20070415	Landisk PCLOCK should be 33.33 MHz, not 50 MHz. (This makes
		the clock run at correct speed.)
		FINALLY found and fixed the bug which caused OpenBSD/landisk
		to randomly bug out: an &-sign was missing in the special case
		handling of FPSCR in the 'LDS.L @Rm+,FPSCR' instruction.
		Adding similar special case handling for 'LDC.L @Rm+,SR'
		(calling sh_update_sr() instead of just loading).
		Implementing the 'FCNVSD FPUL,DRn' and 'FCNVDS DRm,FPUL'
		SuperH instructions.
		The 'LDC Rm,SR' instruction now immediately breaks out of the
		dyntrans loop if an interrupt is to be triggered.
20070416	In memory_rw.c, if mapping a page as writable, make sure to
		invalidate code translations even if the data access was a
		read.
		Minor SuperH updates.
20070418	Removing the dummy M68K emulation mode.
		Minor SH update (turning unnecessary sts_mach_rn, sts_macl_rn,
		and sts_pr_rn instruction handlers into mov_rm_rn).
20070419	Beginning to add a skeleton for an M88K mode: Adding a hack to
		allow OpenBSD/m88k a.out binaries to be loaded, and disassembly
		of a few simple 88K instructions.
		Commenting out the 'LDC Rm,SR' fix from a few days ago, because
		it made Linux/dreamcast bug out.
		Adding a hack to dev_sh4.c (an extra translation cache
		invalidation), which allows OpenBSD/landisk to boot ok after
		an install. Upgrading the Landisk machine mode to stable,
		updating documentation, etc.
20070420	Experimenting with adding a PCI controller (pcic) to dev_sh4.
		Adding a dummy Realtek 8139C+ skeleton device (dev_rtl8139c).
		Implementing the first M88K instructions (br, or[.u] imm), and
		adding disassembly of some more instructions.
20070421	Continuing a little on dev_rtl8139c.
20070422	Implementing the 9346 EEPROM "read" command for dev_rtl8139c.
		Finally found and fixed an old bug in the log n symbol search
		(it sometimes missed symbols). Debug trace (-i, -t etc) should
		now show more symbols. :-)
20070423	Continuing a little on M88K disassembly.
20070428	Fixing a memset arg order bug in src/net/net.c (thanks to
		Nigel Horne for noticing the bug).
		Applying parts of a patch from Carl van Schaik to clear out
		bottom bits of MIPS addresses more correctly, when using large
		page sizes, and doing some other minor cleanup/refactoring.
		Fixing a couple of warnings given by gcc with the -W option (a
		few more warnings than just plain -Wall).
		Reducing SuperH dyntrans physical address space from 64-bit to
		32-bit (since SH5/SH64 isn't imlemented yet anyway).
		Adding address-to-symbol annotation to a few more instructions
		in the SuperH instruction trace output.
		Beginning regression testing for the next release.
		Reverting the value of SCIF_DELAYED_TX_VALUE from 1 to 2,
		because OpenBSD/landisk may otherwise hang randomly.
20070429	The ugly hack/workaround to get OpenBSD/landisk booting without
		crashing does NOT work anymore (with the April 21 snapshot
		of OpenBSD/landisk). Strangely enough, removing the hack
		completely causes OpenBSD/landisk to work (!).
		More regression testing (re-testing everything SuperH-related,
		and some other things).
		Cobalt interrupts were actually broken; fixing by commenting
		out the DEC21143s in the Cobalt machine.
20070430	More regression testing.
20070501	Updating the OpenBSD/landisk install instructions to use
		4.1 instead of the current snapshot.
		GAAAH! OpenBSD/landisk 4.1 _needs_ the ugly hack/workaround;
		reintroducing it again. (The 4.1 kernel is actually from
		2007-03-11.)
		Simplifying the NetBSD/evbarm install instructions a bit.
		More regression testing.
