Fix Flash Implementation for new Hardware Iteration

[DavidFederl]

The new hardware Iteration features a larger flash with 256MB. This shouldn't be a problem, but the sector and page size has also changed!

We now have only 64KiB sectors instead of 256KiB and the page size is reduced from 512B to 256B.

The implementation has to catch this stuff. We Should provide this inside a config file instead of the actual flash library.
The flash library should then only check if the FLASH_BYTES_PER_PAGE and FLASH_BYES_PER_SECTOR are defined and if not exit with error.

Maybe we should use the ICF read to properly setup the library without requiring user input.

Maybe we should use the ICF read to properly setup the library without requiring user input.

This can be accomplished by passing a configuration (struct) to each function call which holds all required values. Values like

• Page Size
• Sector Size
• Total Memory

Can best set inside the flashInit(...) function. Whereas values like

• SPI module
• GPIOs

Should be set by the user.
