| 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 |
