Parent:: 81:7d30d6019079
Child:: 90:cb3d968589d8

Release 85 of the mbed library



Main changes:



- K64F Ethernet fixes

- Updated tests

- Fixes for various mbed targets

- Code cleanup: fixed warnings, more consistent code style

- GCC support for K64F



There is a known issue with the I2C interface on some ST targets. If you

find the I2C interface problematic on your ST board, please log a bug

against this on mbed.org.
