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.
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
