Can't compile for ATmega640/1280/2560 with SD CS pin on PORTH or higher

This was trying to build for SD CS Arduino pin 8 but I get similar errors for any bit on any port above G.

I haven't had much luck searching for information on this. The best I've found is http://www.nongnu.org/avr-libc/user-manual/group__avr__sfr__notes.html but I've tried every combination of the fixes listed and still couldn't compile but I'm just basically working on it randomly since I don't really understand what the problem is.

From datasheet it might be a problem related to:

For I/O registers
located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instructions must be replaced with
instructions that allow access to extended I/O. Typically "LDS" and "STS" combined with "SBRS", "SBRC", "SBR",
and "CBR".

For example, yiou can put following code inside init_spi (in asmfunc.S):

lds r16,DDRH ; sbr r16,0x80 ; EN: output sts DDRH, r16 ;

and

lds r16,PORTH ; cbr r16,0x80 ; EN: output sts PORTH, r16 ;

note that this example is for pin enable on H.7

Thanks @anatom74! I'm caught up in other projects right now but I am definitely planning to try to resolve some issues and make some improvements to avr_boot at some point in the future. Of course if someone gets around to doing it before me I surely don't mind!
