Re: [PATCH v3 0/4] support smc91x on mainstone and devicetree

This serie aims at bringing support to mainstone board on a device-tree based
build, as what is already in place for legacy mainstone.

The bulk of the mainstone "specific" behavior is that a u16 write doesn't work
on a address of the form 4*n + 2, while it works on 4*n.

The legacy workaround was in SMC_outw(), with calls to
machine_is_mainstone(). These calls don't work with a pxa27x-dt machine type,
which is used when a generic device-tree pxa27x machine is used to boot the
mainstone board.

Therefore, this serie enables the smc91c111 adapter of the mainstone board to
work on a device-tree build, exaclty as it's been working for years with the
legacy arch/arm/mach-pxa/mainstone.c definition.

As a sum up, this extends an existing mechanism to device-tree based pxa platforms.

Series applied, thanks.
