This builds and boots. Because of the function pointer indirection (e.g. mtd_info's read function pointer is assigned to spiflash_read), it is difficult for me to understand where the calls are coming from (could be anywhere, conditionally pointing at spiflash versions), so I punted and used the renamed function pointers (_erase, _read, _write). If someone knows better what to do, please fix. Cleaned up other sundry kernel tracking issues like get_phy_id and __devinit,etc. [juhosg: don't switch to that yet] Signed-off-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 35727
