28663622cf arm: s5p4418: dm_serial: remove old code / add DEBUG_UART
Remove init of UART-clock and UART-reset in arch_cpu_init(). Add DEBUG_UART
to s5p4418_nanopi2_defconfig.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@

    + reset_cpu(void)
    { ... }

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

d1611086e0 arm: add support for SoC s5p4418 (cpu) / nanopi2 board
Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01:
- SPL not supported yet --> no spl-dir in arch/arm/cpu/armv7/s5p4418/.
  Appropriate line in Makefile removed.
- cpu.c: '#include <cpu_func.h>' added.
- arch/arm/cpu/armv7/s5p4418/u-boot.lds removed, is not required
  anylonger.
- "obj-$(CONFIG_ARCH_NEXELL) += s5p-common/" added to
  arch/arm/cpu/armv7/Makefile since s5p-common/pwm.c is used instead
  of drivers/pwm/pwm-nexell.c.
- s5p4418.dtsi: '#include "../../../include/generated/autoconf.h"'
  removed, is not necessary, error at out-of-tree building.
  '#ifdef CONFIG_CPU_NXP4330'-blocks (2x) removed. Some minor changes
  regarding mmc. 'u-boot,dm-pre-reloc' added to dp0 because of added
  DM_VIDEO support.
- board/s5p4418/ renamed to board/friendlyarm/
- All s5p4418-boards except nanopi2 removed because there is no
  possibility to test the other boards.
- Kconfig: Changes to have a structure like mach-bcm283x (RaspberryPi),
  e.g. "config ..." entries moved from/to other Kconfig.
- "CONFIG_" removed from several s5p4418/nanopi2 specific defines
  because the appropriate values do not need to be configurable.
- nanopi2/board.c: All getenv(), getenv_ulong(), setenv() and saveenv()
  renamed to env_get(), env_get_ulong(), env_set() and env_save(),
  respectively. MACH_TYPE_S5P4418 is not defined anymore, therefore
  appropriate code removed (not necessary for DT-kernels).
- nanopi2/onewire.c: All crc8() renamed to crc8_ow() because crc8() is
  already defined in lib/crc8.c (with different parameters).
- dts: "nexell,s5pxx18-i2c" used instead of "i2c-gpio", i2c0 and
  i2c1 added. gmac-, ehci- and dwc2otg-entries removed because the
  appropriate functionality is not supported yet. New mmc-property
  "mmcboost" added.
  s5p4418-pinctrl.dtsi: gmac-entries removed, mmc- and i2c-entries
  added.
- '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where
  possible (and similar).
