| SPEAr (Structured Processor Enhanced Architecture). |
| |
| SPEAr600 is also known as SPEArPlus and SPEAr300 is also known as SPEArBasic |
| |
| The SPEAr SoC family embeds a customizable logic that can be programmed |
| one-time by a customer at silicon mask level (i.e. not at runtime!). |
| |
| We are now adding the support in u-boot for two SoC: SPEAr600 and SPEAr3xx. |
| |
| All 4 SoCs share common peripherals. |
| |
| 1. ARM926ejs core based (sp600 has two cores, the 2nd handled only in Linux) |
| 2. FastEthernet (sp600 has Gbit version, but same controller - GMAC) |
| 3. USB Host |
| 4. USB Device |
| 5. NAND controller (FSMC) |
| 6. Serial NOR ctrl |
| 7. I2C |
| 8. SPI |
| 9. CLCD |
| 10. others .. |
| |
| Everything is supported in Linux. |
| u-boot is not currently supporting all peripeharls (just a few as listed below). |
| 1. USB Device |
| 2. NAND controller (FSMC) |
| 3. Serial Memory Interface |
| 4. EMI (Parallel NOR interface) |
| 4. I2C |
| 5. UART |
| |
| Build options |
| make spear600_config |
| make spear300_config |
| make spear310_config |
| make spear320_config |
| |
| Further options |
| make ENV=NAND (supported by all 4 SoCs) |
| - This option generates a uboot image that saves environment inn NAND |
| |
| make CONSOLE=USB (supported by all 4 SoCs) |
| - This option generates a uboot image for using usbdevice as a tty i/f |
| |
| make FLASH=PNOR (supported by SPEAr310 and SPEAr320) |
| - This option generates a uboot image that supports emi controller for |
| CFI compliant parallel NOR flash |
