- removed C0.C access when result is not used in

- access C0.C only once per target, store result
in cp15_cache_info field of target structure
- fix cache index count calculation
Global variables 'dc' 'ic' had been used in the code
to keep target's state of D-cache and I-cache
on debug entry.
This may lead to incorrect operation in configurations
with multiple cores and unequal cache states.
Fix: move cache state to the appropriate bits of the

flash: stm32f1x: Pad odd byte writes early to avoid 16-bit writes
For odd byte counts, stm32x_write() pads the last byte and writes it using
a discrete 16-bit access. The stlink debugger can't issue 16-bit writes so
it fails for odd byte writes.
This patch changes stm32x_write() to pad odd byte writes into a new buffer
and use the normal code path with a single block write. The fallback path,
when working area cannot be allocated, has to use 16-bit writes though
which means that sufficient working area is required for stlink and odd
byte writes.

Test the incoming debug_level, rather than the current.
The existing code tests the current debug_level for validity, allowing
the user to set it too high and never change it after that. The new
behaviour is to test the debug_level that the user has requested.
Based on ft2232.c but uses the MPSSE layer for low-level access, greatly
simplifying the JTAG logic. Remove all libftdi/FTD2XX code and all layout
specific code. Layout specifications are instead handled in Tcl.
Use a signal abstraction to enable Tcl configuration files to define
outputs for one or several FTDI GPIO. These outputs can then be
controlled using the ftdi_set_signal command. Special signal names are
reserved for nTRST, nSRST and LED (for blink) so that they, if defined,
will be used for their customary purpose.
Depending on the type of buffer attached to the FTDI GPIO, the outputs
have to be controlled differently. In order to support tristateable
signals such as nSRST, both a data GPIO and an output-enable GPIO can be
specified for each signal. The following output buffer configurations are
supported:
* Push-pull with one FTDI output as (non-)inverted data line
* Open drain with one FTDI output as (non-)inverted output-enable
* Tristate with one FTDI output as (non-)inverted data line and another
FTDI output as (non-)inverted output-enable
* Unbuffered, using the FTDI GPIO as a tristate output directly by
switching data and direction as necessary
The data and output-enables are specified as 16-bit bitmasks,
corresponding to the concatenation of the high and low FTDI GPIO
registers. To specify an unbuffered output, use the same bitmask
for both data and output-enable.
The adapter configuration file must also specify default values for the
FTDI data and direction GPIO registers, and the channel being used (if
different from 0).

Interface drivers regularly need to keep track of where each part of a long
read buffer should be copied, once that data arrives. Both source and
destination are often at an arbitrary bit offset.
This queued bit-level copy can help with that, by allowing the driver to
perform postponed reads from the receive buffer already when building the
transmit buffer, and have those reads executed at a later time when data is
available.
For simplicity, it uses the linked list implementation list.h imported from
the Linux kernel.
