Tang Yuantian aade20046b mpc85xx/t104x: Add deep sleep framework support
When T104x soc wakes up from deep sleep, control is passed to the
primary core that starts executing uboot. After re-initialized some
IP blocks, like DDRC, kernel will take responsibility to continue
to restore environment it leaves before.

Tang Yuantian 5aef4c86f3 mpc85xx: Add support for the supplement configuration unit register
The supplement configuration unit (SCFG) provides chip-specific
configuration and status registers for the device. It is the chip
defined module for extending the device configuration unit (DCFG)
module. It provides a set of CCSR registers in addition to those
available in the device configuration unit.
The base address for this unit is 0x0F_C000.

Priyanka Jain 2ee6c52e22 driver/net/fm/memac_phy: Initialize mdio_clock for SoCs wih FMANv3
MDIO clock needs to be initialized in u-boot code for SoCs
having FMAN-v3(v3H or v3L) controller due to below reasons

-On SoCs that have FMAN-v3H  like B4860, default value of
MDIO_CLK_DIV bits in mdio_stat(mdio_cfg) register generates
mdio clock too high (much higher than 2.5MHz), violating the
IEEE specs.
-On SOCs that have FMAN-v3L like T1040, default value of
MDIO_CLK_DIV bits is zero, so MDIO clock is disabled.

So, for proper functioninig of MDIO, MDIO_CLK_DIV bits needs to
be properly initialized.
Also this type of initialization is generally done in
PBI(pre-bootloader) phase using rcw.But for chips like T1040
which support deep-sleep, such type of initialization cannot be
done in PBI phase due to the limitation that during deep-sleep
resume, FMAN (MDIO) registers are not accessible in PBI phase.
So, mdio clock initailization must be done as part of u-boot.

This initialization code is implemented in memac_phy.c which
gets compiled only for SoCs having FMANv3, so no extra compilation
flag is required.

York Sun c3678b0937 powerpc/mpc85xx: Add workaround for erratum A007212
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.

Paul Burton 6fb49e4aa0 pcnet: force ordering of descriptor accesses
The ordering of accesses to the rx & tx descriptors is important, yet
the send & recv functions accessed them via regular structure accesses.
This leaves the compiler with the opportunity to reorder those accesses
or to hoist them outside of loops. Prevent that from happening by using
readl & writel to access the descriptors. As a nice bonus, this removes
the need for the driver to care about endianness.
