+
+Tastaturabfrage:
+
+Die Implementierung / Decodierung beruht auf den Angaben aus dem Do-
+kument "PIC LWE-Tastatur" in der Fassung vom 9. 3. 2001, insbesonde-
+re Tabelle 3 im Kapitel 4.3 Tastencodes. In U-Boot werden die vom
+Keyboard-Controller gelesenen Daten hexadezimal codiert in der auto-
+matisch angelegten Environment-Variablen "keybd" übergeben. Ist kei-
+ne Taste gedrückt worden, steht dort:
+
+ keybd=000000000000000000
+
+Der decodierte Tastencode ("keybd") kann mit den "bootargs" an den
+Linux-Kernel übergeben und dort z. B. in einem Device-Treiber oder
+einer Applikation ausgewertet werden.
+
+
+Sonderfunktionen beim Booten:
+
+Es lassen sich eine oder mehrere (beliebig viele) Tasten oder Tasten-
+kombinationen definieren, die Sonderfunktionen auslösen, wenn diese
+Tasten beim Booten (Reset) gedrückt sind.
+
+Wird eine eingestellte Taste bzw. Tastenkombination erkannt, so wird
+in U-Boot noch vor dem Start des "Countdown" und somit vor jedem an-
+deren Kommando der Inhalt einer dieser Taste bzw. Tastenkombination
+zugeordneten Environment-Variablen ausführen.
+
+
+Die Environment-Variable "magic_keys" wird als Liste von Zeichen ver-
+standen, die als Suffix an den Namen "key_magic" angefügt werden und
+so die Namen der Environment-Variablen definieren, mit denen die
+Tasten (-kombinationen) festgelegt werden:
+
+Ist "magic_keys" NICHT definiert, so wird nur die in der Environment-
+Variablen "key_magic" codierte Tasten (-kombination) geprüft, und
+ggf. der Inhalt der Environment-Variablen "key_cmd" ausgeführt (ge-
+nauer: der Inhalt von "key_cmd" wird der Variablen "preboot" zugewie-
+sen, die ausgeführt wird, unmittelbar bevor die interaktive Kommando-
+interpretation beginnt).
+
+Enthält "magic_keys" z. B. die Zeichenkette "0123CB*", so werden
+nacheinander folgende Aktionen ausgeführt:
+
+ prüfe Tastencode ggf. führe aus Kommando
+ in Variable in Variable
+ -----------------------------------
+ key_magic0 ==> key_cmd0
+ key_magic1 ==> key_cmd1
+ key_magic2 ==> key_cmd2
+ key_magic3 ==> key_cmd3
+ key_magicC ==> key_cmdC
+ key_magicB ==> key_cmdB
+ key_magicA ==> key_cmdA
+ key_magic* ==> key_cmd*
+
+Hinweis: sobald ein aktivierter Tastencode erkannt wurde, wird die
+Bearbeitung abgebrochen; es wird daher höchstens eines der definier-
+ten Kommandos ausgeführt, wobei die Priorität durch die Suchreihen-
+folge festgelegt wird, also durch die Reihenfolge der Zeichen in der
+Varuiablen "magic_keys".
+
+
+Die Codierung der Tasten, die beim Booten gedrückt werden müssen, um
+eine Funktion auszulösen, erfolgt nach der Tastaturtabelle.
+
+Die Definitionen
+
+ => setenv key_magic0 3a+3b
+ => setenv key_cmd0 setenv bootdelay 30
+
+bedeuten dementsprechend, daß die Tasten mit den Codes 0x3A (Taste
+"F1") und 0x3B (Taste "F2") gleichzeitig gedrückt werden müssen. Sie
+können dort eine beliebige Tastenkombination eintragen (jeweils 2
+Zeichen für die Hex-Codes der Tasten, und '+' als Trennzeichen).
+
+Wird die eingestellte Tastenkombination erkannt, so wird in U-Boot
+noch vor dem Start des "Countdown" und somit vor jedem anderen Kom-
+mando das angebene Kommando ausgeführt und somit ein langes Boot-
+Delay eingetragen.
+
+Praktisch könnten Sie also in U-Boot "bootdelay" auf 0 setzen und
+somit stets ohne jede User-Interaktion automatisch booten, außer,
+wenn die beiden Tasten "F1" und "F2" beim Booten gedrückt werden:
+dann würde ein Boot-Delay von 30 Sekunden eingefügt.
+
+
+Hinweis: dem Zeichen '#' kommt innerhalb von "magic_keys" eine beson-
+dere Bedeutung zu: die dadurch definierte Key-Sequenz schaltet den
+Monitor in den "Debug-Modus" - das bedeutet zunächst, daß alle weite-
+ren Meldungen von U-Boot über das LCD-Display ausgegeben werden;
+außerdem kann man durch das mit dieser Tastenkombination verknüpfte
+Kommando z. B. die Linux-Bootmeldungen ebenfalls auf das LCD-Display
+legen, so daß der Boot-Vorgang direkt und ohne weitere Hilfsmittel
+analysiert werden kann.
+
+Beispiel:
+
+In U-Boot werden folgende Environment-Variablen gesetzt und abgespei-
+chert:
+
+(1) => setenv magic_keys 01234#X
+(2) => setenv key_cmd# setenv addfb setenv bootargs \\${bootargs} console=tty0 console=ttyS1,\\${baudrate}
+(3) => setenv nfsargs setenv bootargs root=/dev/nfs rw nfsroot=\${serverip}:\${rootpath}
+(4) => setenv addip setenv bootargs \${bootargs} ip=\${ipaddr}:\${serverip}:\${gatewayip}:\${netmask}:\${hostname}::off panic=1
+(5) => setenv addfb setenv bootargs \${bootargs} console=ttyS1,\${baudrate}
+(6) => setenv bootcmd bootp\;run nfsargs\;run addip\;run addfb\;bootm
+
+Hierbei wird die Linux Commandline (in der Variablen "bootargs") im
+Boot-Kommando "bootcmd" (6) schrittweise zusammengesetzt: zunächst
+werden die für Root-Filesystem über NFS erforderlichen Optionen ge-
+setzt ("run nfsargs", vgl. (3)), dann die Netzwerkkonfiguration an-
+gefügt ("run addip", vgl. (4)), und schließlich die Systemconsole
+definiert ("run addfb").
+
+Dabei wird im Normalfall die Definition (5) verwendt; wurde aller-
+dings beim Reset die entsprechende Taste gedrückt gehalten, so wird
+diese Definition bei der Ausführung des in (2) definierten Kommandos
+überschrieben, so daß Linux die Bootmeldungen auch über das Frame-
+buffer-Device (=LCD-Display) ausgibt.
+
+Beachten Sie die Verdoppelung der '\'-Escapes in der Definition von
+"key_cmd#" - diese ist erforderlich, weil der String _zweimal_ inter-
+pretiert wird: das erste Mal bei der Eingabe von "key_cmd#", das
+zweite Mal, wenn der String (als Inhalt von "preboot") ausgeführt
+wird.
