From: Jonathan Cameron Date: Sun, 27 Feb 2022 13:44:31 +0000 (+0000) Subject: ARM: pxa: remove Intel Imote2 and Stargate 2 boards X-Git-Tag: v6.1-rc5~1757^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=28f74201e37ccf3063e359bfe346b09400af9bab;p=platform%2Fkernel%2Flinux-starfive.git ARM: pxa: remove Intel Imote2 and Stargate 2 boards I have no reason to believe these boards have any more users and I haven't tested them for several years. Removing them may simplify other changes to the various PXA boards people still care about. The recent conversion of pxa2xx_spi to GPIO descriptors for example had to update this board despite no one caring or testing. Great boards that got me started in kernel development, RIP!
