| 173 | * |
| 174 | * The 'dummy' variable is used to increment the MAD. 'dummy' is |
| 175 | * supposed to be a pointer to the memory of the device being |
| 176 | * programmed by the UPM. The data in the MDR is written into |
| 177 | * memory and the MAD is incremented every time there's a read |
| 178 | * from 'dummy'. Unfortunately, the current prototype for this |
| 179 | * function doesn't allow for passing the address of this |
| 180 | * device, and changing the prototype will break a number lots |
| 181 | * of other code, so we need to use a round-about way of finding |
| 182 | * the value for 'dummy'. |
| 183 | * |
| 184 | * The value can be extracted from the base address bits of the |
| 185 | * Base Register (BR) associated with the specific UPM. To find |
| 186 | * that BR, we need to scan all 8 BRs until we find the one that |
| 187 | * has its MSEL bits matching the UPM we want. Once we know the |
| 188 | * right BR, we can extract the base address bits from it. |
| 189 | * |
| 190 | * The MxMR and the BR and OR of the chosen bank should all be |
| 191 | * configured before calling this function. |
| 192 | * |
| 193 | * Parameters: |
| 194 | * upm: 0=UPMA, 1=UPMB, 2=UPMC |
| 195 | * table: Pointer to an array of values to program |
| 196 | * size: Number of elements in the array. Must be 64 or less. |
