Broadcom Swarm support

[Aurelien Jarno <aurelien@aurel32.net>]

Hi all,

I am still trying to get a Broadcom Swarm boot on a recent kernel. I
have made some progress, but I am now stuck on another problem.

I am using a lmo 2.6.30 kernel, using the defconfig configuration, with
minor tweaks to get the IDE and EXT3 support working.

The boot process works correctly until it reaches userland:

| hda: max request size: 128KiB
| hda: 78165360 sectors (40020 MB) w/2048KiB Cache, CHS=65535/16/63
| hda: cache flushes not supported
|  hda: hda1 hda2
| eth0 (sb1250-mac): not using net_device_ops yet
| sb1250-mac.0: registered as eth0
| eth0: enabling TCP rcv checksum
| eth0: SiByte Ethernet at 0x10064000, address: 00:02:4c:fe:51:e0
| eth1 (sb1250-mac): not using net_device_ops yet
| sb1250-mac.1: registered as eth1
| eth1: enabling TCP rcv checksum
| eth1: SiByte Ethernet at 0x10065000, address: 00:02:4c:fe:51:e1
| usbmon: debugfs is not available
| ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
| TCP cubic registered
| NET: Registered protocol family 17
| NET: Registered protocol family 15
| RPC: Registered udp transport module.
| RPC: Registered tcp transport module.
| kjournald starting.  Commit interval 5 seconds
| EXT3-fs: mounted filesystem with writeback data mode.
| VFS: Mounted root (ext3 filesystem) readonly on device 3:2.
| Freeing unused kernel memory: 184k freed
| Kernel panic - not syncing: Attempted to kill init!
| Rebooting in 5 seconds..Passing control back to CFE...

This is with /sbin/init, but I get the exact same problem with /bin/sh.
Also the file is found, as otherwise the message is different. The same
partition when used with an older kernel (2.6.18) works perfectly.

I have the problem with both big and little endian, and with and without
SMP support.

Does anyone is able to run a recent kernel on such a board ? If yes,
could you please share the configuration file? Thanks in advance.

Best regards,
Aurelien
