Hi Randy,
Le sam., nov. 6 2021 at 10:49:32 -0700, Randy Dunlap <rdunlap@infradead.org> a écrit : > MIPS does not always provide clk*() interfaces and there are no > always-present stubs for them, so depending on "MIPS || COMPILE_TEST" > is not strong enough to prevent build errors. > > Likewise MACH_INGENIC_SOC || COMPILE_TEST is not strong enough > since if only COMPILE_TEST=y (with some other MIPS MACH_ or CPU or > BOARD setting), there are still the same build errors. > > It looks like depending on MACH_INGENIC_SOC is the only thing that is > sufficient here in order to prevent build errors.
Should be "depends on MACH_INGENIC". This symbol is selected when building a kernel tailored for Ingenic boards (CONFIG_MACH_INGENIC_SOC) and also selected when building a generic MIPS kernel that supports Ingenic SoCs (CONFIG_BOARD_INGENIC).
Cheers, -Paul
