We have finished Generic Board conversion for ARM and PowerPC, i.e.
all the boards have been converted except OpenRISC, SuperH, SPARC,
which have not supported Generic Board framework yet.
Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro
defines in include/configs/*.h.

We should not init the console this early since it precludes using driver
model for the UART, since it is not set up at the start of board_init_f().
See the README for more information. The debug UART does not have this
restriction. If we want to do early init with the console on it can be done
in spl_board_init().
Move the preloader_console_init() call from board_init_f() to board_init_r().

There is quite a bit of assembler code that can be removed if we use the
generic global_data setup. Less arch-specific code makes it easier to add
new features and maintain the start-up code.
Drop the unneeded code and adjust the hooks in board_f.c to cope.

This function will be used by both SPL and U-Boot proper. So move it into
a common place. Also change the #ifdef so that the early malloc() area is
not set up in SPL if CONFIG_SYS_SPL_MALLOC_START is defined. In that case
it would never actually be used, and just chews up stack space.

In the following snippet:
if [ ! -x `which $prereq` ]; then
When $prereq does not exist, `which $prereq` evaluates to the empty string,
which results in *no* argument being passed to the -x operator, which then
evaluates to true, which is the equivalent of the prereq having been found. In
order for this to fail as expected, we must pass an empty argument, which then
causes -x to fail. Do this by wrapping the `` in quotes so there's always an
argument to -x, even if the value of the argument is zero-length.

In my patch series to replace fs/fat with "ff.c", I enhanced ff.c to
optimize file reading, so that reads of contiguous clusters are submitted
to the IO device as a single read. This test attempts to torture-test
edge-cases of that enhancement.
BTW, the only way I found to validate that this script actually does
create non-contiguous files was to manually inspect the FAT bitmap in a
hex dump of the FAT image. hdparm --fibmap doesn't work on loop-mounted
filesystems. filefrag -v -e seems to lie about files being contiguous
when they aren't.

In the "Getting Started with Coccinelle - KVM edition" presentation that
has been held by Julia Lawall at the KVM forum 2015 (see the slides at
http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf),
she pointed out some bad return value checks in U-Boot that can be
detected with Coccinelle by using the following config file:
@@
identifier x,y;
identifier f;
statement S;
@@
x = f(...);
(
if (x < 0) S
|
if (
- y
+ x
< 0) S
)
This patch now fixes these issues.

For current U-Boot to initialize status LEDs via status_led_init(), it
is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined.
This may be a particular concern with GPIO LEDs, where __led_init() is
required to correctly set up the GPIO (gpio_request and
gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't
called, which could leave the user with a non-functional "led" command -
due to the fact that the LED routines in gpio_led.c use gpio_set_value()
just fine, but the GPIO never got set up properly in the first place.
I think having CONFIG_STATUS_LED is sufficient to justify a
corresponding call to status_led_init(), even with no STATUS_LED_BOOT
defined. To do so, common/board_r.c needs call that routine, so it now
is exposed via status_led.h.

For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED),
it may be useful to have some generic stubs (wrapper functions)
for the "colored" LEDs.
This allows defining STATUS_LED_* values directly to GPIO numbers,
e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */
To keep those optional, it's probably best to introduce an additional
configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that.
Placing the code in drivers/misc/gpio_led.c also ensures that it
automatically depends on CONFIG_GPIO_LED too.

Convert cache flush to use dm cpu data.
The original cache flush functions are written in assembly
and use CONFIG_SYS_{I,D}CACHE_SIZE... macros. It is difficult
to convert to use cache configuration in dm cpu data which is
extracted from device tree.
The cacheflush.c of Linux nios2 arch uses cpuinfo structure,
which is very close to our dm cpu data. So we copy and modify
it to arch/nios2/lib/cache.c to replace the old cache.S.

Set default icache and dcache configuration for start.S.
We want to remove the CONFIG_SYS_{I,D}CACHE_SIZE...
configuration macros. As we are just barely starting from
reset, there is no luxury of device tree.
We will set some maximum cache configuration so that it will
work for most configurations. This is used only in this
start.S. The speed penalty is only once here.
After start up, during board initialization, cpu information
will be extracted from device tree. Then cache flush operations
will have correct cache configurations.
