The current Buildroot defconfigs for Raspberry Pi and Raspberry Pi 2
instantiate a console on tty1, which appears on HDMI. Add a console on
the serial port (ttyAMA0) to be more consistent with other defconfigs
and provide a better out-of-the-box experience to users used to have a
serial console from Buildroot defconfigs.
This requires three changes:
1. have two 'console=' entries in the kernel command line: tty1,
then ttyAMA0;
2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts
a getty on the last console= passed to the kernel, ttyAMA0;
3. add a new getty on tty1 to the generated inittab.
Step 2 is actually obtained by removing BR2_TARGET_GENERIC_GETTY_PORT
entirely from the defconfigs, since "console" is the default value.
Step 3 requires a post-build script since the Buildroot makefiles can
configure only one console.
Note: instead of simply adding a new getty on ttyAMA0 (which would
work) this patch actually changes BR2_TARGET_GENERIC_GETTY_PORT to
instantiate a console on UART, then adds back tty1 via
post-build.sh. This is done only to avoid the "GENERIC_SERIAL" comment
where we instantiate an HDMI console, then instantiate a really-serial
console on another line.
The result is these two inittab lines:
console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL
tty1::respawn:/sbin/getty -L tty1 0 vt100 # HDMI console

Since quite some time, the kernel and bootloader communities consider
zImage as the default format for kernel images on ARM, replacing
uImage. The load address information in uImage is no longer needed,
since the kernel is position-independent in terms of physical address,
except on a few old platforms. For most people, using zImage is simply
better/simpler, so let's switch to zImage as the default image format
on ARM.
All defconfigs are updated: 46 defconfigs no longer need to select
explicitly zImage because it's the default, and 16 defconfigs now need
to explicitly select uImage because that's no longer the default.

For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
- a standard upstream version string vX.Y.Z
- a non-standard version string, but still containg the standard X.Y.Z
Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.
There are a few cases were there was a mismatch:
- microzed: uses a 3.18 kernel, but 3.8 headers; fixed.
- xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
- zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.

Upstream has been playing evil-rebase on their tree, so they now
no longer have the changeset we are currently referencing.
They have now agreed to merge instead of rebasing:
https://github.com/raspberrypi/linux/issues/584
So, update the raspberrypi_defconfig to use a new changeset that
currently exists right _now_, in the hope it will not disapear in
the future (but we'll catch it pretty fast anyway, so we'll be able
to seriously bug up upstream in that case ;-) ).

Since commit 2a5cf5e (check kernel headers version), we also need to
specify the series of the custom kernel headers version.
The defconfigs file that define such a custom kernel headers version
now fail to build.
Add the required _AT_LEAST_X_Y options to those config files. Done with
this (convoluted but very fast, uch faster ythan manual editing!) rule:
for f in $( git grep -l BR2_DEFAULT_KERNEL_VERSION=\"3 ); do
grep -E '^BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_' "${f}" >/dev/null && continue
sed -r -e '/^(BR2_DEFAULT_KERNEL_VERSION="3\.([[:digit:]]+).*")$/s//\1\nBR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_\2=y/' "${f}"
done
Only kernels >= 3.0 need those options in the defconfig, since the
default for 2.6.x kernels is correct (selects _AT_LEAST_2_6), and
the default is not saved in a defconfig.
