Any restrictions on which pins can be assigned to SPI pins?

[la-ble]

Are there any pins that I can NOT use for SPI on the nRF51822? I'm not seeing any notes in the latest documentation but would like to make extra sure before I spin a board. Thank you.

@labs-stellios: No, there is no restriction. You can use any pins for SPI, except for pin P0.31 on QFN package, which is not wired out physically.
