rootfs part needs to be aligned to erase block size which is passed as
the 6th argument to Image/Build/Seama and is now 65536 since commit
commit 5119ee9 "ar71xx: fix bogus hardcoded kernel image size for Seama
images (fixes #20585)", but $(($(6) - 64)) still assumes that the
argument is a limit on kernel partition size, i.e. 1310720, so the
generated factory image is wrong in that the kernel will fail to find
the rootfs (FlySpray link at [1])
This patch will workaround it with the following steps
1. Calculate the required space for seama header and META data in step 5
2. Pre-padding 64 bytes to lzma-compressed loader
3. Generate correctly padded image-$(2).tmp
4. Strip out the padding
5. Seal it with seama utility
While at it convert seama to new build method
[1] FS#35 - mynet-n750 factory images don't find root partition,

This is the buildsystem for the LEDE Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your LEDE Community http://www.lede-project.org
