e55782eccc powerpc/t4240qds: fix offset of serdes when checking reference clock
T4240 has 4 serdes, each serdes has 4k memory space, two PLLs.
We use PLL1CR0 to check the serdes reference clock.

9d0456822c powerpc/mpc85xx: Check return value of find_tlb_idx
find_tlb_idx() is called in board_early_init_r() on multiple boards.
The return value is not checked before being used to disable a TLB.
In normal case the return value wouldn't be -1. In case of a mis-
configuration during porting to a new board, checking the return value
may be helpful to reveal some user errors.

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.

935b402eae fsl/mpc85xx: define common serdes_clock_to_string function
This allows to share some common code for the boards that use a corenet
base SoC.

Two different versions of the function are available in
fsl_corenet_serdes.c and fsl_corenet2_serdes.c files.

When using QSGMII protocols, the first lane and third lane on each slot
need to be swapped.

7d0d355fee powerpc/common/vsc3316: remove const from vsc3316_config parameter define
Since the parameters need to be modified according to different Serdes
protocols at runtime, the const will block this. Also remove const from
arrays define used by vsc3316_config.

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
