H A Dmain.cdiff 182478 Sat Aug 30 14:11:39 MDT 2008 marius - Read ASI_{D,I}TLB_DATA_ACCESS_REG twice in order to work around
errata of USIII and beyond (USIII erratum #19, USIII+ erratum #1,
USIIIi erratum #1).
- Use the cheetah PA mask in {d,i}tlb_va_to_pa_sun4u() for USIII
and beyond. This is done so that these functions will still mask
the debug bits of spitfire-class CPUs once we increase TD_PA_BITS
to match the number of bits used for the PA by cheetah-class CPUs.
- Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the
context of the mappings entered. This is more or less cosmetic as
TLB_CTX_KERNEL is 0.
- Now that we have to distinguish between different sun4u CPUs in
the loader anyway, no longer do trial and error when reading the
portid property.
