The Auto Negotiation procedure between two Ethernet PHYs consists of determining the best commonly supported parameters among Speed, Duplex Mode and Flow Control. The time taken for this procedure is not only dependent on the local PHY used, but also on the link-partner PHY. While a timeout can be specified in the form of a "CONFIG" on the basis of the local PHY present on the device, since the timeout also depends on the link-partner PHY, it might be necessary to modify the timeout. To avoid rebuilding the bootloader for a given device, just because it may be connected to various link-partner PHYs, each with a different timeout, introduce an environment variable named "phy_aneg_timeout" and override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
