4 The CDS family of boards consists of a PCI backplane called the
5 "Arcadia", a PCI-form-factor carrier card that plugs into a PCI slot,
6 and a CPU daughter card that bolts onto the daughter card.

22     gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a)
26 ----------
28 The memory map for U-Boot and linux has been extended w.r.t. the ADS
29 platform to allow for utilization of all 85xx CDS devices.  The memory
30 map is setup for linux to operate properly.  The linux source when
31 configured for MPC85xx CDS has been updated to reflect the new memory

87 After copying the image into the second bank of flash, be sure to toggle
88 SW2[2] on the carrier card before resetting the board in order to set the
89 secondary bank as the boot-bank.

98 user-settable switches on the carrier board are used to configure

114 connected..  By convention, the user-specific bits of SW2 are used to
