Hello! This patchset adds support for 32-bit Meson A1 board.
Hi Alexev, I'm aware Amlogic also runs their kernel as 32bit to gain a few kbytes of memory, but those processors are ARMv8 and the arm64 arch code has been designed for those CPUs. So far I didn't find a single good reason to add 32bit support for ARMv8 Amlogic based SoCs, if you have a solid reason please share. And as Krzysztof stated, the support is incomplete and cannot work without a dts file. Neil
We describe device tree with following components: CPU, GIC, IRQ, Timer, UART, PIN controller. It's capable of booting up into the serial console. We have tested this DTS and used drivers at our 32-bit Meson A1 board and it works correctly.
