* Ignored RPCERRORs from the UMNTALL RPC call after an NFS transaction. Not all nfs servers implement this and it should not invalidate the file transfer since it is just for state tracking on the server. | * Ignored RPCERRORs from the UMNTALL RPC call after an NFS transaction.

* Fixed USB 5V reset timing for boards with hubs. USB 5V is now disabled 500ms after OFF_BD_RESET is disabled. On older revs USB may not detect some peripherals if the USB 5V comes up before the hub is out of reset. | |||
* Added "rcause" variable. This lets u-boot scripts make use of the reset cause in scripts. For example, if rcause is "POR" in the field, it may have experienced a brownout and an alternate kernel/os could be booted instead. If rcause is "WDOG" then either a reset or watchdog condition caused the reset. | |||
* New "model" variable with "4900" or "7970", etc. This is so common usb blasters can be used and determine the model. | |||
* new "rev" variable including "A" or "C". This is also now printed at startup. | |||

* Included updates for REV C boards | |||
** If I2C locks up, reset RTC FET for rare lockup. | |||
* U-boot networking speed limited to 100Mb/s by default. Gigabit requires about 5 seconds to autonegotiate. 10/100Mb/s requires ~500ms. The common case being NFS booting which requires a 3-4MB kernel, 300kb of device tree, 100kb of fpga binary, gigabit only slows down booting. This does not disable gigabit for Linux. | |||
