Christopher Price posted availability of a patchset to restore EFI Mixed Mode to the latest Android-IA release. Excerpt of announcement:
Enclosed you will find 19 patches that restore EFI Mixed Mode to the latest Android-IA release. We are still running through a BFD linker bug in KernelFlinger that is preventing activation – but it has tested well with GMIN64 and does not appear to block the kernel. Testing and review appreciated. We’d like it committed upstream because it would be very difficult without trunk access to maintain these patches going forward. While we’d like to take credit, Mark Gross and Intel UK really did an excellent job reviving this work – we’ve been incubating and testing for the past few months. This will allow Android-IA to run on the millions of BayTrail-T production tablets that depend on EFI Mixed Mode. Without these patches, Android-IA cannot run on virtually any Bay Trail tablet today, except for maybe IRDA, which isn’t available in many countries currently. These patches should no longer be necessary once Kernel 3.15 is integrated, at which point Mixed Mode will hit mainline… or at least, should hit mainline.
