753812cb2e dm: serial: Correct logic in serial_find_console_or_panic()
In a final attempt to find a console UART this function uses the first
first available serial device. However the check for a valid device is
inverted.

This code is only executed when there is in fact no serial UART, but at
present it can fail to reach the panic_str() call in this case, and start
trying to use a non-existent UART.

d77447fdb1 serial: pl01x: fix PL010 regression
commit aed2fbef5e
"dm: serial: Tidy up the pl01x driver"
caused a regression on (real hardware) PL010 by omitting
to update the line control register when switching baudrate.

Fix this by inlining the missing write to the baud control
register.

Also renaming the set_line_control() function to
pl011_set_line_control() since this function is clearly
PL011-specific, and it won't suffice to call that to
set up line control.

Tested on the Integrator/AP hardware.

2f964aa7b1 serial: Support an early UART for debugging
This came up in a discussion on the mailing list here:

https://patchwork.ozlabs.org/patch/384613/

My concerns at the time were:
- it doesn't need to be written in assembler
- it doesn't need to be ARM-specific

This patch provides a possible alternative. It works by allowing any serial
driver to export one init function and provide a putc() function. These
can be used to output debug data before the real serial driver is available.

This implementation does not depend on driver model, and it is possible for
it to operate without a stack on some architectures (e.g. PowerPC, ARM). It
provides the same features as the ARM-specific debug.S but with more UART
and architecture support.

9cc36a2b89 dm: core: Add a flag to control sequence numbering
At present we try to use the 'reg' property and device tree aliases to give
devices a sequence number. The 'reg' property is often actually a memory
address, so the sequence numbers thus-obtained are not useful. It would be
better if the devices were just sequentially numbered in that case. In fact
neither I2C nor SPI use this feature, so drop it.

Some devices need us to look up an alias to number them within the uclass.
Add a flag to control this, so it is not done unless it is needed.

Adjust the tests to test this new behaviour.

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

This commit converts UniPhier on-chip serial driver to driver model.

Since UniPhier SoCs do not have Device Tree support, some board files

(Device Tree support for UniPhier platform is still under way.)

Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.

Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.

This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.

The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.

the data register.

Also, when stressing U-Boot a lot with serial input, an overflow can
occur which asserts the S1_OR flag (while not asserting the S1_RDRF
flag). To clear this flag we again just need to read the data
register, hence add this flag to the abort conditions for the while
loop.

Insert a compiler barrier to make sure reading the data register
gets executed after reading the status register.

The nios2-io.h defines hardware registers and bits of several FPGA
IP cores. It could be divided in to the specific drivers, including
altera timer, altera sysid, altera uart and altera jtag uart. The
altera pio and altera spi drivers use their own hardware definitions.
The removal of nios2-io.h will help modularity and maintenance.

093f79ab88 Add a flag indicating when the serial console is ready
For sandbox we have a fallback console which is used very early in
U-Boot, before serial drivers are available. Rather than try to guess
when to switch to the real console, add a flag so we can be sure. This
makes sure that sandbox can always output a panic() message, for example,
and avoids silent failure (which is very annoying in sandbox).

709ea543b9 stdio: Pass device pointer to stdio methods
At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.

For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.

Instead, add a stdio_dev pointer to each of the stdio member functions.

Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

841977df21 serial: ns16550: drop CONFIG_OMAP1610 from the special case
If CONFIG_OMAP1610 is defined, the code returning the fixed value (26)
is enabled. But this case is covered by the following code.

(CONFIG_SYS_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) /
    (MODE_X_DIV * gd->baudrate)
= (48000000 + (115200 * (16 / 2))) / (16 * 115200)
= 48921600 / 1843200
= 26

The "#ifdef CONFIG_OMAP1610" was added by commit 6f21347d more than
ten years ago. In those days, the divide-and-round was not used.
I guess that is why this weird code was added here.

3a56482590 serial_mxc: disable new features of autobaud detection
Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x
reference manuals as follows:

	Autobaud Detection Not Improved-. Disables new features of
	autobaud detection (See Baud Rate Automatic Detection
        Protocol, for more details).

	0 Autobaud detection new features selected
	1 Keep old autobaud detection mechanism

On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features"
occasionally cause the receiver to get out of sync and
continuously produce received characters of '\xff'.

This patch disables the "new feature" on all boards, since
there's no support for auto-baud in U-Boot on any of them.

More details are available in this post on i.MX Community:

7de0fe1ac3 serial/ns16550: add an option to avoid hanging on broken platforms
Some platforms (e.g. IGEPv2 board) has a broken ns16550 UART that
does not set the TEMT bit when the transmitter is empty in SPL.
This makes U-Boot to hang while waiting for TEMT to be set.

Add a new option to avoid this:

CONFIG_SYS_NS16550_BROKEN_TEMT

16550 UART set the Transmitter Empty (TEMT) Bit when all output
has finished and the transmitter is totally empty. U-Boot waits
for this bit to be set to initialize the serial console. On some
broken platforms this bit is not set in SPL making U-Boot to
hang while waiting for TEMT. Define this option to avoid it.

48cbc3a876 serial/ns16550: don't build serial_ns16550 with MIN_FUNCTIONS
CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic
ns16550 output code without pulling in things not needed by the SPL.

This previously only worked with non-MULTI configs.  Recently MULTI was
made mandatory, and MIN_FUNCTIONS fails like this:

drivers/serial/libserial.o: In function `calc_divisor.clone.0':
serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq'
drivers/serial/libserial.o: In function `_serial_getc':

make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1
make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2

With MIN_FUNCTIONS we don't need anything from this file, so don't build
it.  The conditional needs to be in the file itself rather than the
makefile, because the config symbols are only imported to the makefiles
once, not separately for the SPL phase of the build.

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token

powerpc sparse builds yield:

include/common.h:356:22: error: marked inline, but without a definition

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'

also fixed:
ydirectenv.h:60:0: warning: "inline" redefined [enabled by default]

and:

bfb7d7a3d6 serial: Implement default_serial_puts()
U-Boot contains a lot of duplicit implementations of serial_puts()
call which just pipes single characters into the port in loop. Implement
function that does this behavior into common code, so others can make
easy use of it.

This function is called default_serial_puts() and it's sole purpose
is to call putc() in loop on the whole string passed to it.
