Currently the code is loaded calling mips32_pracc_write_mem_generic().
Cache synchronization is not performed.
If configured as write back cache there is no chance to execute the
handler. If configured as write through cache and the cache
lines written to are not cache resident (I-side cache miss) may work.
The patch makes possible to execute the handler in a cached active
memory segment (mainly from KSEG0), but nothing else. The data
is still loaded without performing cache synchronization, code loaded
may not be executable.
Performance may not be faster. At start, for example, the code resides in
main memory, not in cache, and the core must transfer code from
memory. We can really modify the code to force a wait for the first
transfer like we do with start and end addresses, making sure the code
is cache resident for the rest of the queued transfers.
This can also may happen if we execute code (greater than the I cache size)
and the handler code is evicted from the cache.
Code tested on ar7241.

Currently the functions mips32_checksum_memory() and mips32_blank_check_memory()
load the code word by word.
The bug in cache code is a good reason for doing so.
If there is no other reason we can load the code as a buffer to save time.
mips_m4k_write_memory() expect a buffer in target endianness, this is done by
target_buffer_set_u32_array().
Cleaned up exit code.
Tested on ar7241 big endian and pic32mx little endian with verify_image.
Flash erase check only tested in pic32mx.

The TI TMS470 and TMS570 series of processors are BE-32 processors,
despite BE-32 not being supported by ARM in the Cortex-R4 core. TI
hacked in BE-32 support, which requires odd swizzling in OpenOCD to
make memory reads and writes function correctly. In particular,
without this change, OpenOCD word reads and writes had the bytes
reversed, and halfword and byte packed reads were reading garbage.
In my testing, this change fixes these problems.

Some fixes to 'samd_protect' including:
- Fix a bug in which the value of 'set' parameter passed into the
function was ignored so it was impossible to remove flash
protection once it was set.
- Check the protection status of the sector via 'is_protected'
field of the corresponding 'flash_sector' structure to see if
any actual HW manipulations needs to be done.
- Change the way the errors during protection activation are
handled. Now even in the case of error in the middle of
protecting a number of sectors the subroutine would still update
the state of the sector protection in sectors array so as to
avoid cases where openocd thinks that the sector is not protected
while it actually is.

This introduces a new global Tcl procedure that is run just after
init_targets and before init_boards.
Its default behaviour is to assign gdb-flash-erase-start and
gdb-flash-write-end to reasonable defaults.
The rationale for doing "reset init" before gdb erases and flashes
memory is that all flash drivers are written in assumption that they
can safely be used only after chip reset (plus chip-specific
configuration in the init handler if any). The need to use "reset
halt" after flashing is because a user expects running firmware after
loading to be the same as running it from power-on-reset.
