Thank you for update.

Now that we have it working, let's prepare it for commit:

1. We don't want CYGNUM_DEVS_KINETIS_FLASH_LOGIC_ERROR_BUG work-around to ruin
the FLASH performance in normal operation, therefore it should be applied only
during the critical sections (write, erase, etc.). You can write inline
functions/macros that enable/disable it and call them where necessary.

2. Some protection of flash configuration area 0x400-0x40f. Let's think about
it.

3. Automatic block size determination. The default value should be derived from
the part type if possible. Also, the flash init function should check this
value against the real silicon (based on part Id, etc).

Should you may additional questions/comments esp. on 2. and 3. feel free to
ask.

Ilija
