doc: net: Rewrite network driver documentation
doc/README.drivers.eth seems like a good source for understanding
U-Boot's network subsystem, but is only talking about legacy network
drivers. This is particularly sad as proper documentation would help in
porting drivers over to the driver model.
Rewrite the document to describe network drivers in the new driver model
world. Most driver callbacks/methods are almost identical in their
semantic, but recv() differs in some important details.
Also keep some parts of the original text at the end, to help
understanding old drivers. Add some hints on how to port drivers over.
This also uses the opportunity to reformat the document in reST, on the
way moving it into doc/driver-model and adding it into the structure
there.

phy: Add support for the NC-SI protocol
This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.
NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).
This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).
The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

efi_loader: Implement FileLoad2 for initramfs loading
Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.
The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

mmc: sdhci: fix missing cache invalidation after reading by DMA
This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.
When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.
Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.

The reference manuals for MPC8308 and MPC8309 both say that the
esdhcctl aka DMA Control Register "is implemented as SDHCCR" in the
System configuration registers. Unfortunately, that doesn't mean that
the registers are just mirrors of each other - any write to esdhcctl
is simply ignored. So to actually enable cache snooping, we
unfortunately have to add a little ifdeffery.
There is, naturally, no description of the bit fields of esdhcctl in
the MPC8309 manual, but comparing the description of esdhcctl from the
LS1021A reference manual to the description of the sdhccr in MPC8309,
one also finds that the fields are bit-reversed, so the bit to set is

rockchip: rk3399: split roc-pc-rk3399 out of evb_rk3399
roc-pc-rk3399 board has one user button & three user LED's. Currently
we don't have any code support for these devices. Since button and LED's are
specific to roc-pc-rk3399 board, split it into its own board file and add code
support here.
