On operating systems with opportunistic malloc() (e.g. default setting in
GNU/Linux) malloc can sometimes allocate a huge memory region but later the
process will get killed on the first attempt to use this memory, so
checking for malloc's return value is not enough to prevent a crash.
This patch is compile-tested only.

When gdb loads an elf file of a newer or older version of the firmware
being debugged, or when the firmware is not running yet, there's a high
probability of FreeRTOS variables to be read incorrectly, thus leading to
an attempt to allocate an enourmous amount of memory. Without this check
OpenOCD simply crashes and that's mad confusing.

Atmel introduced 7 new Cortex-M3 processors on 2012-02-28
SAM3X4C - 256KB flash
SAM3X4E - 256KB flash
SAM3X8C - 512KB flash
SAM3X8E - 512KB flash
SAM3X8H (Only on dev-kit - not in production...) - 512KB flash
SAM3A4C - 256KB flash
SAM3A8C - 256KB flash
The SAM3X/A processors still suffer from the "6 waitstates needed
to program device" errata.
The CIDR address for the SAM3X/A processors are different from the
other SAM3 processors. Unfortunately, the chip identification register
is not at a constant address across all of the SAM3 series'. As a
consequence, a simple heuristic is used to find where it's
at... If the contents at the first address is zero, then we know
that the second address is where the chip id register is.
We can deduce this because for those SAM's that have the chip id @ 0x400e0940,
the first address, 0x400e0740, is located in the memory map of the Power
Management Controller (PMC). Furthermore, the address is not used by the PMC.
So when read, the memory controller returns zero.
Another interesting change is the flash bank address for flash bank 1.
It is not fixed at 0x00100000 like the Sam3U. Bank 1 of the at91sam3a/x
series starts at 0x00080000 + half the total flash size. Thus for the 256KB
devices Bank 1 is located at 0x000A0000, and for the 512KB devices Bank 1 is
located at 0x000C0000.
The configuration files for the SAM3X/A processors will follow

This is a much cleaner solution to the problem of allocating as much

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.

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.
