QUALCOMM JNAND DRIVER

;============================================================================
;  Name:
;    JNAND_MSM_INIT.CMM  for Saber
;
;  Description:
;    Script to initialize the MSM for JNAND program to run.  No h/w init
;    is done in JNAND
;
;  Execution:
;    Called by jnand.cmm and jnandtest.cmm to init the MSM

; 10/30/03   drh     Save current directory so we can return to it.
; 07/28/03   drh     Minor cosmetic cleanup, no functional changes
; 07/23/03    sr     Added call to setupgpll.cmm as a workaround for enabling
;                    searcher RAM after power UP. Also changed script to run
;                    common .cmm files like constants.cmm, setupebi2.cmm, 
;                    setupmemmap.cmm and setupxmemc.cmm from build/ms directory
; 07/08/03   drh     Integrate change by dl to turn off camera flash
;                    Remove erroneous error message
; 06/10/03   drh     Saber - taken from Jaguar jnand_msm_init.cmm

; 07/05/02   drh     Created - taken from Cougar JFINIT.CMM directly with
;                    minor changes to account for NAND
