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 This will most likely be superceded by a proper driver after the port has matured.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>

soc: esp32: Define __start as a C function The first stage bootloader, part of the ESP32 ROM, already sets up a stack that's sufficient to execute C programs. So, instead of implementing __stack() in assembly, do it in C to simplify things slightly. This ESP32-specific initialization will perform the following: - Disable the watchdog timer that's enabled by the bootloader - Move exception handlers to IRAM - Disable normal interrupts - Disable the second CPU - Zero out the BSS segment Things that might be performed in the future include setting up the CPU frequency, memory protection regions, and enabling the flash cache.
