Jagannadha Sutradharudu Teki11704c22014-01-09 01:48:21 +0530[diff] [blame]35
36Zynq has a facility to read the bootmode from the slcr bootmode register
37once user is setting through jumpers on the board - see page no:1546 on [5]
38
39All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
40on [5].
41
42board_late_init() will read the bootmode values using slcr bootmode register
43at runtime and assign the modeboot variable to specific bootmode string which
44is intern used in autoboot.
45
46SLCR bootmode register Bit[3:0] values
47#define ZYNQ_BM_NOR 0x02
48#define ZYNQ_BM_SD 0x05
49#define ZYNQ_BM_JTAG 0x0
50
51"modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
52bootmode strings at runtime.
