| 2 | SPEAr (Structured Processor Enhanced Architecture). | |
| 3 | ||
| 4 | SPEAr600 is also known as SPEArPlus and SPEAr300 is also known as SPEArBasic | |
| 5 | ||
| 6 | The SPEAr SoC family embeds a customizable logic that can be programmed | |
| 7 | one-time by a customer at silicon mask level (i.e. not at runtime!). | |
| 8 | ||
| 9 | We are now adding the support in u-boot for two SoC: SPEAr600 and SPEAr3xx. | |
| 10 | ||
| 11 | All 4 SoCs share common peripherals. | |
| 12 | ||
| 13 | 1. ARM926ejs core based (sp600 has two cores, the 2nd handled only in Linux) | |
| 14 | 2. FastEthernet (sp600 has Gbit version, but same controller - GMAC) | |
| 15 | 3. USB Host | |
| 16 | 4. USB Device | |
| 17 | 5. NAND controller (FSMC) | |
| 18 | 6. Serial NOR ctrl | |
| 19 | 7. I2C | |
| 20 | 8. SPI | |
| 21 | 9. CLCD | |
| 22 | 10. others .. | |
| 23 | ||
| 24 | Everything is supported in Linux. | |
| 25 | u-boot is not currently supporting all peripeharls (just a few as listed below). | |
| 26 | 1. USB Device | |
| 27 | 2. NAND controller (FSMC) | |
| 28 | 3. Serial Memory Interface | |
| 29 | 4. EMI (Parallel NOR interface) | |
| 30 | 4. I2C | |
| 31 | 5. UART | |
| 32 | ||
| 33 | Build options | |
| 34 | make spear600_config | |
| 35 | make spear300_config | |
| 36 | make spear310_config | |
| 37 | make spear320_config | |
| 38 | ||
| 39 | Further options | |
| 40 | make ENV=NAND (supported by all 4 SoCs) | |
| 41 | - This option generates a uboot image that saves environment inn NAND | |
| 42 | ||
| 43 | make CONSOLE=USB (supported by all 4 SoCs) | |
| 44 | - This option generates a uboot image for using usbdevice as a tty i/f | |
| 45 | ||
| 46 | make FLASH=PNOR (supported by SPEAr310 and SPEAr320) | |
| 47 | - This option generates a uboot image that supports emi controller for | |
| 48 | CFI compliant parallel NOR flash |
