/*
* spminterface.h offers a lightweight interface by inserting
* an small machine-subroutine into the bootsection. (right
* after the interrupt-vector-table)
* This subroutine can be called by normal code in order to
* enable it to program the flash (and depending on BLB11-lockbit
* also the bootsection itself). Since SPM-calls from RWW-sections
* will fail to work. The routine will be called "bootloader__do_spm".
* Its principle assembler-code is depicted below (real code is a
* little machinedependend).
* Interfaces will be the 8-bit registers r10..r13, for details
* also see below. As also the pageaddress-registes (Z and rampZ)
* are interfaced via different registers, it is possible to call
* this routine via indirect call (icall).
* Traditionally it is also possible to rcall, therefore you can
* define "bootloader__do_spm" for your normal code via defsym at
* linking time.
* Example for an atmega8: "-Wl,--defsym=transfer_point=0x1826"
* (since BOOTLOADER_ADDRESS is 0x1800 and there are
* 2x19 = 38 = 0x26 byte for interrupts)
*
