ee62ed3286 net: reduce boot latency on QE UEC based boards
actually polling for PHY autonegotiation to finish enables us to remove the
5 second boot prompt latency present on QE based boards.

call to qe_set_mii_clk_src in init_phy, and mv call to init_phy from
uec_initialize to uec_init by Joakim Tjernlund; autonegotiation wait
code shamelessly stolen from tsec driver.

also rm unused CONFIG_RMII_MODE code.

2465665b73 QE UEC: Extend number of supported UECs to 4
This patch extends the number of supported UECs to 4. Note that the
problem of QE thread resources exhaustion is resolved by setting the
correct number of QE threads according to Ethernet type (GBE or FE).

422b1a0160 Fix Ethernet init() return codes
Change return values of init() functions in all Ethernet drivers to conform
to the following:

    >=0: Success
    <0:  Failure

All drivers going forward should return 0 on success.  Current drivers that
return 1 on success were left as-is to minimize changes.

b8ec238503 85xx: add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

b96c83d4ae Fix numerous bugs in the 8568 UEC support
Actually, fixed a large bug in the UEC for *all* platforms.
How did this ever work?

uec_init() did not follow the spec for eth_init(), and returned
0 on success.  Switch it to return the link like tsec_init()
(and 0 on error)

The immap for the 8568 was defined based on MPC8568, rather than
CONFIG_MPC8568

CONFIG_QE was off

CONFIG_ETHPRIME was set to "Freescale GETH".  Now is "FSL UEC0"

Fixed a comment about the ranges for CONFIG_ETHPRIME if TSEC_ENET is
enabled

a28899c910 mpc83xx: Fix alternating tx error / tx buffer not ready bug in QE UEC
The problem is not gcc4 but the code itself. The BD_STATUS() macro can't
be used for busy-waiting since it strips the 'volatile' property from
the bd variable. gcc3 was working by pure luck.

This is a follow on patch to "Fix the UEC driver bug of QE"

ddd02492f4 mpc83xx: Fix the UEC driver bug of QE
The patch prevents the GCC tool chain from striping useful code for
optimization. It will make UEC ethernet driver workable, Otherwise the
UEC will fail in tx when you are using gcc4.x. but the driver can work
when using gcc3.4.3.

*Prevent the GCC from striping code for optimization, Otherwise the UEC
will tx failed when you are using gcc4.x.
