- *       FUNCTIONAL DESCRIPTION:
- * This routine is called to autodetect the geometry of the DRAM.
- *
- * This routine is called to determine the number of column bits for the DRAM
- * devices in this external bank. This routine assumes that the external bank
- * has been configured for an 11-bit column and for 4 internal banks. This gives
- * us the maximum address reach in memory. By writing a test value to the max
- * address and locating where it aliases to, we can determine the number of valid
- * column bits.
- *
- * This routine is called to determine the number of internal banks each DRAM
- * device has. The external bank (under test) is configured for maximum reach
- * with 11-bit columns and 4 internal banks. This routine will write to a max
- * address (BA1 and BA0 = 1) and then read from an address with BA1=0 to see if
- * that column is a "don't care". If BA1 does not affect write/read of data,
- * then this device has only 2 internal banks.
- *
- * This routine is called to determine the ending address for this external
- * bank of SDRAM. We write to a max address with a data value and then disable
- * row address bits looking for "don't care" locations. Each "don't care" bit
- * represents a dividing of the maximum density (128M) by 2. By dividing the
- * maximum of 32 4M chunks in an external bank down by all the "don't care" bits
- * determined during sizing, we set the proper density.
- *
- * WARNINGS.
- * bp must be preserved because it is used for return linkage.
- *
- * EXIT
- * nothing returned - but the memory subsystem is enabled
