…shing large programs This fixes the builder for ESP32 (original) by separating the RAM segments loadable by the ROM bootloader from flash-mapped segments (DROM/IROM) which require MMU setup by startup code. These changes are needed for to allow for ESP32 to correctly flashing large programs which as a result require XIP support. Signed-off-by: deadprogram <ron@hybridgroup.com>

This PR has improvements for ESP32 to correctly flash large programs, which as a result requires XIP support.
This modifies the builder for ESP32 (original) by separating the RAM segments loadable by the ROM bootloader from flash-mapped segments (DROM/IROM) which require MMU setup by startup code.
Tested on ESP32 boards with some larger programs using upcoming espradio support for ESP32 classic.
