I don't know what's them compile? Does means 'the driver has public driver, so any arch will compile it'?

Today it does compile on all archs

If so, the compile qdma module need enable config options 'CONFIG_FSl_QDMA' and other architecture should be hide the options. The driver supported arm or arm64 arch, If I change Kconfig to solve compile issues, Can I do that?

yes but as a last resort, it would still help if driver has no dependency on arch and is able to compile on others..

Hi,

I want to do the same, but I can only verify in x86/x86_64, arm/arm64 and powerpc.

For now, the issues is ioread32/64 ioread32/64be and iowrite32/64 iowrite32/64be depends on arch defined. most arch defined it, but other not defined(such as x86,s390..).

do you have any good ideas?
