The number if longwords or "sections" (Freescale term) written for a Kinetis
flash write (4, 8, or 16 bytes depending on the part density/granularity) are
now rounded up to ensure there are no truncations when the desired write is
not a multiple of the minimum write size.
Always scan out all bits, but make sure only the allowed number of bytes
end up in the caller-provided buffer. Discard the rest by adding another
scan field when size < 4.
Rewrite the endianness callback to avoid reading outside allocated memory.
Make it directly usable as a callback without the need for a wrapper. Move
the shared callback to a more suitable home in arm7_9_common.

Severe bug in Pracc code
The function wait_for_pracc_rw() fails if Pracc bit is 0.
The variable ejtag_ctrl is loaded with the content of the
control register in the first scan.
In the second scan Pracc bit is scanned out as 0, letting
the proccesor go. The result is unpredictable.
All the strange data corruption when scanning at certain
frequencies, or the strange delays needed when entering
or leaving fasdata area are retated to this bug.

and indepently of processor speed, tested at 31.25Khz and 4/8Mhz.

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.
