Using (dm_)pci_virt_to_mem() is incorrect to translate the virtual
address in local DRAM to a physical address. The correct macro here
is virt_to_phys() so switch to using this macro.

As virt_to_bus() is now not used any more, this patch also removes
both definitions (DM and non-DM).

This issue was detected while testing the e1000 driver on the MIPS
Octeon III platform, which needs address translation.

- New Allwinner H616 SoC support (sans Ethernet & USB)
- H6 DT update
- Tanix TX6 TV box support
- OrangePi 3 support
- OrangePi Zero2 (H616) support

OrangePi Zero2 is SBC based on Allwinner H616 with 1 GiB of RAM, SD card
support, gigabit ethernet, micro HDMI, WIFI, Bluetooth and 1 USB 2.0
port. It also has two GPIO headers which allows further peripherals to
be used.

The devicetree file is taken from v3 of the OrangePi Zero2 Linux
submission [1], which it's not yet merged.

H616 is very similar to H6 so most of the infrastructure can be reused.
However, two big differences are that it doesn't have functional SRAM A2
which is usually used for TF-A and it doesn't have ARISC co-processor.
It also needs bigger SPL size - 48 KiB.

So far the only difference between the various Allwinner MMC controller
we are concerned about is the mod clock register offset.
This is actually not directly related to the MMC controller IP, but an
integration choice, dependent on the SoC this appears in.

To avoid becoming trapped with some compatible fallback strings, let's
remove the whole struct sunxi_mmc_variant, and replace this with a SoC
based choice, which we can derive from the CONFIG_MACH_SUNx_y symbols.

This will later simplify H616 support.

are not needed otherwise.

The #ifdef CONFIG_xxxPWR conditionals were not working as expected, as
string Kconfig symbols are always "defined" from the preprocessor's
perspective. This lead to unnecessary calls to the GPIO routines, but
also always added a half a second delay to wait for a SATA disk to power
up. Many thanks to Peter for pointing this out!

Fix this by properly comparing the Kconfig symbols against the empty
string. strcmp() would be nicer for this, but GCC does not optimise this
away, probably due to our standalone compiler switches.

So far all GBit users of the sun8i-emac driver were using the "rgmii"
PHY mode, even though this turns out to be wrong. It just worked because
the PHY driver doesn't do the proper setup (yet).
In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the
correct ones.

To allow the DTs to describe the phy-mode correctly, and to stay
compatible with Linux, at least allow those other RGMII modes in the
driver.

This avoids breakage if mainline DTs will be synced with U-Boot.

By default the echo command emits its arguments followed by a line feed.

If any of the arguments contains the sub-string "\c", the line feed is
suppressed.

This does not match shells used in Linux and BSD where the first argument
has to be -n to suppress the line feed.

The hush shell interferes with the parsing of backslashes. E.g. in the
following command line quadruple backslashes are required for suppressing
the line feed:

for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done;

To avoid unexpected behavior the patch changes echo to use -n as first
argument to suppress the line feed.
