-This directory contains a simple example of how one might
-start Go running on bare hardware. There is currently code
-for 386 and arm.
-
-
-386
-
-It is very primitive but can run go/test/sieve.go, the concurrent
-prime sieve, on a uniprocessor.
-
-To run, first build the tools by running all.bash with GOARCH=386
-and GOOS set to your normal GOOS (linux, darwin).  Then:
-
-	export GOOS=tiny
-	cd $GOROOT/src/pkg/runtime
-	make clean
-	make install
-	cd tiny
-	8g $GOROOT/test/sieve.go
-	8l sieve.8
-	8l -a sieve.8 >sieve.asm	# can consult sieve.asm for debugging
-	dd if=/dev/zero of=disk count=10000
-	cat bootblock 8.out | dd of=disk conv=notrunc
-
-Use the built-in print(text string) function to print to the
-console.
-
-
-BOCHS
-
-You may have to tweak the .bochsrc depending on your system,
-and you may need to install the Bochs emulator.
-
-    $ cp dot-bochsrc .bochsrc
-    $ $EDITOR .bochsrc # tweak it if required
-    $ bochs
-
-
-ORACLE xVM VIRTUALBOX
-
-Install VirtualBox. Then:
-
-    Build 'disk' (described above under '386').
-
-    $ VBoxManage convertfromraw disk go-tiny.vdi
-    $ VirtualBox
-        create a new VM; as disk use the go-tiny.vdi image.
-        start the vm.
-
-
-QEMU / KVM
-
-This should work the same for qemu and kvm (really: qemu-kvm).
-
-    Build 'disk' (described above under '386').
-
-    $ qemu -hda disk
-
-
-ARM
-
-First build the toolchain using GOARCH=arm and GOOS=linux. When
-you build your embedded code set GOARCH=tiny.
-
-	export GOOS=tiny
-	cd $GOROOT/src/pkg/runtime
-	make clean
-	make install
-
-On arm the tiny runtime doesn't define a low level write function. You can either
-define a stub if you don't need debug output, or more usefully, define it to
-print to some debug serial port. Here is a sample function that prints to
-the DBGU on an at91sam7s:
-
-#define DBGU_CSR  ((uint32*)   0xFFFFF214) // (DBGU) Channel Status Register
-#define US_TXRDY        ((uint32) 0x1 <<  1) // (DBGU) TXRDY Interrupt
-#define DBGU_THR  ((uint32*)   0xFFFFF21C) // (DBGU) Transmitter Holding Register
-
-int32
-write(int32 fd, void* b, int32 n)
-{
-	uint32 i;
-	uint8* s = (uint8*)b;
-
-	for (i = 0; i < n; i++) {
-		while ((*DBGU_CSR & US_TXRDY) == 0) {
-		}
-		*DBGU_THR = *s;
-		s++;
-	}
-	return n;
