This change should be a no-op in terms of behavior, but it makes code
less confusing when PARAM_TYPE_* matches the type used in the type
cast.

A simpler way to make pattern to trigger immediately is to initialize
blink_next_event to 0 instead of current time value. Save a function

Previous implementation used to add a number to the device names
for devices registered from the device tree which did not have a 'reg'
property, thus a device node named "state" resulted in a device name
"state.<x>". Current implementation skips that number and we get a
device named "state". This conflicts with our barebox state
implementation which tries to register a device named "state" itself.
We could rename the state device nodes of all our device trees, but it
causes less trouble to rename the devices.
This adds a ".of" suffix to the device names for devices registered from
the device tree which also has the nice effect that they now can easily
be recognized.

The socfpga xload images are limited to 64KiB. This doesn't fit if
multiple boards are selected. The reason is that we include huge
C files and arrays in the early init code which get compiled once
for each board. -ffunction-sections is without effect here since all
functions have the same name and hence we get the same function
multiple times in the same section.
To overcome this we surround all function names with a SECT() macro which
is used to add a board specific prefix to the section names. This way
-ffunction-sections can now do its work and discard unused functions.

The resolv() function used to return the IP address. When net_udp_new()
fails we return an error code though which the callers of resolv() take
as an IP address. This is wrong of course and we could return 0 in this
case. Instead we return an error code and pass the resolved IP as a
pointer which allows us to return proper error codes.
This patch also adds error messages and error returns to the various
callers of resolv() which used to just continue with a zero IP and
let the user figure out what went wrong.

At least some MTD_NO_ERASE devices like MRAM do not specify a sensible
erase block size; instead, erasesize is equal to the whole flash size. This
leads to an EINVAL return from mtd_erase_align() whenever a partial erase
is attempted.
At least on the MRAM I tested, a full flash erase did not return an error,
but it did not have any effect on the flash either. As erase seems to be
entirely unsupported on this class of devices, and it is not necessary
anyways, it's better to return early with EOPNOTSUPP.
This fixes envfs_save() on a partitioned MRAM.

Do nand reset before write protect check.
If we want to check the WP# low or high through STATUS READ and check bit 7,
we must reset the device, other operation (eg.erase/program a locked block) can
also clear the bit 7 of status register.
As we know the status register can be refreshed, if we do some operation to trigger it,
for example if we do erase/program operation to one block that is locked, then READ STATUS,
the bit 7 of READ STATUS will be 0 indicate the device in write protect, then if we do
erase/program operation to another block that is unlocked, the bit 7 of READ STATUS will
be 1 indicate the device is not write protect.
Suppose we checked the bit 7 of READ STATUS is 0 then judge the WP# is low (write protect),
but in this case the WP# maybe high if we do erase/program operation to a locked block,
so we must reset the device if we want to check the WP# low or high through STATUS READ and
check bit 7.

-Wmissing-prototypes is a useful warning, so add it to the build.
With this we can detect conflicting function prototypes. When a file
implements a function but doesn't include the header file which
provides the prototype for it then conflicting prototypes would go
unnoticed without this warning.
MIPS already had that warning, so we can remove it from the MIPS
Makefile.
