net: dm9k: Fix buswidth setting for platform data probe ...

priv->buswidth expects IORESOURCE_MEM_* macros which are not
identical to the integer byte bus width, so calling
dm9000_setup_buswidth() for the platform_data case is wrong.

mtd: nand: gpmi: Use subpage reads only on suitable NAND chips ...

On some NAND chips the driver uses a ECC size that is not dividable by
the number of chunks per page which means a single chunk cannot be read.
Disable the subpage feature for these NANDs. This is quite unfortunate
since the subpage feature really speeds up scanning NAND chips.

Commit da89ee8f2e04 ("Center FLP timing at 16ms") breaks
genphy_restart_aneg() for Micrel's ksz9031. According to the
datasheet, the ksz9031 requires a wait of 1ms after clearing
the PDOWN bit and before read/write access to any PHY registers.

e1000: Fix a bug in e1000_probe() ...

There are several reasons why that code in e1000_probe had to be
changed:

 - It reads from chip variant specific register (present only on
   i210) in a chip variant agnostic codepath

 - It makes no sense to check for FLUPD bit to make a decision weither
   to validate EEPROM or not since its function per datasheet is:

   " ... Flash Update.

     Writing 1b to this bit causes the content of the internal 4 KB
     shadow RAM to be written into one of the first two 4 KB sectors
     of the Flash device (Sector 0 or Sector 1). The bit is
     self-cleared immediately... "

   and it is only through sheer serendipity the defined value for
   bitmask for FLUPD is equivalent to bitmask for FLASH_DETECTED bit
   which is the bit we actually care about and need to test against
   (FLUPD for i210 has a different bitmask)

Fix those problems by replacing the i210 specific check inside of
e1000_validate_eeprom_checksum() with a chip agnostic one and using
correct bitmask.
