalez	271c518ec6	uart_esp32: alter the uart.h include order to avoid warning ... The esp-idf package contains on the BSP a definition of the BIT macro unconditionally #defined when rom/uart.h is #included. When Zephyr's uart.h (which pulls in include/misc/util.h) that conditionally This generates a compile warning on the re-definiton of BIT by the esp-idf package. Thus include uart.h after esp-idf's rom/uart.h to have BIT not re-defined thanks to Zephyr's conditional definition.

Leandro Pereira	37ea77173c	drivers: esp32: Add minimal UART driver based on ROM routines ... This is a minimal driver enabling console output during the port bringup. While the driver works, only one of the three UART devices are supported, and there isn't any way to change any parameters or use interrupts. This will most likely be superceded by a proper driver after the port has matured. Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>	2017-06-21 12:35:49 -04:00
