It helps having a defconfig that works fine out of the box for most Kirkwood platforms.

Hi Jason mvebu_v5_defconfig is a single platform build, since kirkwood is the only mvebu v5 device. In future orion5x could be added, but i don't expect a huge build time difference.

Ok, just make kirkwood_defconfig removal a separate patch so we can revert it later if we want. thx, Jason. ^ permalink raw reply [flat|nested] 8+ messages in thread

Hi Jason How would that work exactly, without having mach-kirkwood? Andrew ^ permalink raw reply [flat|nested] 8+ messages in thread

Set ARCH_MVEBU, MACH_KIRKWOOD, unset ARCH_MULTI_V5 and adjust the Kconfig to allow such a scenario. It may not be desirable right now, but having it as a separate patch doesn't hurt anything, and it keeps the door open to the possibility in the future. thx, Jason. ^ permalink raw reply [flat|nested] 8+ messages in thread
