[PATCH 0/2] Update poky-tiny to linux-yocto-tiny_3.4 for qemux86

[PATCH 0/2] Update poky-tiny to linux-yocto-tiny_3.4 for qemux86

[Darren Hart]

As these patches are dependent on eachother, sending to both poky and oe-core
lists. Flame away.

The refresh to 3.4 for tiny is coming in rather late as I was focused on other
BSPs. However, qemux86 has been at 3.4 for poky and linux-yocto for a while now.
This update effectively uses a subset of that tested config for the images built
with poky-tiny. This only impacts qemux86 on poky-tiny.  That configuration
builds and boots to the serial console.

NOTE: This kernel recipe is pending a minor meta-data change to the
linux-yocto_3.4 git repository which will require a SRCREV_meta update. That
update can be made to only the linux-yocto-tiny_3.4 recipe in order to minimize
risk to the rest of the system. However, please do not commit this until the
meta-data patch goes in. At that point I will update the branch with the new
SRCREV and notify the list in response to this email.

[PATCH 1/2] linux-yocto-tiny: Add tiny recipe for the 3.4 linux-yocto kernel

[Darren Hart]

This recipe builds the "tiny" kernel type defined by the linux-yocto
meta-data. Support is defined for the qemux86 machine via
common-pc-tiny.scc in the linux-yocto meta branch. The resulting
kernel is 1.8 MB and boots to a serial console with with qemux86 and
core-image-minimal using the following command:

qemu -kernel tmp/deploy/images/bzImage-qemux86.bin -initrd tmp/deploy/images/core-image-minimal-qemux86.cpio.gz -append "root=/dev/ram0 console=ttyS0" -nographic

[PATCH 2/2] poky-tiny: Update the default kernel to linux-yocto-tiny_3.4

[Darren Hart]

The 3.4 linux-yocto-tiny kernel successfully boots to a prompt for
qemux86.

The necessary changes have been committed to linux-yocto-3.4.git. I have
updated the branch with the appropriate SRCREV_meta for
linux-yocto-tiny_3.4.bb. These patches are ready to pull.
