Alexander Osipenko 9c9c06b8ae arm946e: don't use global variables for context
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
'cp15_control_reg' field (already present but unused).
Vaule of cp15 control register stored here on
arm946e_post_debug_entry(), and analyzed later
in arm946e_write_memory().

Salvador Arroyo 5e1f5f4731 Bugfixes in mips32_pracc.c
When testing a pic32mx220f032b with different values
for adapter_khz and cpu clocks i was getting a lot of
corrupted data from the chip. From time to time
openocd fails with segmentation faults or is aborted
due to memory corruption.

Salvador 09cd5661e6 Speed up mips_m4k_write_memory()
Do not call mips32_cp0_read() if not needed.
This will speed up execution of mips_m4k_write_memory()
by near 2x, with parameter count = 1.

 - Renamed a few variables to improve readability:

 - Added a new variable, named byte to contain the number of bytes to read, instead
of overwriting the count parameter, to avoid confusion between the two values.

Spencer Oliver 7d1f9bafc7 target: remove unused declaration
arm7_9_prepare_reset_halt is long since gone and the functionality
is implemented in the target's assert_reset handler.

Øyvind Harboe ed12a6521f flash: retire unused eCos flash driver
even the AT91EB40a's flash is covered by CFI and nobody ever submitted
any other drivers based on eCos code. It's just possible that this
idea was missing documentation and "marketing", but it's in git if
somebody wants to resurrect it.

Spencer Oliver bee7184ce4 target: add target async algorithm support
Currently the stm32f1x flash driver uses an asynchronous algorithm
as part of the block flash programming. This greatly speeds up flash
programming as the target is always running.

Moving the async code to the target enable other targets to use this
added functionality.

Andreas Fritiofson 2eb564b756 target: add function to get number of bytes available in working area
This is a much cleaner solution to the problem of allocating as much
working area as possible than what is currently being done in most/all flash
drivers (which is: try an arbitrary sized chunk, if it fails, pick a smaller
number, rinse and repeat).

Use this function to find out how much working area is available, limit or
restrict that amount at will and then simply allocate it.

Andreas Fritiofson 813f4a5411 target: rewrite working area allocator
The existing allocator couldn't reuse a freed allocation if the sizes
didn't match exactly. That led to problems when for example a flash write
routine had allocated all of the working area to speed up operation. A
subsequent verify pass couldn't allocate space for the checksum algorithm
even though all previous allocations had been freed.

This allocator is marginally more complex, but solves the above problem by
splitting larger free areas to fulfill smaller requests and by merging
released areas into adjacent free areas.

An initial free area, covering the entire specified address range, is set
up on first allocation, and all allocations are split off from (and
ultimately merged into) that one. It can also easily be adapted to support
several disjoint working areas for the same target, by setting up several
initial free areas and slightly modifying the merge code.
