IBM PowerPC 405GP Rev. E (rev register ID is 0x40110145).
The register descriptions of OPBA0_CR and OPBA0_PR confusing me: OPBA0_CR
resides at MMIO location 0xEF60'0600 and OPBA0_PR at 0xEF60'0601. Both are
described as two 32 bit registers, but only using the upper 8 bits.
I think I have to access these registers only byte wide at their locations
0xEF60'0600 and 0xEF60'0601, or both in one 16 bit access at 0xEF60'0600.
Right?
Best regards,
Juergen Beisert
