Subject: [PATCH 00/10] ARM: sunxi: Add support for the Allwinner A31 SoC
Date: Tuesday 23rd July 2013 22:25:02 UTC (over 4 years ago)
Hi everyone, This patchset add support in Linux for the Allwinner A31 SoC. This SoC is the current high-end Allwinner SoC, and is powered by 4 Cortex-A7. SMP support is not there yet, but should come eventually, so does the clock support. As usual, since we don't have any storage device driver yet, it only boots from an initramfs. Finally, something worth mentionning is that with the current bootloader, you'll encounter 2 ~6s hangs during the boot. This is because the SMP bit of the Cortex-A7 doesn't appear to be set, leading to the CPU caches being disabled. This can partially be addressed by selecting CONFIG_SMP, that will remove the second hang, because the SMP bit is set after kernel decompression. Obviously, this won't remove the first hang that happens during decompression, but it's better than nothing. A proper fix would be to fix the bootloader.
