An undocumented register? Are the specifications not released for the series <= r700? But I have to confess to never read the specifications of ATI/AMD.
Have you found something? Are you able to try to build pcm030_config with a recent checkout? ============= make -C drivers/rtc/ make[1]: Entering directory `/home/maggu2810/phytec/u-boot/u-boot.git_20090401/drivers/rtc' make[1]: Leaving directory `/home/maggu2810/phytec/u-boot/u-boot.git_20090401/drivers/rtc' make[1]: Entering directory `/home/maggu2810/phytec/u-boot/u-boot.git_20090401/drivers/rtc' powerpc-603e-linux-gnu-gcc -g -Os -fPIC -ffixed-r14 -meabi -D__KERNEL__ -DTEXT_BASE=0xFFF00000 -I/home/maggu2810/phytec/u-boot/u-boot.git_20090401/include -fno-builtin -ffreestanding -nostdinc -isystem /home/maggu2810/phytec/OSELAS.Toolchain-1.99.3/powerpc-603e-linux-gnu/gcc-4.3.2-glibc-2.8-binutils-2.18-kernel-2.6.27-sanitized/lib/gcc/powerpc-603e-linux-gnu/4.3.2/include -pipe -DCONFIG_PPC -D__powerpc__ -DCONFIG_MPC5xxx -ffixed-r2 -mstring -mcpu=603e -mmultiple -DTEXT_BASE=0xFFF00000 -I/home/maggu2810/phytec/u-boot/u-boot.git_20090401/board -Wall -Wstrict-prototypes -fno-stack-protector -c -o date.o date.c powerpc-603e-linux-gnu-gcc -g -Os -fPIC -ffixed-r14 -meabi -D__KERNEL__ -DTEXT_BASE=0xFFF00000 -I/home/maggu2810/phytec/u-boot/u-boot.git_20090401/include -fno-builtin -ffreestanding -nostdinc -isystem /home/maggu2810/phytec/OSELAS.Toolchain-1.99.3/powerpc-603e-linux-gnu/gcc-4.3.2-glibc-2.8-binutils-2.18-kernel-2.6.27-sanitized/lib/gcc/powerpc-603e-linux-gnu/4.3.2/include -pipe -DCONFIG_PPC -D__powerpc__ -DCONFIG_MPC5xxx -ffixed-r2 -mstring -mcpu=603e -mmultiple -DTEXT_BASE=0xFFF00000 -I/home/maggu2810/phytec/u-boot/u-boot.git_20090401/board -Wall -Wstrict-prototypes -fno-stack-protector -c -o pcf8563.o pcf8563.c pcf8563.c:37: error: static declaration of 'rtc_read' follows non-static declaration /home/maggu2810/phytec/u-boot/u-boot.git_20090401/include/rtc.h:64: error: previous declaration of 'rtc_read' was here pcf8563.c:38: error: static declaration of 'rtc_write' follows non-static declaration /home/maggu2810/phytec/u-boot/u-boot.git_20090401/include/rtc.h:65: error: previous declaration of 'rtc_write' was here make[1]: *** [pcf8563.o] Error 1 make[1]: Leaving directory `/home/maggu2810/phytec/u-boot/u-boot.git_20090401/drivers/rtc' make: *** [drivers/rtc/librtc.a] Error 2 ============= On Mon, Mar 30, 2009 at 7:09 PM, Jon Smirl <jonsm...@gmail.com> wrote: > On Mon, Mar 30, 2009 at 12:13 PM, Anatolij Gustschin <ag...@denx.de> wrote: >> Jon Smirl wrote: >>> On Sun, Mar 29, 2009 at 10:08 AM, Markus Rathgeb >>> <maggu2...@googlemail.com> wrote: >>>> Hi! >>>> >>>> Have you read the BIOSEMU stuff in the mailing list? >>>> Can you adjust the PCI section and perhaps you can include the video >>>> example (set undef video). >>> >>> I have v1 of the pcm030 hardware and the baseboard doesn't have a PCI slot. >>> >>> I looked at some of your older emails.
