Update the kernel configuration to support modern storage stacks required for ISO booting on x86_64. The transition from 4.19 to 6.18 requires explicit activation of: - CONFIG_PCI: To discover the emulated IDE/SATA controllers. - CONFIG_ATA & CONFIG_ATA_PIIX: Modern libATA drivers for QEMU's chipset (replacing the legacy IDE subsystem). - CONFIG_SCSI & CONFIG_BLK_DEV_SR: Necessary to handle the CD-ROM as a SCSI device (/dev/sr0), which is mandatory for ISO9660. Without these options, the kernel cannot locate or mount the rootfs from the ISO image. Signed-off-by: Dowan Gullient <dowan.gullient@smile.fr> Signed-off-by: Julien Olivain <ju.o@free.fr>
