-LatticeMico32 target
---------------------
-
-General
--------
-All opcodes including the JUART CSRs are supported.
-
-
-JTAG UART
----------
-JTAG UART is routed to a serial console device. For the current boards it
-is the second one. Ie to enable it in the qemu virtual console window use
-the following command line parameters:
-  -serial vc -serial vc
-This will make serial0 (the lm32_uart) and serial1 (the JTAG UART)
-available as virtual consoles.
-
-
-Semihosting
------------
-Semihosting on this target is supported. Some system calls like read, write
-and exit are executed on the host if semihosting is enabled. See
-target/lm32-semi.c for all supported system calls. Emulation aware programs
-can use this mechanism to shut down the virtual machine and print to the
-host console. See the tcg tests for an example.
-
-
-Special instructions
---------------------
-The translation recognizes one special instruction to halt the cpu:
-  and r0, r0, r0
-On real hardware this instruction is a nop. It is not used by GCC and
-should (hopefully) not be used within hand-crafted assembly.
-Insert this instruction in your idle loop to reduce the cpu load on the
-host.
-
-
-Ignoring the MSB of the address bus
------------------------------------
-Some SoC ignores the MSB on the address bus. Thus creating a shadow memory
-area. As a general rule, 0x00000000-0x7fffffff is cached, whereas
-0x80000000-0xffffffff is not cached and used to access IO devices. This
-behaviour can be enabled with:
-  cpu_lm32_set_phys_msb_ignore(env, 1);
