Christian Lamparter e2b35f91b3 apm821xx: switch MR24's initramfs to multi-image method
The recent change to switch to gcc 7.3 broke the image
generation code, as the kernel would no longer fit into
KERNEL_SIZE.

This patch fixes the issue by reworking the initramfs
creation and packaging, which will get rid of the
KERNEL_SIZE check in the process.

This new initramfs can be loaded through the MR24 U-boot
in the following way:

=> setenv ipaddr 192.168.1.1
=> setenv bootargs console=ttyS0,$baudrate
=> tftpboot c00000 192.168.1.2:meraki_mr24-initramfs-kernel.bin
[...]
Load address: 0xc00000
Loading: ################################################ [...]
done
    Bytes transferred = 5952544 (5ad420 hex)
    => bootm $fileaddr
    \## Booting kernel from Legacy Image at 00c00000 ...
    ...

This is the buildsystem for the OpenWrt 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.
