2009-04-05mpc5200: reduce delays in i2cJon Smirl
The previous code waited 1000us before checking i2c status. Measurement shows i2c is usually ready in under 50us. Change the polling interval to 15us, loop 6,667 times to keep the polling timeout constant at 100ms.
2009-03-25mpc5200: suppress printf until console initializedJon Smirl
On boards which have the environment in eeprom, i2c_init() is called before the console and RAM are initialized. Suppress printfs until the console is initialized. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Acked-by: Heiko Schocher <hs@denx.de>
2008-12-15i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi
All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h.
