[linux-yocto] [linux-yocto v5.2] Add the support for the Marvell cn96xx SoC

[Kevin Hao]

Hi Bruce,

This patch series adds the kernel and kernel meta for the support of the
Marvell cn96xx SoC support. These patches are almost the same as what I
have sent for the linux-yocto-dev [1] [2]. The major difference between
them is that the BPHY driver is added. The BPHY driver handles ioctl to
set/clear irq handlers in EL3 using SMC calls. The purpose of this is to
handle some BPHY interrupts in userspace directly. In order to support this,
we have to make some ugly hack to some core files like arch/arm64/mm/context.c
or arch/arm64/mm/context.c, but the change is pretty simple and are protected
with the specific kernel option.
