[U-Boot] [PATCH 0/7] Switch rockchip firefly to using tiny-printf

[Sjoerd Simons]

The Rockchip rk3288 SPL was always too close to the 32k limit, either
needing gcc 5 or a patched gcc (with some constant string GC fixes) to
actually stay (just) below 32k. With recent changes, it unfortunatly
went over with common gcc versions.

This serie switches the firefly SPL to use tiny-printf instead of the
printf from vsprint, saving around 1800 bytes in the final binary to
bring it under the limit with a bit more margin again.



Sjoerd Simons (7):
  spl: use panic_str instead of panic
  spl: mmc: Explicitly init mmc struct
  lib/tiny-printf.c: Implement vprintf
  lib: Split panic functions out of vsprintf.c
  lib: split out strtoxxxx functions out of vsprintf.c
  mmc: mmc: Don't use sprintf when using tiny-printf
  rockchip: firefly: Use tiny-printf
