The pfuze100 is the PMIC connected to the I2C bus. Currently, the I2C driver is disabled which prevents the PMIC from operating.
This patch enables the I2C which also enables the PMIC in U-Boot. This also keeps the PMIC and I2C disabled in SPL due to size constraints of SPL.
I understand the constrain issue, but instead of disabling I2C support on SPL is it possible to enable SPL_OF_PLATDATA and save some space? I haven't test this feature on a real board, but it should reduce SPL size.
