cater for odyssey ocmb chipop for dump and ffdc
Browse files Browse the repository at this point in the history 
1) Modify backend dts file to add fsi targets as they
are used as part of getting ffdc

2) Added new chipop for odyssey target which caters for
dump and ffdc

Tested
get_backend_target class_name chipop-ody ocmb_proc 0 ocmb_index 3
get_backend_target class_name fsi-ody ocmb_proc 0 ocmb_index 3
get_backend_target class_name chipop-ody ocmb_proc 0 ocmb_index 3
**sucessfully collected dump data len is 20184
before calling sbe_ody_ffdc_get
PDBG:fsi_ody_read[382]: rc = 0, addr = 0x02809, data = 0x9133603f, target = /hmfsi-ody@111
**status of ffdc_get is 0 ffdc_len 0
