Omair Javaid 2830008be0 Support for AArch32 SIMD/Floating-point registers
This patch adds support for read/write of SIMD and floating-point register in AArch32 mode.
This patch is tested using Raspberry Pi3 halted in AArch32 mode with FP/SIMD enabled.
Software need to make sure floating-point and SIMD unit is enabled.

Omair Javaid a48264414e Support AArch64 SIMD/FP registers read/write
This patch adds support in openOCD to read/write AArch64 SIMD/FP registers.
This patch depends on a previous patch which adds support to generation 
of target xml by openOCD with nested architecture defined types. AArch64 
SIMD/FP registers assumes various types and to support all types we 
implement them as architecture defined type aarch64v which in turn 
consists of various architecture defined types. This is compatible with 
AArch64-FPU target xml in GDB. Please refer to 
binutils-gdb/gdb/features/aarch64-fpu.xml

Omair Javaid b4a01f8cdc Allow generation of nested target defined types in gdb target xml
This patch adds support to generate multiple nested architecture defined
data types in gdb target xml generated by openOCD. Architecture defined 
structs, unions, vectors nested in one or more architecture defined 
types can be generated now.

Example:

  <vector id="v2d" type="ieee_double" count="2"/>
  <vector id="v2u" type="uint64" count="2"/>
  <vector id="v2i" type="int64" count="2"/>

  <union id="vnd">
    <field name="f" type="v2d"/>
    <field name="u" type="v2u"/>
    <field name="s" type="v2i"/>
  </union>

Tomas Vanek bb9d9c6026 target: use correct target in target-prefixed commands and event handlers
This change contains an alternative to Matthias Welwarsky's #4130
(target-prefixed commands) and to #4293 (event handlers).

get_current_target() must retrieve the target associated to the current
command. If no target associated, the current target of the command
context is used as a fallback.

Many Tcl event handlers work with the current target as if it were
the target issuing the event.

current_target in command_context is a number and has to be converted
to a pointer in every get_current_target() call.

The solution:
- Replace current_target in command_context by a target pointer
- Add another target pointer current_target_override
- get_current_target() returns current_target_override if set, otherwise
	current_target
- Save, set and restore current_target_override to the current prefix
	in run_command()
- Save, set and restore current_target_override to the event invoking
	target in target_handle_event()

While on it use calloc when allocating a new command_context.

Tim Newsome 10108b623d Add `authdata_read` and `authdata_write` commands.
They can be used to authenticate to a Debug Module.

There's a bit of a chicken and egg problem here, because the RISCV
commands aren't available until the target is initialized, but
initialization involves examine(), which can't interact with the target
until authentication has happened. So to use this you run `init`, which
will print out an error, and then run the `riscv authdata_read` and
`riscv authdata_write` commands. When authdata_write() notices that the
authenticated bit went high, it will call examine() again.

Example usage (very simple challenge-response protocol):
```
init

set challenge [ocd_riscv authdata_read]
riscv authdata_write [expr $challenge + 1]

reset halt
```

Matthias Welwarsky b551c62a7f cortex_a: fix handling of Thumb-2 32bit breakpoints
When debugging Thumb-2 code, Gdb will at times send a
breakpoint packet 'Z0,<addr>,3', the number 3 denoting that
the instruction to break on is 32 bits long. Handle this by
replacing it with two consecutive 16bit Thumb BKPTs and make
sure to save and restore the full, original 32bit
instruction.

Note that this fix is only applicable if you debug a bare-metal program
(like the linux kernel) with the 'wrong' gdb, e.g. use an 
"arm-linux" gdb instead of an "arm-eabi" gdb. But since most people
may not know about the subtle differences between gdb configurations
regarding thumb2 breakpoints it's still valid.

Jonas Norling 6d390e1b2a efm32: Refactor EFM32 chip family data, add more chips
Add support for more EFM32/EFR32 Series 1 families. The family IDs
come from the DEVICE_FAMILY list in the EFM32GG11 reference manual,
which is the most up to date source I could find. Register locations
have been checked against SiLab's header files.

No datasheets or headers were available for EFR32MG2, EFR32xG14 and
EFM32TG11B, so they are just assumed to follow the pattern. EFM32GG11B
has the MSC registers on a different address compared to other chips.

This commit attempts not to change current behavior when detecting
chips. One detail that has changed is that PAGE_SIZE is read before
applying the workaround for old Giant and Leopard Gecko revisions, but
this is believed to be OK because the register exists but just has an
invalid value in it.

The manuals disagree on which of 120 and 121 is WG, so this commit
leaves it as is.

Tim Newsome 64f1f7b1c1 Add read buffer to bitbang, improving performance.
Previously for every bit scanned OpenOCD would write the bit, wait for
that bit to be scanned, and then read the result. This involves at least
2 context switches. Most of the time the next bit scanned does not
depend on the last bit we read, so with a buffer we now write a bunch of
bits to be scanned all at once, and then we wait for them all to be
scanned and have a result.

This reduces the time for one testcase where OpenOCD connects to a
simulator from 12.30s to 5.35s!

Running all our tests went from 13m13s to 3m55s.

Tomas Vanek e3f3b77729 flash Kinetis: make FCF protection more user friendly
The Flash Configuration Field on Kinetis devices requires protection
because it is located in program flash space (at 0x400) and writing
an improper data to it may permanently lock the device. Even an erased
flash sector containing FCF engages security lock (not permanent one)
on the next reset or power cycle.

'kinetis fcf_source protection' mode was introduced in the change #3562.
Flash driver in this mode sets FCF immediately after sector erase to
prevent unintentional security lock. To do so the driver needs to know
FCF values before flash image data is actually processed. Flash
protection bits are available in bank structure, FOPT can be set by
'kinetis fopt' command and securing device by FSEC is not supported.

Nevertheless an inexperienced user flashed the device using an image
with FCF values different from those set in OpenOCD config and
concluded programming did not work as some verify errors showed.

This change tries to write maximum possible from image data
retaining FCF protection.

Check FCF in programmed data and report if some field differs from
values set by OpenOCD flash block protection and 'kinetis fopt' command.
Warn user about verify errors caused by FCF protection.

On devices with ECC flash (K26, K66 and KV5x) it is impossible to change
already programmed FCF - it would result in an ECC error. As FCF was
written just after erase in 'kinetis fcf_source protection' mode
the warning issued during flash write is the only possible action.

On non-ECC flash devices use cumulative flash programming to
set FCF values requested in programmed image data.
Use FSEC from programmed data only if it does not request a secure
mode. Device can be secured only in 'kinetis fcf_source write' mode.
Use FOPT from programmed data if its value was not configured
in OpenOCD config by 'kinetis fopt' command.
