This new version adds support for early NCR chips.
53C810 non 'A', 53C815 and 53C825 non 'A' are now attached by the driver (by default). The driver uses a different SCRIPTS set based on MEMORY MOVE instructions for these chips. 2 SCRIPTS sets (firmwares) numbered #1 and #2 are used for the whole support of the 53C8XX family to get possible: - FW #1 : Only based on MEMORY MOVE instructions. Selected for 810, 815, 825. - FW #2 : LOAD/STORE based. This is the firmware also used by previous driver versions. Selected for other chips. When both `ncr' and `sym' are configured, `sym' will now attach all the 53C8XX devices by default. Previous balancing between `ncr' and `sym' can be preserved by: - Either editing sym_conf.h and commenting the following compile option: #define SYM_CONF_GENERIC_SUPPORT (This also saves about 3.5Kb of kernel memory). - Or setting kernel config option SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)
