PXA255 stepping...
Hi all...
Can anyone explain me what is stepping in the pxa255 processor...
?? here are some comments from my bootloader code...
--------------------------------------------------------------------------
Workaround for early termination of SDRAM autorefresh on exit from
;; processor's sleep state in B1 stepping of XPA250/210. (sighting 27004)
;; Need first forced refresh within 8 usec.
Notes: - MMU assumed to be inactive at this time, so use physical addresses
;; - Eboot didn't boot on A1 stepping without the leading exclusion,
;; so the core code must be restricted to B1 only.
