12a3e1ada0 arm: init: save previous bootloader data
When u-boot is used as a chain-loaded bootloader (replacing OS kernel),
previous bootloader leaves data in RAM, that can be reused.

For example, on recent arm linux system, when chainloading u-boot,
there are initramfs and fdt in RAM prepared for OS booting. Initramfs
may be modified to store u-boot's payload, thus providing the ability to
use chainloaded u-boot to boot OS without any storage support.

Two config options added:
- SAVE_PREV_BL_INITRAMFS_START_ADDR
  saves initramfs start address to 'prevbl_initrd_start_addr' environment
  variable
- SAVE_PREV_BL_FDT_ADDR
  saves fdt address to 'prevbl_fdt_addr' environment variable

42fdcebf85 event: Convert misc_init_f() to use events
This hook can be implmented using events, for the three boards that
actually use it.

Add the event type and event handlers. Drop CONFIG_MISC_INIT_F since we
can just use CONFIG_EVENT to control this. Since sandbox always enables
CONFIG_EVENT, we can drop the defconfig lines there too.

2fd81be11c common: board_r: move init_addr_map() to init.h
asm/mmu.h include is currently guarded by CONFIG_ADDR_MAP ifdef because
the header is only present on arm and powerpc. In order to remove the
dependency on this header and the associated ifdef, move init_addr_map()
declaration to init.h, since it is only called during the common init
sequence.

98592c7509 bdinfo: Rename function names to be clearer
At present we have bdinfo_print_num() to print unsigned long numbers.
We also have print_phys_addr() which accept numbers that might be
64-bit on a 32-bit platform.

Rename these 2 functions to be clearer:

bdinfo_print_num() => bdinfo_print_num_l()
print_phys_addr()  => bdinfo_print_num_ll()

While we are here, make bdinfo_print_num_ll() public so that it can
be used outside cmd/bdinfo.c in the future.

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.

81e7cb1e71 board_f: Introduce arch_setup_bdinfo initcall
Certain architectures (ppc, mips, sh, m68k) use setup board_part1 and
setup_board_part2 calls during pre-relocation init to populate gd->bd
boardinfo fields. This makes the generic init sequence cluttered with
arch-specific ifdefs.

In order to clean these arch-specific sequences from generic init,
introduce arch_setup_bdinfo weak initcall so that everyone can define their
own bdinfo setup routines.

5764ea2df4 Revert "board_f: Use static print_cpuinfo if CONFIG_CPU is active"
This reverts commit c0434407b5.

It turns out commit c0434407b5 broke some boards which have DM CPU
driver with CONFIG_DISPLAY_CPUINFO option on. These boards just fail
to boot when print_cpuinfo() is called during boot.

Fixes are already sent to ML and in u-boot-dm/next, however since
we are getting close to the v2018.11 release, it's safer we revert
the original commit.

This commit should be reverted after v2018.11 release.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
