The following patches are dropped because they are merged upstream: -0001-tty-serial-drop-QCA-pecific-SoC-symbols.patch -0006-usb-drop-deprecated-symbols.patch -0009-MIPS-ath79-add-lots-of-missing-registers.patch -0010-MIPS-ath79-add-support-for-QCA953x-QCA956x-TP9343.patch -0014-MIPS-ath79-finetune-cpu-overrides.patch -0015-MIPS-ath79-enable-uart-during-early_prink.patch -0016-MIPS-ath79-get-PCIe-controller-out-of-reset.patch This patch is dropped due to the introduction of spi-mem framework: -461-spi-ath79-add-fast-flash-read.patch Thank to Michael Marley @mamarley for his work on this patch: -910-unaligned_access_hacks.patch Signed-off-by: Chuanhong Guo <gch981213@gmail.com> [synchronized kernel config with make kernel_oldconfig] Signed-off-by: Petr Štetiar <ynezz@true.cz>
