I have dug a little more, and if I well understand, the
initramfs_data.cpio.gz should be
expanded from __initramfs_start (defined in vmlinux.lds.S)
But when and how is it done?
And by who?
Architecture specific code? bootloader, or setup_arch() memory
initialisation function?
Or the kernel itself and automatically during kernel build? Or during boot?
In my case, the initramfs_data.cpio.gz is not present at __initramfs_start.
When the kernel tries to find the compression magic number
("decompress_method() function),
it complains and panic with the following message:
kernel panic: junk in compressed archive
(I precise that I am porting Linux-2.6.37 to a new architecture)
Thanks in advance for your help and advices.
