Subject: [POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=edc164d18f6b86b6de134d432de286e6c440c66d;p=openwrt%2Fstaging%2Fblogic.git

[POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32

Now that we have a proper variable that is the address of the top
of low memory we can use it to limit the lmb allocations.
