When changing from one data interface setting to another, one has to
ensure a specific sequence which is described in the ONFI spec.
One of these constraints is that the CE line has go high after a reset
before a command can be sent with the new data interface setting, which
is not guaranteed by the current implementation.
Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.
Also make sure to actually apply the new data interface setting on the
first die.

The NAND framework provides several helpers to query timing modes supported
by a NAND chip, but this implies that all NAND controller drivers have
to implement the same timings selection dance. Also currently NAND
devices can be resetted at arbitrary places which also resets the timing
for ONFI chips to timing mode 0.
Provide a common logic to select the best timings based on ONFI or
->onfi_timing_mode_default information. Hook this into nand_reset()
to make sure the new timing is applied each time during a reset.
NAND controller willing to support timings adjustment should just
implement the ->setup_data_interface() method.

The generic NAND DT bindings allows one to tweak the ECC strength and
step size to their need. It can be used to lower the ECC strength to
match a bootloader/firmware config, but might also be used to get a better
reliability.
In the latter case, the user might want to use the maximum ECC strength
without having to explicitly calculate the exact value (this value not
only depends on the OOB size, but also on the NAND controller, and can
be tricky to extract).
Add a generic 'nand-ecc-maximize' DT property and the associated
NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best
ECC strength and step-size on their own.

When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*(). U-Boot does not support them in a clean
way. So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.
We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround. Hence this
patch, to find the best home for all printk variants. If you want to
use printk() and friends, please include <linux/printk.h>. This header
is self-contained, and pulls in only a few headers.
When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards. This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.
To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel". (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.
The difference is the loglevel is build-time determined. To save the
image size, lower priority pr_*() are compiled out. I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.
I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent")
extensively used the ndelay function with a calculated parameter
which is dependant on the configured frequency of the I2C bus. If
standard speed is employed, the parameter is usually 10000 (10000ns
period length for 100kHz frequency).
But, since the arm architecture does not implement a proper version of
ndelay, the fallback default from include/linux/compat.h is used,
which defines every ndelay as udelay(1). This causes problems for
slower speeds on arm, since the delay time is now 9us too short for
the desired frequency, which leads to random failures of the I2C
interface.
To remedy this, we implement a proper, parameter-aware ndelay fallback
for architectures that don't implement a real ndelay function.

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.
For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.
I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

The previous commit introduced a useful macro used in makefiles,
in order to reference to different variables (CONFIG_... or
CONFIG_SPL_...) depending on the build context.
Per-image config option control is a PITA in C sources, too.
Here are some macros useful in C/CPP expressions.
CONFIG_IS_ENABLED(FOO) can be used as a shorthand for
(!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
(defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))
For example, it is useful to describe C code as follows,
#if CONFIG_IS_ENABLED(OF_CONTROL)
(device tree code)
#else
(board file code)
#endif
The ifdef conditional above is switched by CONFIG_OF_CONTROL during
the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is
defined).
The macro can be used in C context as well, so you can also write the
equivalent code as follows:
if (CONFIG_IS_ENABLED(OF_CONTROL)) {
(device tree code)
} else {
(board file code)
}
Another useful macro is CONFIG_VALUE().
CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is
undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined.
You can write as follows:
text_base = CONFIG_VALUE(TEXT_BASE);
instead of:
#ifdef CONFIG_SPL_BUILD
text_base = CONFIG_SPL_TEXT_BASE;
#else
text_base = CONFIG_TEXT_BASE;
#endif
This commit also adds slight hacking on fixdep so that it can
output a correct list of fixed dependencies.
If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file,
we want
$(wildcard include/config/foo.h)
in the U-boot proper building context, while we want
$(wildcard include/config/spl/foo.h)
in the SPL build context.

Enable GPMC's prefetch feature for NAND access. This speeds up NAND read
access a lot by pre-fetching contents in the background and reading them
through the FIFO address.
The current implementation has two limitations:
a) it only works in 8-bit mode
b) it only supports read access
Both is easily fixable by someone who has hardware to implement it.
Note that U-Boot code uses non word-aligned buffers to read data into, and
request read lengths that are not multiples of 4, so both partial buffers
(head and tail) have to be addressed.
