2012-04-03net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall backEric Miao
Ignore the return value of eth_getenv_enetaddr_by_index(), and if it fails, fall back to use dev->enetaddr, which could be filled up by the ethernet device driver: With the current code, introduced with below commit, eth_write_hwaddr() will fail immediately if there is no eth<n>addr in the environment variables. However, e.g. for an overo based product that uses the SMSC911x ethernet chip (with the MAC address set via EEPROM connected to the SMSC911x chip), the MAC address is still OK. On mx28 boards that are depending on the OCOTP bits to set the MAC address (like the Denx m28 board), the OCOTP bits should be used instead of failing on the environment variables. Actually, this was the original behavior, and was later changed by commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.

2012-03-18bootstage: Plumb in bootstage calls for basic operationsSimon Glass

2012-03-18net/miiphy/serial: drop duplicate "NAMESIZE" defineMike Frysinger
A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-12-20net: introduce per device indexMichael Walle
Instead of counting the device index everytime a functions needs it, store it in the eth_device struct. eth_register() keeps track of the indices and updates the device's index number. This simplifies some functions in net/eth.c. Additionally, a network driver can now query its index, eg. to get the correct environment ethaddr name.

2011-12-06net: Make sure IPaddr_t is 32 bits in sizeMatthias Weisser
When building u-boot as 64 bit application (e.g. sandbox) ulong might be 64 bits in size. This breaks network code as IPaddr_t is 64 bytes in size then and an IPv4 address is 32 bits in size. This patch makes sure that IPaddr_t is always 32 bits in size. Also some warnings introduced by this patch are fixed.
