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
