This reverts commit 0c00f65653.
The initial commit was my fault. There are two boards out there:
P2020RDB and P2020RDB-PC. I wasn't aware of that and assumed that I have
a RDB board in front of me while I the RDB-PC. This patch makes it work
for the RDB-PC variant and breaks it for the RDB. Now there is a device
tree file available for the RDB-PC which was not there earlier. So with
this revert, everything gets back to normal :)

This is here most likely since the FSL bsp. Back in the FSL bsp it was
set to 50Mhz and working. However the driver divided the SoC freq. only
by 2. According to the TRM the platform clock (which the manual refers
in its formula) is the system clock divided by two. So in the end it has
to divide by 4 and this is what the fsl-spi driver in tree is doing.
Since then the flash is not wokring I guess. After chaning the freq from
50Mhz to 40Mhz like others do then I can access the flash.

It is not at 0xffa00000. According to current u-boot source the NAND
controller is always at 0xff800000 and it is either at CS0 or CS1
depending on NAND or NAND+NOR mode. In 36bit mode it is shifted to
0xfff800000 but it has always an eight there and never an A.

Systems which use the fsl_pq_mdio driver need to specify an
address for TBI PHY transactions such that the address does
not conflict with any PHYs on the bus (all transactions to
that address are directed to the onboard TBI PHY). The driver
used to scan for a free address if no address was specified,
however this ran into issues when the PHY Lib was fixed so
that all MDIO transactions were protected by a mutex. As it
is, the code was meant to serve as a transitional tool until
the device trees were all updated to specify the TBI address.
The best fix for the mutex issue was to remove the scanning code,
but it turns out some of the newer SoCs have started to omit
the tbi-phy node when SGMII is not being used. As such, these
devices will now fail unless we add a tbi-phy node to the first
mdio controller.

Utilize new split between board & SoC, and new SoC device trees split
into pre & post utilizing 'template' includes for SoC IP blocks.
Other changes include:
* Moved to specifying interrupt-parent for mpic at root
* Moved to 4-cell mpic interrupt cells to support MPIC timers
* Reworked PCIe nodes to allow supportin IRQs for controller (errors) and
moved PCI device IRQs down to virtual bridge level
* Updated spi node to new espi binding specification
* Renamed 'sdhci' node to 'sdhc'
* Changed GPIO compatiable from 'fsl,mpc8572-gpio' to 'fsl,pq3-gpio' as the
'mpc8572' compatiable is to deal with a 'mpc8572' specific to an erratum
* Fixed wrong reg offsets for mdio nodes associated with etsec2 &
* etsec3
* Dropping "fsl,p2020-IP..." from compatibles for standard blocks

The eTSEC includes a PTP clock with quite a few features. This patch adds
support for the basic clock adjustment functions, plus two external time
stamps, one alarm, and the PPS callback.

PCIe device in legacy mode can trigger interrupts using the wires #INTA,
#INTB ,#INTC and #INTD. PCI devices are obligated to use #INTx for
interrupts under legacy mode. Each PCI slot or device is typically wired
to different inputs on the interrupt controller.
So, Define interrupt-map and interrupt-map-mask properties for device tree
to of map each PCI interrupt signal to the inputs of the interrupt
controller.
