cur_ppc_sys_spec is NULL
I have latest linux-2.6-denx (MPC8272ADS board) kernel and I have some questions, may be somebody knows:
Here is the kernel output
Linux version 2.6.14-rc3-g2f70d4fe ..
Motorola PQ2 ADS PowerPC port
Built 1 zonelists
Kernel command line: console=ttyCPM0,115200 /dev/ram rw
PID hash table entries: 512 (order: 9, 8192 bytes)
Warning: real time clock seems stuck!
Dentry cache hash table entries: 16384 (order: 4, 65536 bytes) Inode-cache hash table entries: 8192 (order: 3, 32768 bytes)
Memory: 62720k available (1628k kernel code, 388k data, 92k init, 0k highmem) Mount-cache hash table entries: 512
NET: Registered protocol family 16
<stuck here>
Using gdb and BDI2000 I have allocated the problem in ppc_sys_init(void) - cur_ppc_sys_spec is NULL. There are 3 functions to find an appropriate
spec:identify_ppc_sys_by_ididentify_ppc_sys_by_nameidentify_ppc_sys_by_name_and_id
None of them are called by pq2ads.c or from any other place for 8272. I am just wondering if anybody might know at what stage spec should be selected for 8272ADS?
Thank you,
Dimitry

Yes, that's just the point, and I know about this issue. One of those do need to be called early in the board initialization code. I'll come with the fix shortly (hopefully today).
