i am comparing http://opencores.org/or1k/OpenRISC_GNU_tool_chain#Installation_of_development_versions
against http://opencores.org/or1k/Ubuntu_VirtualBox-image_updates_and_information and trying to build the kernel. the new toolchain rejects UART_DLL and UART_DLM in arch/openrisc/kernel/head.S with "Error: unresolved expression that must be resolved". i searched the linux sources for where these are defined, many places do, and think linux/serial_reg.h is the most sensible to include. the following patch does quash the error but i submit for folks more knowledgable than i to decide if it is really correct. --- arch/openrisc/kernel/head.S~ 2013-02-20 17:32:11.132491912 -0700 +++ arch/openrisc/kernel/head.S 2013-02-20 17:32:50.824316622 -0700 @@ -26,6 +26,7 @@ #include <asm/cache.h> #include <asm/spr_defs.h> #include <asm/asm-offsets.h> +#include <linux/serial_reg.h> #include <linux/of_fdt.h> #define tophys(rd,rs) \ :{)} _______________________________________________ Linux mailing list [email protected] http://lists.openrisc.net/listinfo/linux
