-	 * Effects:	writes a single byte to pci config space
-	 *
-	 * Notes:	This routine is optimized for minimal register usage.
-	 *              And the tricks it does cannot scale beyond writing a single byte.
-	 *
-	 *              What it does is almost simple.
-	 *              It preserves %eax (baring special bits) until it is written
-	 *              out to the appropriate port.  And hides the data byte
-	 *              in the high half of edx.
-	 *
-	 *              In %edx[3] it stores the byte to write.
-	 *              In %edx[2] it stores the lower three bits of the address.

-1) Include llshell.inc in your northbridge Config file
-2) In raminit.inc (or whatever), make a jmp out to low_level_shell, setting
-   a return label in %esp.
-For example:
-ram_set_registers:
-
-	mov $llshell_ret1,%esp
-	jmp low_level_shell
-llshell_ret1:
-
-        /* Disable and invalidate the cache */
-        invd
-        mov %cr0, %eax
-        ....
-3) Optionally, comment out two lines in ramtest.inc:
-5:
-        CONSOLE_INFO_TX_STRING($rt_toomany)
-        // post_code(0xf1)
-        // jmp  .Lhlt
-otherwise, a ramtest failure will hang
-
-4) build and flash as normal
-If it worked, the speaker will beep, and you'll get a shell.
-Type help or ? at the prompt for a list of commands.
