include/flash.h was commented to say that the address in flash_info->start was a physical address. However, from u-boot's point of view, and looking at most flash code, it makes more sense for this to be a virtual address. So I corrected the comment to indicate that this was a virtual address. The only flash driver that was actually treating the address as physical was the mtd/cfi_flash driver. However, this code was using it inconsistently as it actually directly dereferenced the "start" element, while it used map_physmem to get a virtual address in other places. I changed this driver so that the code which initializes the info->start field calls map_physmem to get a virtual address, eliminating the need for further map_physmem calls. The code is now consistent. The *only* place a physical address should be used is when defining the flash banks list that is used to initialize the flash_info struct, usually found in the board config file.
