riscv: Introduce CONFIG_XIP to support booting from flash
When U-Boot boots from flash, during the boot process,
hart_lottery and available_harts_lock variable addresses
point to flash which is not writable. This causes boot
failures on AE350. Introduce a config option CONFIG_XIP
to support such configuration.

riscv: qemu: Use correct SYS_TEXT_BASE for S-mode on 32bit system
For 32bit system, the OpenSBI (or BBL) will jump to 0x80400000 address
in S-mode whereas for 64bit system it will jump to 0x80200000 address
in S-mode.
Currently, the S-mode U-Boot sets SYS_TEXT_BASE to 0x80200000 for both
32bit and 64bit system. This breaks S-mode U-Boot for 32bit system.
This patch sets different SYS_TEXT_BASE for 32bit and 64bit system so
that S-mode U-Boot works fine for both.
After updating Fedora/RISCV kernel to 5.1-rc3+ the size increased above
the current threshold. Looking into HiKey, Dragonboards, etc. seems that
SZ_64M is a popular option.
This sucessfully boots Fedora/RISCV with 5.1-rc3+ kernel on QEMU 4.0 (master)

net: phy: micrel: Find Micrel PHY node correctly
In some of the device trees that specify skew values for KSZ90x1 PHYs
the values are stored (incorrectly) in the MAC node, whereas in others
it is in an 'ethernet-phy' subnode. Previously the code would fail to
find and program these skew values, so this commit changes it to look
for an "ethernet-phy" subnode first, and revert to looking in the MAC
node if there isn't one.
The device trees affected (where the skew values are in a subnode) are
imx6qdl-icore-rqs.dtsi, r8a77970-eagle.dts, r8a77990-ebisu.dts,
r8a77995-draak.dts, salvator-common.dtsi, sama5d3xcm.dtsi,

socfpga_stratix10_socdk.dts and ulcb.dtsi. Before this change the skew
values in these device trees would be ignored.
The device trees where the skew values are in the MAC node are
socfpga_arria10_socdk.dtsi, socfpga_arria5_socdk.dts,

net: phy: micrel: Use correct skew values on KSZ9021
Commit ff7bd212cb8a ("net: phy: micrel: fix divisor value for KSZ9031
phy skew") fixed the skew value divisor for the KSZ9031, but left the
code using the same divisor for the KSZ9021, which is incorrect.
The preceding commit c16e69f702b1 ("net: phy: micrel: add documentation
for Micrel KSZ90x1 binding") added the DTS documentation for the
KSZ90x1, changing it from the equivalent file in the Linux kernel to
correctly state that for this part the skew value is set in 120ps steps,
whereas the Linux documentation and driver continue to this day to use
the incorrect value of 200 that came from the original KSZ9021 datasheet
before it was corrected in revision 1.2 (Feb 2014).
This commit sorts out the resulting confusion in a consistent way by
making the following changes:
- Update the documentation to be clear about what the skew values mean,
in the same was as for the KSZ9031.
- Update the Micrel PHY driver to select the appropriate divisor for
both parts.
- Adjust all the device trees that state skew values for KSZ9021 PHYs to
use values based on 120ps steps instead of 200ps steps. This will result
in the same values being programmed into the skew registers as the
equivalent device trees in the Linux kernel do, where it incorrectly
uses 200ps steps (since that's where all these device trees were copied
from).

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: Support booting with TPL
Some boards want to use TPL as the first phase of U-Boot. This allows
selection of A or B SPL phases, thus allowing the memory init to be
upgraded in the field.
Add a new Kconfig option for this.

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.

binman: Don't show image-skip message by default
This message is not very important since it is simply indicating that the

level is above the default.
Also drop the unnecessary extra newline on this message, which causes two

binman: Don't generate an error in 'text' entry constructor
It is not good practice to raise an exception in a constructor. In this

out the images that get built.
Move the exception to where the data is actually used.

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
is not changed.

net: phy: Add generic helpers to access MMD PHY registers
Two new helper functions (phy_read_mmd() and phy_write_mmd()) are added
to allow access to the MMD PHY registers.
The MMD PHY registers can be accessed by several means:
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.
3. The standard clause 45 access extensions to the MMD registers through
the indirection registers (clause 22) in all the other cases.
