Commit f29f804a93 generalized the TLB
mapping function, but made the DDR mapping leftover size to zero,
causing the message not printed.

8d3eaa9709 powerpc/mpc85xx: use correct dma compatible for several SoCs
Newer qoriq socs have an updated dma ip block with a
different compatible. Let's make sure we use the proper
string so that the dmas get their liodn.
In order to have the means to specify the compatible
string, the liodn setting macros were updated to receive
a new parameter for it.
The following SoCs were changed to use the new compatible:
 T1023/4, T1040, T2080/1, T4240, B4860.

b24f6d401c powerpc/b4860qds: add workaround for XFI
XFI does not work stable on current board, it's due to heat sink issue,
to make it work stable the board needs additional heat sink, enable two
XFI lanes only. Right now we do not have such an erratum for the issue,
so use a define CONFIG_SYS_FSL_B4860QDS_XFI_ERR to identify it.
The workaround will only be used in XFI protocols and only if the
hwconfig indicates that XFI is prefered.

A new VSC3308 config function is used instead of re-use the original
function, to avoid making the function complex and ugly.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

This commit adds:

 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

creats a LAW to enable access of TDM DMA to CCSR by
mapping CCSR to overlap with DDR.
A hole of 16M is created in memory using device tree. This
workaround law is set only if "tdm" is defined in hwconfig.
Also disable POST tests and add LIODN for TDM

b6808cd82d powerpc/serdes: Add the workaround for erratum A-007186
SerDes PLL is calibrated at reset. When the junction temperature
delta from the time the PLL is calibrated exceeds +56C/-66C,
jitter may increase and can cause PLL to unlock.

This workaround overwrite the SerDes registers with new values,
to calibrate SerDes registers.
These values are known to work fine for all temperature ranges.

This workaround is valid for B4, T4 and T2 platforms, so
added in their config.

9855b3beca powerpc/mpc85xx: Add workaround for DDR erratum A004508
When the DDR controller is initialized below a junction temperature of
0°C and then operated above a junction temperature of 65°C, the DDR
controller may cause receive data errors, resulting ECC errors and/or
corrupted data. This erratum applies to the following SoCs and their
variants: MPC8536, MPC8569, MPC8572, P1010, P1020, P1021, P1022, P1023,
P2020.

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.

As errata A-007186, we need to use the alternate serdes
protocol instead of those impacted protocols.

- add support for serdes protocols: 0x1b, 0x50, 0x5e,
  0x64, 0x6a, 0xd2, 0x67, 0x70.
- update t2080_rcw.cfg to adapt to new rcw_66_15 for
