Hey,
this is a patch series updating the driver interface of the two i2c
chips (mc13892 and mc9sdz60) needed to boot the i.MX35 3stack board.
They no longer export their i2c interface but export now much cleaner
_reg_read, _reg_write and _set_bits functions.
The next pach adopts the i.MX35 to the new driver interface.
Two cleanup patches follow. Then the environment partition is increased
to hold a splash image. The environemnt itself is updated to support
jffs2 and ubi/ubifs. The last patch updates the defconfig.
Please review and consider to apply.
This patch series (based on v2009.12.0) can be pulled, too.
Cheers, Marc
