Hello,

this series cleans up XTFPGA xtensa boards: reworks built-in mini
bootloader so that it supports warm reboots and makes function/structure
naming consistent in the hw/xtensa/xtfpga.c.
It extracts common local memory instantiation function into a separate
source file.
It adds noMMU variant for each XTFPGA board. noMMU XTFPGA variants have
different physical memory layout: the RAM size is limited to 256M and
it starts at physical address 0x60000000 and MMIO is visible through two
ranges of physical addresses starting at 0x70000000 and 0x90000000.
The series imports two noMMU cores: de212 (noMMU default core for xtensa
linux) and sample_controller (default core for xtensa Zephyr OS).
