2009-02-14i.MX31: Start the I2C clock on driver initialisationGuennadi Liakhovetski
i.MX31 powers on with most clocks running, so, after a power on this explicit clock start up is not required. However, as Linux boots it disables most clocks to save power. This includes the I2C clock. If we then soft reboot from Linux the I2C clock stays off. This breaks the phycore, which has its environment in I2C EEPROM. Fix the problem by explicitly starting the clock in I2C driver initialisation routine.

2008-04-11Revert merge of git://www.denx.de/git/u-boot-arm, commit 62479b18:Wolfgang Denk
Reverting became necessary after it turned out that the patches in the u-boot-arm repo were modified, and in some cases corrupted. This reverts the following commits: 066bebd6353e33af3adefc3404560871699e9961 7a837b7310166ae8fc8b8d66d7ef01b60a80f9d6 c88ae20580b2b01487b4cdcc8b2a113f551aee36 a147e56f03871bba4f05058d5e04ce7deb010b04 d6674e0e2a6a1f033945f78838566210d3f28c95 8c8463cce44d849e37744749b32d38e1dfb12e50 c98b47ad24b2d91f41c09a3d62d7f70ad84f4b7d 8bf69d81782619187933a605f1a95ee1d069478d 8c16cb0d3b971f46fbe77c072664c0f2dcd4471d a574a73852a527779234e73e17e7597fd8128882 1377b5583a48021d983e1fd565f7d40c89e84d63 1704dc20917b4f71e373e2c888497ee666d40380 Signed-off-by: Wolfgang Denk <wd@denx.de>
