X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f99c61a94ad11d401690a64ef83e152a098c850f;p=openwrt%2Fstaging%2Fzorun.git

procd: add 'platform_nand_pre_upgrade'

Add 'platform_nand_pre_upgrade' callback to allow platform specific
preparation right before flashinng, when already in ramdisk.

Example uses might be setting correct values for CI_{KERNPART,UBIPART}.
