[LEDE-DEV] [PATCH 2/2] ipq806x: Add support for ipq40xx subtarget

[Ram Chandra Jangir]

Hi Felix,

> What's the reason for making it a separate subtarget?

We would like to add ipq40xx as subtarget for following reasons.
1. ipq40xx is different SoC than existing ipq806x
2. Would like to have SoC specific images, so that kernel configs can be tweaked per SoC
3. SoC specific images will be smaller in size & faster boot-time
4. Newer SoC may have exclusive FWs which needs compile time differentiation.
5. There is new SoC(ipq807x) under development, which is based on ARMv8. Hence we will need subtarget approach to accommodate new SoC.

Thanks,
Ram

What's the reason for making it a separate subtarget?
I think it would be better to be able to run ipq806x and ipq40xx from the same build. It also saves resources for our snapshot builds.
