* ich_descriptors.c Invert the meaning of 'dual_output' bitWerner Zeh2022-02-161-1/+1
| | | | | | | | | | | | | | | | | | In the Flash Component description register (FLCOMP) bit 30 reports the capability of using dual output for fast read operation on the flash component. According to various SPI Programming Guides (checked for Panther Point, Lewisburg C620, Apollo Lake and Elkhart Lake) the dual output is enabled when this bit is set and disabled if not. Currently the logic displays it the other way around when parsing the descriptor. This patch changes this so now if bit 30 in FLCOMP is not set, dual read support for fast read operation is shown as disabled.

Add a new enum CHIPSET_500_SERIES_TIGER_POINT and treat it identically to CHIPSET_400_SERIES_COMET_POINT. There are some exceptions though, ICCRIBA is no longer present n descriptor content so a new union has been defined for new fields and used in descriptor guessing. freq_read field is not present on Tiger Lake, moreover in CannonPoint and Comet Point this field is used as eSPI/EC frequency, so a new function to print read frequency has ben added. Finally Tiger lake boot straps include eSPI, so a new bus has been added for the new straps.
