5536aeb09b powerpc/eeprom: update MAX_NUM_PORTS to adapt non-256-bytes EEPROM
Some boards use System EEPROM with 128-bytes instead of 256-bytes.
Since we regard 256-bytes EEPROM as standard EEPROM with default
value for MAX_NUM_PORTS. For those non-256-bytes EEPROM, we can
redefine MAX_NUM_PORTS in board-specific file to override the
default MAX_NUM_PORTS.

This patch doesn't impact on previous existing boards.

ref_clock which is changed from 66.67MHz to 133.33MHz. so the ratio need to

ffee1dde3c SGMII:fix PHY addresses for QSGMII Riser Card working in SGMII mode
Fix PHY addresses for QSGMII Riser Card working in
SGMII mode on board P3041/P5020/P4080/P5040/B4860.

QSGMII Riser Card can work in SGMII mode, but
having the different PHY addresses.
So the following steps should be done:
	1. Confirm whether QSGMII Riser Card is used.
	2. If yes, set the proper PHY address.
Generally, the function is_qsgmii_riser_card() is
for step 1, and set_sgmii_phy() for step 2.

However, there are still some special situations,
take P5040 and B4860 as examples, the PHY addresses
need to be changed when serdes protocol is changed,
so it is necessary to confirm the protocol before
setting PHY addresses.

So it is not proper to organize SGMII5/6 and SGMII7/8
on one bus and SGMII5/6 can't work.
So a new bus SUPER_HYDRA_FM3_SGMII_MDIO is added for
SGMII5/6

1) Add support in B4860 board files for using IDT driver where

   that generate different refclks for SerDes modules, used this driver
   for reconfiguring SerDes1 Refclks(based on SerDes1 protocols)
   for CPRI to work. CPRI works on 122.88MHz and default refclks coming
   on board are not suitable for it
2) Move SerDes1 refclk1 source selection from eth_b4860qds.c file
   to b4860qds board file, as SerDes1 Refclk1 would come from
   PHY MUX in case of certain protocols, that have been checked here.
   This change would make on board SGMIIs to work
3) Add I2C addresses for IDT8T49N222A devices in board/include file
4) Add define for PCA-I2C bus multiplexer, on which IDT devices exist

45fdb627b3 p1020rdb-pd: platform support
Add new board p1020RDB-PD. P1020RDB-PD board was update from P1020RDB.
DDR changed from DDR2 1G to DDR3 2G.
NAND: 128 MiB
Flash: 64 MiB

Also change P1020RDB to P1020RDB-PC to distinguish from P1020RDB board.

c63e137014 powerpc/mpc8xxx: Add memory reset control
JEDEC spec requires the clocks to be stable before deasserting reset
signal for RDIMMs. Clocks start when any chip select is enabled and
clock control register is set. This patch also adds the interface to
toggle memory reset signal if needed by the boards.

5ecf41cc3d powerpc/t4240qds: Adjust DDR timing for RDIMM
RDIMM has different timing. Tested RDIMM is MT18JSF1G72PDZ-1G9E1 for
dual rank. Single- and quad-rank are not tested due to availability.

1cb19fbb31 powerpc/T4240EMU: Add T4240EMU target
Add emulator support for T4240. Emulator has limited peripherals and
interfaces. Difference between emulator and T4240QDS includes:
	ECC for DDR is disabled due the procedure to load images
	No board FPGA (QIXIS)
	NOR flash has 32-bit port for higher loading speed
	IFC and I2C timing don't really matter, so set them fast
	No ethernet
