[U-Boot] [PATCH v3 0/3] reduce warnings with W=1

[Jeroen Hofstee]

When compiling u-boot with W=1 there are numerous of warnings.
This patchset attempts to reduce it a bit. One source of false
warnings are the aliases missing a prototype, most of them are
replaced with __weak functions. Others are cause by missing
includes / local functions not be marked as such. At last some
actual missing prototypes are added. These are (hopefully) just
trivial patches, some less than trial is ahead of us.

v3:
  - i2c did contain another alias function, i2c_init_board. This
    time the correct patch is squashed with it. Only this patch
    resend (1/3).

v2:
  - rebase on master (most of this serie is applied, so remaining
    patches are numbered differently.
  - drop "PATCH 25/49 spi: make local functions static". Tom posted
    a more complete cleanup.
  - Drop common/cmd_elf.c: add missing include (a slightly adjusted
    version was applied).
  - split i2c: use __weak (included i2c and l2_cache)
  - redo serial: add prototypes for init functions

Jeroen Hofstee (3):
  i2c: use __weak
  arm926ejs: cache: use __weak
  serial: add prototypes for init functions
