[U-Boot] [PATCH 0/3] arm: vf610: Add QSPI support for VF610

[Alison Wang]

This series contain QSPI support for Freescale Vybrid VF610.

The QSPI(Quad Serial Peripheral Interface) acts as an interface to one single
or two external serial flash devices, each with up to 4 bidirectional data lines.

QSPI has a Look-update-table(LUT) which consists of a number of pre-programmed
sequences. Each sequence is basically a sequence of instruction-operand pairs
which when executed sequentially generates a valid serial flash transaction.

This driver has been tested on VF610TWR.
