Merge branch 'tg3'

Nithin Nayak says:

====================
For the 57766 devices with no NVRAM, there is not enough space for the complete
boot code with EEE support. On these devices, the tg3 driver has to download
a service patch firmware to the scratchpad for the boot code to execute. This
patchset adds support to do the above.

A major portion of this patchset is refactoring the existing firmware download
section to allow a cleaner merge of the 57766 download. The 57766 firmware
differs from previous firmware in that it's not written to a contiguous area in
memory. It consists of multiple fragments to be written to different locations.
The patchset makes an attempt to make the new firmware format to be an
extension of the existing format.
