DP83822I: RMII in master mode

Hi,

I use AM3352 along with DP83822I on my custom board.
The ETH uses an RMII in master mode.

The ETH is working correctly, but I have to set registers via MDIO during OS boot.
I use the following sequence to configure DP83822I:

// write 0x4300 to 0x462 extended register
mii write 1 0d 1f
mii write 1 0e 462
mii write 1 0d 401f
mii write 1 0e 4300
// write 0x61 to 0x17 register
mii write 1 17 61
// PHY reset
mii write 1 1f 4000

Questions:
1) Do I configure this registers correctly to switch DP83822I into RMII master mode?

2) Can I configure the DP83822I to work in this configuration using bootstrap resistors and not the MDIO interface?

Regards
Adam
