After calibrating radio you can find few PHY writes in MMIO dumps:
 phy_read(0x0009) -> 0x0000
phy_write(0x01ce) <- 0x03dd
phy_write(0x01cf) <- 0x03d9
phy_write(0x01d0) <- 0x03d5
phy_write(0x01d1) <- 0x0424
phy_write(0x01d2) <- 0x0429
phy_write(0x01d3) <- 0x042d
By comparing to N-PHY code we found out that they are PHY tables for
channel switching plus band info read at the beginning.

Closed drivers kill radio right after reading radio version and MACCTL,
so it was easy to find related PHY ops:
 phy_read(0x0810) -> 0x0000
phy_write(0x0810) <- 0x0000
