Wolfgang,
Please pull sparc. u-boot-sparc.git master.
I have added support for LEON2 and LEON3 SPARC processors and their simmulators. I have summarized some SPARC/LEON info below, I hope you find it usefull. Tried to make a short comment for all the patches, I think most of them are pretty obvious anyway.
git://www.denx.de/git/u-boot-sparc.git sparc is my testing branch.
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) - LEON2 Simmulator (GRSIM and TSIM) - Network (GRETH and SMC91111 and USB) - 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
