This driver works in "new" Data Mover UART mode, so
will be compatible with modern Qualcomm chips only.

Currently, fdtdec_get_addr_size() does not support the address
translation, so it cannot handle device trees with non-straight
"ranges" properties. (This would be a problem with DTS for UniPhier
ARMv8 SoCs.)

The RPi3 typically uses the regular UART for high-speed communication with
the Bluetooth device, leaving us the mini UART to use for the serial
console. Add support for this UART so we can use it.

For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

For Raspberry Pi, we had the input clock rate to the pl011 fixed in
the rpi.c file, but it may be changed by firmware due to user changes
to config.txt. Since the firmware always sets up the uart (default
115200 output unless the user changes it), we can just skip our own
uart init to simplify the boot process and more reliably get serial
output.

reg-offset is the part of standard 8250 binding in the kernel.
It is shifting start of address space by reg-offset.

At present on x86 machines with use cache-as-RAM, the memory goes away just
before board_init_r() is called. This means that serial drivers are
no-longer unavailable, until initr_dm() it called, etc.
Any attempt to use printf() within this period will cause a hang.
To fix this, mark the serial devices as 'unavailable' when it is no-longer
available. Bring it back when serial_initialize() is called. This means that
the debug UART will be used instead for this period.

As the handling for carriage return and line feed is done in the common

In general, a carriage return needs to execute before a line feed.
The patch is to change some serial drivers based on this rule, such
as serial_mxc.c, serial_pxa.c, serial_s3c24x0.c and usbtty.c.

This reverts commit d9a3bec682f9756621615f4306718a356a3230e3.
While this is a correct change to do long term it unfortunately breaks a
number of platforms that are using pdata and not named struct members so
they are getting all of their data after 'base' incorrect.

Enabling this driver requires some DT changes.
Adding DCC to root or main bus:
dcc: dcc {
compatible = "arm,dcc";
u-boot,dm-pre-reloc;
};
Extend alias list to link DCC:
serial0 = &uart0;
serial1 = &uart1;
serial2 = &dcc;
Change stdout-path to point to dcc port.
stdout-path = "serial2:115200n8";
Also add support for debug uart to help with early debug.

Use the driver model version of the function to find the BAR. This updates
the fdtdec function, of which ns16550 is the only user.
The fdtdec_get_pci_bdf() function is dropped for several reasons:
- with driver model we should use 'struct udevice *' rather than passing the
device tree offset explicitly
- there are no other users in the tree
- the function parses for information which is already available in the PCI
device structure (specifically struct pci_child_platdata which is available
at dev_get_parent_platdata(dev)
