[Buildroot] [PATCHv2 1/4] linux: enable initrd/initramfs support when cpio rootfs is chosen

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2013-12-29 18:33 +0100, Thomas Petazzoni spake thusly:
> When one enables the generation of a cpio archive of the root
> filesystem, the most likely usage is as an initramfs for the
> kernel. This commit ensures that the kernel has initramfs support when
> the rootfs cpio image format is chosen.
> 
> This will for example ensure that if the user selects the ISO9660
> filesystem format (which uses a cpio initramfs), the kernel will have
> proper support to load and use the initramfs.
> 
> It is worth mentionning that when BR2_TARGET_ROOTFS_INITRAMFS is
> enabled, then BR2_TARGET_ROOTFS_CPIO is always enabled. That's why we
> move the enabling of CONFIG_BLK_DEV_INITRD from the initramfs case to
> the cpio case.
