24

25

+Description:
86
+		It is a read/write file. This attribute exists only if the
87
+		system has booted from the alternate flash chip due to
88
+		expiration of a watchdog timer of AST2400/AST2500 when
89
+		alternate boot function was enabled with 'aspeed,alt-boot'
90
+		devicetree option for that watchdog or with an appropriate
91
+		h/w strapping (for WDT2 only).
92
+
93
+		At alternate flash the 'access_cs0' sysfs node provides:
94
+
95
+			ast2400:
96
+				a way to get access to the primary SPI flash
97
+				chip at CS0 after booting from the alternate
98
+				chip at CS1.
99
+			ast2500:
100
+				a way to restore the normal address mapping
101
+				from (CS0->CS1, CS1->CS0) to (CS0->CS0,
102
+				CS1->CS1).
103
+
104
+		Clearing the boot code selection and timeout counter also
105
+		resets to the initial state the chip select line mapping. When
106
+		the SoC is in normal mapping state (i.e. booted from CS0),
107
+		clearing those bits does nothing for both versions of the SoC.
108
+		For alternate boot mode (booted from CS1 due to wdt2
109
+		expiration) the behavior differs as described above.
110
+
111
+		This option can be used with wdt2 (watchdog1) only.
112
+
113
+		When read, the current status of the boot code selection is
114
+		shown. When written with any non-zero value, it clears
115
+		the boot code selection and the timeout counter, which results
116
+		in chipselect reset for AST2400/AST2500.
