Some Older ARM Platforms Will Be Saved While Others On The Chopping Block For Linux
Several platforms like Axxia, Broadcom Kona, Digicolor, Dove, Nspire, and Spear are no longer expected for removal at this time. Work on them will supposedly resume otherwise they might be dropped in the future.
Meanwhile ARM platforms still looking to be dead upstream and thus pushing for removal are EFM32, PicoXcell, PRIMA2, Tango, U300, and ZX. ASM9260 and VT8500 are also expected for removal.
Outside of the ARM space, some of the CPU architectures still likely to be removed as no interest has been expressed yet in saving them include MMP, CNS3xxx, HISI, LPC18xx, Moxart, and MV78xx0.
