the riscv-tools build script make a subdirectory to build in, other submodules ignore this file

Testsuite now passes on multicore target

Right now we're using "threads" to represent harts. gdb/OpenOCD assume
there's only one set of hardware breakpoints among all threads. Make it
so.

This ensures that "info threads" is accurate as soon as gdb connects.
Also print out number of triggers that is discovered in examine().

Various cosmetic improvements

Update debug_defines from the spec, commit 920ec9a690.
Decode dmstatus scans in the debug output.

Assuming the program allocating code works, we don't need its output.
Only output parts of the debug RAM that are actually doing something.

Fix indentation to match OpenOCD style.

This change is just in the whitespace. There are no code changes.

See http://openocd.org/doc-release/doxygen/stylec.html

Two fixes from the release branch

Fix print statements to work with 64-bit addresses

When I disappeared the polls everywhere I forgot to sanitize the hartid
after halting.  This is an invariant that GDB expects: when you return
from a halt whatever thread is marked as currently selected is the
thread that the next register accesses reference.

Accept 64-bit addresses in CRC requests.

Merge mainline OpenOCD

Main change is to make riscv_addr_t be unsigned. The rest is mechanical
fixing of types, print statements, and a few signed/unsigned compares.

Smoketest indicates everything is working more or less as before.

Doesn't build yet, but I fixed the conflicts that git pointed out.

Fix dmi_read() indentation; remove \n in LOG_ERROR

When gcc isn't optimizing well, it might not realize that it's not
possible to return fd without initializing it, and then the build fails
due to -Werror.

Extended and revised version of my original patch submitted by Dmytro
here: http://openocd.zylin.com/#/c/3390



This driver is using pure SPI mode, so the flash base address is not
used except some flash commands (e.g. "flash program") need it to
distinguish the banks.

Example config with all 3 chip selects:
flash bank flash0 ath79 0 0 0 0 $_TARGETNAME cs0
flash bank flash1 ath79 0x10000000 0 0 0 $_TARGETNAME cs1
flash bank flash2 ath79 0x20000000 0 0 0 $_TARGETNAME cs2

Example usage:
> flash probe flash0
Found flash device 'win w25q128fv' (ID 0x001840ef)
flash 'ath79' found at 0x00000000
> flash probe flash1
No SPI flash found
> flash probe flash2
No SPI flash found
> flash banks
> flash read_bank flash0 /tmp/test.bin 0x00000000 0x1000
reading 4096 bytes from flash @0x00000000
wrote 4096 bytes to file /tmp/test.bin from flash bank 0 at offset
0x00000000 in 28.688066s (0.139 KiB/s)

For some targets (like nrf51) sysfs driver is too slow. This
patch implements memory maped driver for IMX processors.
Mostly based on bcm2835gpio. Tested on imx6ul CPU. However, it should
work on any NXP IMX CPU.

GDB seems to just go off the rails if I return a SIGINT.

I missed this event.  It appears to do nothing.

This means I don't know what hart to look at, so I might as well
invalidate the register cache.  Without this, you might get stale
registers the first time you ask for them.

I thought OpenOCD did this, but it looks like that doesn't happen when
runningi in RTOS mode.  With this I can get to the end of most of the
RTOS tests, but they SIGINT instead of exiting.

riscv-v11: Don't perform unexpected operation in cache_write

This fixes a race condition when reading/writing memory.
