Subject: x86: Adjust section placement in AMD northbridge related code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=691269f0d918cd72454c254f97722f194c07b9a8;p=openwrt%2Fstaging%2Fblogic.git

x86: Adjust section placement in AMD northbridge related code

amd_nb_misc_ids[] can live in .rodata, and enable_pci_io_ecs()
can be moved into .cpuinit.text.
