x86: Support saving MRC data from SPL
When SPL is used to set up the memory controller we want to save the MRC
data in SPL to avoid needing to pass it up to U-Boot proper to save. Add a

x86: broadwell: Allow SDRAM init from SPL
At present, for broadwell, SDRAM is always set up in U-Boot proper since
the 64-bit mode (which uses SDRAM init in SPL) is not supported.
Update the code to allow SDRAM init in SPL instead so that U-Boot proper
can be loaded into SDRAM and run from there. This allows U-Boot to be
compressed to reduce space, since it is not necessary to run it directly
from flash. It could later allow us to support 64-bit U-Boot on broadwell.

x86: Add a way to reinit the cpu
We cannot init the CPU fully both than once during a boot. Add a new
function which can be called to figure out the CPU identity, but which
does not change anything. For x86_64, this is empty for now.
Unfortunately this has a dramatic impact on the pre-relocation memory
used on x86 platforms (increasing it by 2KB) since it increases the
overhead for each PCI device from 220 bytes to 412 bytes.
This means that all PCI devices have the controller struct associated
with them. The solution is to move the regions[] member out of the array,
makes its size dynamic, or split UCLASS_PCI into controllers and
non-controllers, as the comment suggests.
For now, revert the commit to get things running again.

spl: Allow sandbox to build a device-tree file
At present only OF_SEPARATE is considered valid for building a device-tree
file in SPL. However sandbox uses OF_HOSTFILE instead. Update the logic to
handle this and make it easier to understand.
Note that the new logic is not quite the same as the old logic. It was
previously assumed that checking for:
producing 'yy' meant that the first two were 'y' and the last was empty.
Strictly speaking it would be possible for any two of the three to be 'y'
and still yield the same result. However, that was not the intention of
the new logic, since OF_PLATDATA always ensures that no device-tree file
is included. So in effect the new logic is the same, with the addition of
OF_HOSTFILE as an option for OP_SEPARATE.

net: phy: realtek: Introduce quirk to mark RXC not stoppable
When EEE is supported by the PHY and the driver allows it, libphy in the
kernel is configuring the PHY to stop receiving the xMII clock while it
is signaling LPI. While this (usually) works fine in the kernel this is
causing issues in U-Boot when rebooting from the linux kernel with this
bit set (without having the possibility to reset the PHY) where the PHY
suddenly stops working.
A new quirk is introduced to unconditionally reset this bit. If the
quirk is not enabled using the proper configuration symbol, the PHY state

1. Using two new MMD access function hooks in the PHY driver. These
functions can be implemented when the PHY driver does not support the
standard IEEE Compatible clause 45 access mechanism described in clause
22 or if the PHY uses its own non-standard access mechanism.
2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable
DEVADs.
