[PATCH v4 00/18] Minor board_f/board_r cleanups

[PATCH v4 00/18] Minor board_f/board_r cleanups

[Ovidiu Panait]

v4:
* Drop trap_init declaration from init.h and make arch-specific
implementations static for mips and m68k (on powerpc trap_init is an
asm routine)

v3:
* Use only "default y" for CONFIG_CONSOLE_RECORD_INIT_F Kconfig option
* Add reviewed-by tags

v2:
* Introduce CONFIG_CONSOLE_RECORD_INIT_F Kconfig to eliminate complex ifdef
  around console_record_init in board_f.c
* Add function comments to all routines that get their signatures changed
* Add reviewed-by tags

v1:
* Use IS_ENABLED() instead of #ifdef where possible
* Add int return values to various functions so we can drop multiple initr_*
  stub wrappers
* Clean some arch-specific ifdefs
* Minor CONFIG_HANDOFF patches

[PATCH v4 01/18] common: Kconfig: Introduce CONFIG_CONSOLE_RECORD_INIT_F

[Ovidiu Panait]

Currently, the following #ifdef construct is used to check whether to run
console_record_init() during pre-relocation init:
 defined(CONFIG_CONSOLE_RECORD) && CONFIG_VAL(SYS_MALLOC_F_LEN)

Introduce CONFIG_CONSOLE_RECORD_INIT_F Kconfig option to get rid of the
complex ifdef check. Also, use IS_ENABLED() instead of #ifdef.

In order to remove the arch-specific ifdefs around initr_trap, introduce
arch_initr_trap weak initcall. Implementations for ppc/m68k/mips have
been moved to arch/<arch>/lib/traps.c

Default implementation is a nop stub.

[PATCH v4 17/18] spl: Kconfig: Add SPL dependency to CONFIG_HANDOFF

[Ovidiu Panait]

CONFIG_HANDOFF is used in u-boot proper to locate handoff info from SPL
during pre-relocation init (in setup_spl_handoff). Add explicit dependency
on CONFIG_SPL, to fix the following build error when CONFIG_HANDOFF &&
!CONFIG_SPL:

common/board_f.c: In function ?setup_spl_handoff?:
common/board_f.c:283:4: error: ?gd_t {aka struct global_data}?
has no member named ?spl_handoff?
  gd->spl_handoff = bloblist_find(BLOBLISTT_SPL_HANDOFF,
