Hi all,

This series removes almost all the remaining code that is part of the
legacy iSeries platform.

[PATCH 1/5] tty/hvc_vio: FW_FEATURE_ISERIES is no longer selectable

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1032 bytes --]

so remove the code that tests for it.

Greg, it is probably easiest for this to go through the powerpc tree.

[PATCH 2/5] powerpc: remove FW_FEATURE ISERIES from arch code

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 28527 bytes --]

This is no longer selectable, so just remove all the dependent code.
