startup: Fix do_autoboot_countdown() running multiple times ...

The comment above do_autoboot_countdown() states: "This function can be
called multiple times, it is executed only the first time.". Since
1973892533 ("startup: don't clobber original autoboot state") This is no
longer the case. Bring back the old and documented behaviour.

startup: register autoboot vars in initcall ...

globalvars should be registered early so that code modifying them also
updates the backing store pointer. Move registering of
global.autoboot_abort_key, global.autoboot_timeout and global.autoboot
to an initcall.

devinfo: print device parent along with device info ...

Especially for "virtual" devices (e.g. wdog0 or mmc2), it is often
useful to know the corresponding hardware device.

Instead of always having to search through plain devinfo, just
include this information in the output when running
`devinfo device`.

kbuild: remove AS variable ...

The assembler files in the barebox are *.S instead of *.s, so they must
be preprocessed. Since 'as' of GNU binutils is not able to preprocess,
we always use $(CC) as an assembler driver.

Remove AS variable.

Linux also removed AS. See Linux commits:

 aa824e0c962b ("kbuild: remove AS variable")
 1ca0c2f61211 ("kbuild: remove unused AS assignment")

watchdog: f71808e: maintain watchdog timeout occurred flag ...

If we experience a watchdog reset, the indicating flag should persist
till the Linux driver had a chance to see it.

The flag bit is special however in that writing 1 clears the bit and
writing 0 keeps it intact, i.e. :

Bit
read written  result
  0     0     = 0
  1     0     = 1
  0     1     = 0
  1     1     = 0

So in the bootloader, we should write a zero always. The OS on the
other hand can either write 1 or the old value after reading to
clear the flag.

MIPS: correctly work with disabled CONFIG_MMU ...

There are some issues with CONFIG_MMU=n in MIPS configuration
(e.g. qemu-malta_defconfig):

  * "Cannot request SDRAM region for stack" error message on start;
  * empty kseg1_ram0 region in the iomem command output.

The patch fixes the problems by forcing KSEG1 memory region usage
for CONFIG_MMU=n MIPS configurations.
