Subject: Re: [PATCH RFC 04/10] ARM: cortina: Add support for the CS75xx SoC family
Date: Wed, 30 Sep 2026 07:08:21 +0000 [thread overview]

> The Cortina Systems CS75xx ("Goldengate G2") are network processors
> with two Cortex-A9 cores, an SCU, GIC, the Cortex-A9 global and private
> timers and a PL310 L2 cache controller. The CS7542 is used, among others,
> in the Securifi Almond+ router.
>
> The generic DT machine is sufficient for the platform, so only the SMP
> bring-up needs code: the bootloader parks the secondary core in a WFE
> loop that polls a global software register, so boot it by writing the
> physical address of secondary_startup to the register named by the
> cpu-release-addr property and issuing SEV.
>
> The CPU is a Cortex-A9 r2p1, so select the errata workarounds that apply
> to that revision and can be enabled on a multiplatform kernel. The PL310
> is r3p2 and needs none of the PL310 workarounds.
