- update to new relocation code
- switch to boards.cfg
- get rid of LEGACY (still a little hack in .h to compile)
- add nand boot configuration
- boot tested for the following configurations :
	9260 (64MB RAM & nor boot)
	9260_nand (64MB RAM & nand boot)
	9G20_128M (128MB RAM & nor boot)
	9G20_nand_128M (128MB RAM & nand boot)
	(nor boot is using lowlevel init)

Checkpatch warns about the volatile here.

I know the get_ram_size() prototype calls for the volatile attribute, 
but what is the rationale here for this? get_ram_size() just needs the 
RAM base address *value*; if it requires volatile accesses to it, it can 
arrange for these inside its definition. Besides, throughout the code 
base there are 19 instances of get_ram_size() callw where the argument 
is cast to volatile, against 130 where it is not.

Wolfgang et al.: how about removing the 'volatile' qualifier from the 
get_ram_size() prototype?

Eric: if your patch does not cause a warning without the volatile in the 
call, can you update and repost it as V2?

Checkpatch considers these errors. This is again a case where we'd want 
it to ignore it... or reconsider this type of macro, which intends to 
expand to several function arguments.

For now I'll ignore these 6 checkpatch errors.

Amicalement,
