Hi, Overview ======== Let's continue the removal of old platforms. We already get rid of Exynos4212. Now it's time for Exynos5440. The Exynos5440 (quad-core A15 with GMAC, PCIe, SATA) was targeting server platforms but it did not make it to the market really. There are no development boards with it and probably there are no real products neither. The development for Exynos5440 ended in 2013 and since then the platform is in maintenance mode. The only development happening around it is the PCIe driver for Exynos5433 (ARMv8). [1] Removing Exynos5440, makes our life slightly easier: 1. Less maintenance, 2. Smaller code, less quirks, 3. No need to preserve (imaginary) backward-compatibility for Exynos PCIe driver (so it is easier to add support for Exynos5433). Because of point (3) above - I left the PCIe and PCIe PHY drivers intact. Dependencies ============ I think about starting with removal of DTS in some kernel release (patch 1/10). Then all drivers can be removed/updated - subsystem maintainers can pick their patches freely. Finally, after getting rid of all Exynos5440 symbols, the last patch (10/10) will end in arm-soc tree. Any comments?
