- * Define a configuration structure to hold the board configuration.
- * Need to set this up in the code (for now) with the boards that are
- * to be configured into the system. This is what needs to be modified
- * when adding/removing/modifying boards. Each line entry in the
- * stl_brdconf[] array is a board. Each line contains io/irq/memory
- * ranges for that board (as well as what type of board it is).
- * Some examples:
- * { BRD_EASYIO, 0x2a0, 0, 0, 10, 0 },
- * This line would configure an EasyIO board (4 or 8, no difference),
- * at io address 2a0 and irq 10.
- * Another example:
- * { BRD_ECH, 0x2a8, 0x280, 0, 12, 0 },
- * This line will configure an EasyConnection 8/32 board at primary io
- * address 2a8, secondary io address 280 and irq 12.
- * Enter as many lines into this array as you want (only the first 4
- * will actually be used!). Any combination of EasyIO and EasyConnection
- * boards can be specified. EasyConnection 8/32 boards can share their
- * secondary io addresses between each other.
- *
- * NOTE: there is no need to put any entries in this table for PCI
- * boards. They will be found automatically by the driver - provided
- * PCI BIOS32 support is compiled into the kernel.
