The Virtex support in Linus' tree is a mess. When I ported the common devices over to using the platform bus I tried the use the ppc_sys infrastructure. ppc_sys is intended for SoCs that have a fixed set of devices. It is the *wrong* approach for FPGA support, and I made a royal mess of things. This patch set fixes that problem and makes a number of other changes that make supporting Virtex boards easier.
I do know that changes to arch/ppc are frowned upon at the moment. However, 4xx support in arch/powerpc is not merged yet, and Virtex support needs additional work beyond that. I suspect that arch/ppc support for the 4xx parts is going to need to stay alive for the next 2-3 kernel releases anyway while arch/powerpc support stablizes. Getting these patches in will make it easier to support the Virtex ports while I hack on getting arch/powerpc stuff figured out. arch/ppc/boot/common/misc-common.c | 15 ++- arch/ppc/boot/simple/Makefile | 1 + arch/ppc/boot/simple/uartlite_tty.c | 37 ++++++ arch/ppc/platforms/4xx/Kconfig | 13 +- arch/ppc/platforms/4xx/Makefile | 1 - arch/ppc/platforms/4xx/virtex.c | 56 --------- arch/ppc/platforms/4xx/virtex.h | 47 +++++--- arch/ppc/platforms/4xx/xilinx_ml300.c | 65 +---------- arch/ppc/platforms/4xx/xilinx_ml300.h | 45 ------- arch/ppc/platforms/4xx/xilinx_ml403.c | 66 +---------- arch/ppc/platforms/4xx/xilinx_ml403.h | 49 -------- arch/ppc/syslib/Makefile | 3 +- arch/ppc/syslib/virtex_devices.c | 209 +++++++++++++++++++++++++++++++++ arch/ppc/syslib/virtex_devices.h | 27 +++++ include/asm-ppc/ibm4xx.h | 8 +- include/asm-ppc/ppc_sys.h | 2 - 16 files changed, 335 insertions(+), 309 deletions(-) _______________________________________________ Linuxppc-embedded mailing list [EMAIL PROTECTED] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
