The below patch added eSDHC periperhal clock code initially.
2d9ca2c mmc: fsl_esdhc: Add peripheral clock support
The purpose was to fix up device tree properties "peripheral-frequency"
so that linux could get the periperhal clock by it.
However the implementation on both u-boot and linux was only
for a Freescale SDK release. The linux part implementation had never
been upstreamed. These code should not have been exist on u-boot
mainline.
Let's remove the powerpc part changes but keep the changes in
fsl_esdhc driver. The changes in fsl_esdhc driver could be utilized
to support SD UHS and eMMC HS200/HS400 speed modes for current
Layerscape ARM platforms.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

T1040 and it's variants provide "Single Oscillator Source" Reference Clock Mode.
In this mode, single onboard oscillator(DIFF_SYSCLK) can provide the reference clock
(100MHz) to the following PLLs:
• Platform PLL
• Core PLLs
• USB PLL
• DDR PLL, etc
The cfg_eng_use0 of porsr1 register identifies whether the SYSCLK (single-ended) or
DIFF_SYSCLK (differential) is selected as the clock input to the chip.
get_sys_info has been enhanced to add the diff_sysclk so that the
various drivers can be made aware of ths diff sysclk configuration and
act accordingly.
Other changes:
-single_src to ddr_refclk_sel, as it is use for checking ddr reference clock
-Removed the print of single_src from get_sys_info as this will be
-printed whenever somebody calls get_sys_info which is not appropriate.
-Add print of single_src in checkcpu as it is called only once during initialization

Erratum A007212 for DDR is about a runaway condition for DDR PLL
oscilliator. Please refer to erratum document for detail.
For this workaround to work, DDR PLL needs to be disabled in RCW.
However, u-boot needs to know the expected PLL ratio. We put the
ratio in a reserved field RCW[18:23]. U-boot will skip this workaround
if DDR PLL ratio is set, or the reserved field is not set.
Workaround for erratum A007212 applies to selected versions of
B4/T4 SoCs. It is safe to apply the workaround to all versions. It
is helpful for upgrading SoC without changing u-boot. In case DDR
PLL is disabled by RCW (part of the erratum workaround), we need this
u-boot workround to bring up DDR clock.

Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.
So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclock
DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
normal clocking mode by DDR_Reference clock
-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
single source clocking mode by DIFF_SYSCLK
Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.
