All architecures use memblock for early memory management. There is no need
for the CONFIG_HAVE_MEMBLOCK configuration option.

Hi Mike,

A minor editing issue in here that is stopping boot on arm64 platforms with latest
version of the mm tree.  

Can you please try the following patch:


From 079bd5d24a01df3df9500d0a33d89cb9f7da4588 Mon Sep 17 00:00:00 2001

Subject: [PATCH] of/fdt: fixup #ifdefs after removal of HAVE_MEMBLOCK config
 option

The removal of HAVE_MEMBLOCK configuration option, mistakenly dropped the
wrong #endif. This patch restores that #endif and removes the part that
should have been actually removed, starting from #else and up to the
correct #endif

Hi Mike,

That's identical to the local patch I'm carrying to fix this so looks good to me.

For what it's worth given you'll probably fold this into the larger patch.

Tested-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Well, this is up to Andrew now, as the broken patch is already in the -mm
tree.
 

Thanks for the quick reply.

Jonathan
