Hello, all. I've been able to boot Linux on my raspberry pi, after
fixing several bugs in loader. But for this I had to have a line like:
linux /kernel_cutdown.img dma.dmachans=0x???? bcm2708_fb.fbwidth=656
bcm2708_fb.fbheight=416 bcm2708.boardrev=0xe bcm2708.serial=0x????????
smsc95xx.macaddr=??:??:??:??:?? dwc_otg.lpm_enable=0
console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait
When using standard bootloader the part
dma.dmachans=0x???? bcm2708_fb.fbwidth=656 bcm2708_fb.fbheight=416
bcm2708.boardrev=0xe bcm2708.serial=0x????????
smsc95xx.macaddr=??:??:??:??:??
is added automatically. The part
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200
console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait
comes from cmdline.txt.
It's not possible to tell for sure then one ends and the other starts.
Does anyone see any problem with prepending the arguments GRUB itself
received to the kernel command line on all platforms using ATAGs?
