2 SPEAr (Structured Processor Enhanced Architecture).
4 SPEAr600 is also known as SPEArPlus and SPEAr300 is also known as SPEArBasic
6 The SPEAr SoC family embeds a customizable logic that can be programmed
7 one-time by a customer at silicon mask level (i.e. not at runtime!).
9 We are now adding the support in u-boot for two SoC: SPEAr600 and SPEAr3xx.
11 All 4 SoCs share common peripherals.
13 1. ARM926ejs core based (sp600 has two cores, the 2nd handled only in Linux)
14 2. FastEthernet (sp600 has Gbit version, but same controller - GMAC)
17 5. NAND controller (FSMC)
24 Everything is supported in Linux.
25 u-boot is not currently supporting all peripeharls (just a few as listed below).
27 2. NAND controller (FSMC)
28 3. Serial Memory Interface
29 4. EMI (Parallel NOR interface)
40 make ENV=NAND (supported by all 4 SoCs)
41 - This option generates a uboot image that saves environment inn NAND
43 make CONSOLE=USB (supported by all 4 SoCs)
44 - This option generates a uboot image for using usbdevice as a tty i/f
46 make FLASH=PNOR (supported by SPEAr310 and SPEAr320)
47 - This option generates a uboot image that supports emi controller for
48 CFI compliant parallel NOR flash
