-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!).
-
-U-Boot supports four SoCs: SPEAr600, SPEAr3xx
-
-All 4 SoCs (SPEAr3xx and SPEAr600) share common peripherals. SPEAr300 and
-SPEAr600 do not have EMI.
-
-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 currently not 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 spear320_config
- spear320 build with environment variables placed at default
- location i.e. Serial NOR device
- make spear320_pnor_config
- This option generates a uboot image that supports emi controller
- for CFI compliant parallel NOR flash. Environment variables are
- placed in Parallel NOR device
- make spear320_nand_config

- make spear320_usbtty_config

-Mac id storage and retrieval in spear platforms
-
-Please read doc/README.enetaddr for the implementation guidelines for mac id
-usage. Basically, environment has precedence over board specific storage. The
-ethaddr beeing used for the network interface is always taken only from
-environment variables. Although, we can check the mac id programmed in i2c
-memory by using chip_config command
