[PATCH RESEND 01/18] MIPS: Alchemy: remove PB1000 support
Manuel Lauss
manuel.lauss at googlemail.com
Wed Nov 2 07:53:44 EDT 2011
Noone seems to have test hardware or care anymore. Drop PB1000 support
and along with it the old Alchemy PCMCIA socket driver.
Cc: netdev at vger.kernel.org
Cc: linux-pcmcia at lists.infradead.org
Signed-off-by: Manuel Lauss <manuel.lauss at googlemail.com>
---
Resend with CC's added as requested by Ralf.
Cc'ing netdev for IrDA driver parts and pcmcia for the socket driver
removal.
