| 10 | |
| 11 | This document describes the information about Xilinx Zynq U-Boot - |
| 12 | like supported boards, ML status and TODO list. |
| 13 | |
| 14 | 2. Zynq boards |
| 15 | |
| 16 | Xilinx Zynq-7000 All Programmable SoCs enable extensive system level |
| 17 | differentiation, integration, and flexibility through hardware, software, |
| 18 | and I/O programmability. |

| 43 | 4. Bootmode |
| Jagannadha Sutradharudu Teki | 11704c2 | 2014-01-09 01:48:21 +0530 | [diff] [blame] | 44 | |
| 45 | Zynq has a facility to read the bootmode from the slcr bootmode register |
| 46 | once user is setting through jumpers on the board - see page no:1546 on [5] |
| 47 | |
| 48 | All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins |
| 49 | on [5]. |
| 50 | |
| 51 | board_late_init() will read the bootmode values using slcr bootmode register |
| 52 | at runtime and assign the modeboot variable to specific bootmode string which |
| 53 | is intern used in autoboot. |
| 54 | |
| 55 | SLCR bootmode register Bit[3:0] values |
| 56 | #define ZYNQ_BM_NOR 0x02 |
| 57 | #define ZYNQ_BM_SD 0x05 |
| 58 | #define ZYNQ_BM_JTAG 0x0 |
| 59 | |
| 60 | "modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot" |
| 61 | bootmode strings at runtime. |
