SPARC: Added generic support for SPARC architecture.

Not much to say, tested on LEON2 simulator and LEON3.

ABOUT SPARC-ELF COMPILER
------------------------
Compiling u-boot for LEON3 and LEON2 has only been has been tested with GCC 3.4.4 compiler with added LEON2 and LEON3 support available from www.gaisler.com or ftp://ftp.gaisler.com/gaisler.com/bcc/bin/linux/sparc-elf-3.4.4-1.0.30.tar.bz2, installation instructions can be found in bcc/doc/bcc.pdf. (extract to /opt/ and add /opt/sparc-elf-3.4.4/bin to PATH).

U-BOOT support tested
---------------------
- LEON3 (and LEON3FT Fault tolerant version)
- LEON3 Simulator (GRSIM and TSIM)
- LEON2 Simulator (GRSIM and TSIM)
- Network (GRETH and SMC91111)
- USB 1.1 (UHCI)
- Linux and RTEMS booting
- booting UBOOT from RAM and FLASH by changing board/gaisler/xxx/config.mk
- DDR, DDR2, SRAM, FT-SRAM
- UART, IRQ, Timer

Hello Wolfgang,

This patch adds support for SPARC u-boot images to bootm. The IH_ARCH_SPARC indentifier in the image header is recognized. The IH_ARCH_SPARC indentifier has already been implemented in mkimage.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Daniel Hellstrom

1.5.4

Hello Wolfgang,

This patch adds support for SPARC/LEON3 to U-Boot. LEON3 boards are added in separate patches.

This patch does not support LEON3 SMP system.

Linux for SPARC assumes that there is a Sun Boot prom available. The boot prom is used as monitor to support basic features such as rebooting, printing to the system console (serial terminal in the LEON case) and getting information about the hardware (baudrate, main memory etc.). So, in order to boot SPARC Linux on LEON a standard boot prom is emulated. This is done in cpu/leon?/prom.c.
The boot prom must be placed at a higher address that the stack to avoid that it gets overwritten.

Some chip designs has UHCI and EHI USB. UHCI has been implemented for U-Boot on LEON3 systems.

LEON3 processors is on an extended AMBA bus (with Plug&Play support), whereas LEON2 uses hardcoded addresses since it is on an AMBA bus without Plug&Play.

ABOUT LEON3 and GRLIB
---------------------
LEON3 is an open source (GPL) SPARC V7 and/or V8 processor part of GRLIB. GRLIB is a free comprehensive open source (GPL) Portable IP library (written in VHDL) featuring cores such as Ethernet 10/100/1000, SpaceWire, PCI, CAN, 1553, I2C, USB 1.1 and 2.0, SPI, DMA ATA, SVGA, PS/2, UART, Timer, SDRAM, SRAM, SSRAM, DDR, DDR2, FLASH/PROM, CPU Debug Unit, FPU, GPIO and many more. More info available at www.gaisler.com.

ABOUT SPARC-ELF COMPILER
------------------------
Compiling u-boot for LEON3 and LEON2 has only been has only been tested with GCC
3.4.4 compiler with added LEON2 and LEON3 support available from www.gaisler.com or ftp://ftp.gaisler.com/gaisler.com/bcc/bin/linux/sparc-elf-3.4.4-1.0.30.tar.bz2,

installation instructions can be found in bcc/doc/bcc.pdf. (extract to /opt/ and
add /opt/sparc-elf-3.4.4/bin to PATH).

U-BOOT support tested
---------------------
- LEON3 (and LEON3FT Fault tolerant version)
- LEON3 Simmulator (GRSIM and TSIM)
- Network (GRETH and SMC91111)
- USB 1.1 (UHCI)
- Linux and RTEMS booting
- booting UBOOT from RAM and FLASH by changing board/gaisler/xxx/config.mk
- DDR, DDR2, SRAM, FT-SRAM
- UART, IRQ, Timer

Hello Wolfgang,

This patch adds an U-Boot command, ambapp, which prints a summary of AMBA Bus Plug & Play information.

AMBA is a bus specified by ARM. AMBA with Plug and Play information is a Gaisler extension to that bus. See www.gaisler.com.

Hello Wolfgang,

This patch adds support for SPARC/LEON2 to U-Boot. Currently only the LEON2 TSIM and GRSIM simulators are supported, they are added in a separate patch.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Hello Wolfgang,

GRETH is an Ethernet 10/100 or 10/100/1000 MAC with out without a debug link (EDCL). The GRETH core is documented in GRIP.pdf available at www.gaisler.com.

If the GRETH has GigaBit support (GBIT, Scatter gather, checksum offloading etc.) can be determined by a bit in the control register. The GBIT MAC is supported by operating in GRTEH 10/100 legacy mode.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Best Regards,
Daniel Hellstrom

Hello Wolfgang,

This patch makes SPARC/LEON processors able to read and write to the SMC91111 chip using the chip external I/O bus of the memory controller. This patchs defines the standard in and out macros expected by the SMC9111 driver.

To access that I/O bus one must set up the memory controller (MCTRL or FTMCTRL) correctly. It is assumed that the user sets up this correctly when the other MCTRL parameters are set up. It can be set up from the board configuration header file.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Best Regards,
Daniel Hellstrom

Oh, I see. Thanks for taking the time Alessandro. I'm putting this back on list so others can be educated too.

Hello Wolfgang,

This patch adds support for the LEON3 board:
* GR-XC3S-1500 (Low cost Xilinx Spartan FPGA board)

Note that by board support I mean support for the pre synthezied template design for the board. Supporting any configuration is not possible but almost, due to the Plug & Play system...
The FPGA can be programmed with the template design by:

 $ cd grlib/designs/BOARD
 $ make ise-prog-prom-ref

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Best Regards,
Daniel Hellstrom

Hello Wolfgang,

This patch adds support for the LEON3 simulators TSIM and GRSIM.

The simulators GRSIM and TSIM for LEON3 has been added as a board. A separate board is needed due to that the FLASH CFI interface has not been implemented in the simulators. Configuring the GR-XC3S-1500 board without FLASH support should run in the simulator.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Best Regards,
Daniel Hellstrom

Hello Wolfgang,

This patch adds support for the LEON2 simulators TSIM and GRSIM.

The simulators GRSIM and TSIM for LEON3 has been added as a board. A separate board is needed due to that the FLASH CFI interface has not been implemented in the simulators.

This patch is also available at ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.

Best Regards,
Daniel Hellstrom
