+PowerPC emulation status.
+The goal of this file is to provide a reference status to avoid regressions.
+
+===============================================================================
+PowerPC core emulation status
+
+INSN: instruction set.
+ OK => all instructions are emulated
+ KO => some insns are missing or some should be removed
+ ? => unchecked
+SPR: special purpose registers set
+ OK => all SPR registered (but some may be fake)
+ KO => some SPR are missing or should be removed
+ ? => unchecked
+MSR: MSR bits definitions
+ OK => all MSR bits properly defined
+ KO => MSR definition is incorrect
+ ? => unchecked
+IRQ: input signals definitions (mostly interrupts)
+ OK => input signals are properly defined
+ KO => input signals are not implemented (system emulation does not work)
+ ? => input signals definitions may be incorrect
+MMU: MMU model implementation
+ OK => MMU model is implemented and Linux is able to boot
+ KO => MMU model not implemented or bugged
+ ? => MMU model not tested
+EXCP: exceptions model implementation
+ OK => exception model is implemented and Linux is able to boot
+ KO => exception model not implemented or known to be buggy
+ ? => exception model may be incorrect or is untested

+- Gentoo Linux live CDROM 1.4 - boots, compiles linux kernel
+- Debian Linux woody - boots from CDROM and HDD
+- Mandrake Linux 9 - boots from CDROM, freezes during install
+- Knoppix 2003-07-13_4 boots from CDROM, pb with X configuration
+ distribution bug: X runs with a properly hand-coded configuration.

+
+* Linux 2.6 support seems deadly broken (used to boot...).
+
+* PowerPC 405EP reference boards:
+- can boot Linux 2.4 & 2.6.
+ Need to provide a flash image ready to boot for reproductible tests.
+
