Hello

The patch provides support for the NXP IAP (In Application Program)
interface. I just want to reserve this support to do not duplicate IAP
code in lpc2xxx on-chip flash drivers. flash_lpc2xxx_v2 comming soon.
Hans's Rosenfeld legacy flash_arm_lp2xxx driver uses IAP. The future V2
driver will use it too. I though that Hans's driver can be cleaned up
then when IAP interface will be included in CVS.

I saw no such a support in other HALs. And I decided to put it under the
lpc2xxx/var tree. 

RFC: Is it a good place for the interface in lpc2xxx/var?

There is a small test case there. The new API was tested on Olimex
LPC2294 header board

(gdb) cont
Continuing.

Kind regards,

Sergei
