................ +=> +------------------------------------------------------------------------------ + + +Patch per Mon, 06 Aug 2001 17:57:27: + +- upgraded Flash support (added support for the following chips: + AM29LV800T/B, AM29LV160T/B, AM29DL322T/B, AM29DL323T/B) +- BCR tweakage for the 8260 bus mode +- SIUMCR tweakage enabling the MI interrupt (IRQ7) + +To simplify switching between the bus modes, a new configuration +option (CONFIG_BUSMODE_60x) has been added to the "config_TQM8260.h" +file. If it is defined, BCR will be configured for the 60x mode, +otherwise - for the 8260 mode. + +Concerning the SIUMCR modification: it's hard to predict whether it +will induce any problems on the other (60x mode) board. However, the +problems (if they appear) should be easy to notice - if the board +does not boot, it's most likely caused by the DPPC configuration in +SIUMCR. |
