- 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
