Hello,
This bunch of patches adds support to autoload IP module drivers when they are
detected by the ipack bus driver.
Also, it changes the endianness of the carrier device to Big Endian as it is
defined in the Industry Pack standard. Due to that, the source code is
simplified too.
There are mo

Hi Rusty,
I used libsparse and kernel source annotations to check that code uses

Add a simple cpio decoder without library dependencies for the purpose
of extracting components from the initramfs blob for early kernel
