Add memory config for STM32F4

[vmayoral]

The previous memory map didn't allow to debug the whole flash
memory while working with the STM32F4Discovery. A new
configuration has been added and should be used while working
with the STM32F4Discovery board.

Refer to ros2/ros2_embedded_nuttx#7.

If the memory map needs to be updated, could you please update the original map, rather than adding a new one and commenting out use of the original?

Thanks for the patch, but I will wait before applying it. Can you do as
Michael
suggests ?

Done. Let me know if you guys need something else.

Taking a look at Table 5 in RM0090 (STM32F4 Reference Manual, Flash module organization (STM32F40x and STM32F41x)), it looks like the length should actually be 0xE0000 to cover all sectors. Otherwise, LGTM.

A whole other issue is supporting the 2MB flash in STM32F42x/3x.

@prattmic thanks for the catch. I actually didn't notice the "length" keyword before the value. Having noticed that i agree, 0xE0000 should do it for the STM32F4Discovery.
