+SPEAr (Structured Processor Enhanced Architecture).
+
+SPEAr600 is also known as SPEArPlus and SPEAr300 is also known as SPEArBasic
+
+The SPEAr SoC family also embeds a customizable logic that could 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.
+Pls note that SPEAr300/310/320 differs only for the default customization.
+
+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 ..
+
+sp600 is not customized by default.
+sp3xx are differently customized...
+sp300 is more oriented to TELECOM/video (it has tdm, i2s, ITU i/f support)
+sp310 for networking (a part GMAC in fixed part, it has 5 MACB ctrls in
+custom)
+sp320 for industrial (SPP ctrl, CAN ctrl, 2 MACBs, ...)
+
+Everything is supported in Linux.
+u-boot is not currently supporting all peripeharls (just a few).
+
+More description can be found on Internet, for example here:
+
+http://embedded-system.net/spear-basic-customizable-arm-based-soc-stmicroelectronics.html
+
+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
