9bf499ace8 powerpc/T4240QDS/eth: some fix for XFI
XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs
of serdes2 are routed to a SFP+ cages, which to house fiber cable or
direct attach cable(copper), the copper cable is used to emulate the
10GBASE-KR scenario.

So, for XFI usage, there are two scenarios, one will use fiber cable,
another will use copper cable. For fiber cable, there is NO PHY, while
for copper cable, we need to use internal PHY which exist in Serdes to
do auto-negotiation and link training, which implemented in kernel.
We use hwconfig to define cable type for XFI, and fixup dtb based on the
cable type.

For copper cable, set below env in hwconfig:

fsl_10gkr_copper:<10g_mac_name>

the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The
four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports,
if a given 10G port will use the copper cable for 10GBASE-KR, set the
<10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be
assumed to be used for the port.

For ex. if four XFI ports will both use copper cable, the hwconfig
should contain:

fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2

For fiber cable:

1. give PHY address to a XFI port, otherwise, the XFI ports will not be
available in U-boot, there is no PHY physically for XFI when using fiber
cable, this is just to make U-boot happy and we can use the XFI ports
in U-boot.
2. fixup dtb to use fixed-link in case of fiber cable which has no PHY.
Kernel requests that a MAC must have a PHY or fixed-link.

When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface.

Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56
is not valid any longer.

94752f60eb powerpc/t4qds: Add alternate serdes protocols to align with A-007186
A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to
increase and cause the PLL to unlock when the temperature delta from the
time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V
(or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC
VCO. Only the protocols using Ring VCOs are impacted.

Workaround:
For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need
to use alternate serdes protocols. The alternate option has the same
functionality as the original option; the only difference being LC VCO
rather than Ring VCO.

037e19b812 powerpc/t4240qds: fix PHY reset timeout issue
QSGMII card has different PHY address against previous SGMII card.
We check the type of card in slots and set correct PHY address to
avoid complainning "PHY reset timed out" during u-boot booting up.

f63d638dad T4240/eth: fix SGMII card PHY address
QSGMII card assumed to be used by default, but if SGMII card is used,
it will use different PHY address, but we don't know which card is used
until we access PHY on the card. So we check the card type slot by slot,
if we can read a PHY ID by reading a SGMII PHY address on a slot, then
the slot must have a SGMII card pluged, we mark all ports on that slot,
and fix dts to use the SGMII card PHY address when doing dts fixup
for the marked ports.

959278083d t4240qds/eth: fixup ethernet for t4240qds
1, Implemented board_ft_fman_fixup_port() to fix port for kernel.
2, Implemented fdt_fixup_board_enet() to fix node status of different
   slots and interfaces.
3, Adding detection of slot present for XGMII interface.
4, There is no PHY for XFI, so removed related phy address settings.

The second slot has only 2 chip selects to support single- and dual-rank
DIMMs. At any given time, up to total 4 chip selects can be used.
