That'd be great. I can switch over to a proper defconfig then and not
jump through extra hoops to build test patches.

Also, I'm seeing a bunch of weird errors from building MIPS, mostly
things like this:

	  CC      net/ipv4/netfilter/arp_tables.mod.o
	{standard input}: Assembler messages:
	{standard input}: Warning: .gnu_attribute 4,3 requires `softfloat'

or this later on:

	mips-linux-gnu-ld: Warning: vmlinuz uses -mhard-float (set by arch/mips/boot/compressed/head.o), arch/mips/boot/compressed/decompress.o uses -msoft-float

This is essentially a gpr_defconfig (because it select MIPS_ALCHEMY,
which in turns pulls in COMMON_CLK that PWM_IMG depends on) and then
enabling MFD_SYSCON on top so that all dependencies are met.

What am I doing wrong?
