We need inline versions of armlinux_set* exactly when
CONFIG_ARM_LINUX is not set, because this is the symbol

From Linux commit 69349c2dc01c489eccaa4c472542c08e370c6d7e:
Using IS_ENABLED() within C (vs. within CPP #if statements) in its
current form requires us to actually define every possible bool/tristate
Kconfig option twice (__enabled_* and __enabled_*_MODULE variants).
This results in a huge autoconf.h file, on the order of 16k lines for a
x86_64 defconfig.
Fixing IS_ENABLED to be able to work on the smaller subset of just
things that we really have defined is step one to fixing this. Which
means it has to not choke when fed non-enabled options, such as:
include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]
The original prototype of how to implement a C and preprocessor
compatible way of doing this came from the Google+ user "comex ." in
response to Linus' crowdsourcing challenge for a possible improvement on
his earlier C specific solution:
#define config_enabled(x) (__stringify(x)[0] == '1')
In this implementation, I've chosen variable names that hopefully make
how it works more understandable.

This fix a clock inaccuracy in get_time_ns (used by sleep, time, etc).
At i.MX53 power-on GPT clock is typically 55500000 Hz, and it will be used
to calc the clock multiplier. After call imx53_init_lowlevel() GPT clock
will changed (e.g. to 66666666 Hz), but multiplier not. To fix this behavior call
clock_notifier_call_chain() after changing clock in imx53_init_lowlevel().

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

The name "serial_ns16550" is not handy because the devices
will have the names like "serial_ns165500", "serial_ns165501",
"serial_ns165502" etc.
The names like "ns16550_serial0" and "ns16550_serial1" look
much better.
Also it is reasonable to make serial driver's names unification.
E.g. see the names for drivers in drivers/serial directory:
"netx_serial",
"mpc5xxx_serial",
"altera_serial",
"s3c_serial",
"imx_serial",
"pxa_serial",
"blackfin_serial",
"stm_serial",
"pl010_serial",
and even "g_serial" in ./drivers/usb/gadget/serial.c

CRC32 for /dev/mem 0x83fff000 ... 0x83fffffe ==> 0xa080584bbarebox@Very long board name:/
The problem here was that the return value of
lseek(fd, 0x83f00000, SEEK_SET) (which is 0x83f00000) was casted to an
int (which is -2081423360), returned to do_crc and interpreted as
error there without yielding another error message.
This also makes
crc32 -f /dev/mem 0xffffffff+0x1
die on a NULL pointer exception instead of reporting:
