* nds32: fix unused pmu_init warningMike Frysinger2012-08-11-0/+2
| | | | | | | | | | | Fixes the build-time warning: board.c: At top level: board.c:106: warning: 'pmu_init' defined but not used This makes the ifdef logic at the call site match the logic at the function definition. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* nds32: delete unused local variableMike Frysinger2012-08-11-1/+0
| | | | | | | | Fixes the build-time warning: board.c: In function 'board_init_r': board.c:304: warning: unused variable 's' Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* nds32: drop bi_enetaddr from global dataMike Frysinger2012-08-11-1/+0
| | | | | | | Nothing is using this, so punt it from the gd. Seems to just be a copy & paste wart from the initial port. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* global_data: unify global flag definesMike Frysinger2012-08-09-13/+1
| | | | | | | All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* nds32: split common cache access from cpu into libMacpaul Lin2012-07-20-225/+158
| | | | | | | | | | | This commit does the following updates. 1. Split the common cache access from cpu.c into lib folder. 2. Rename the following cache api to adapt common.h - dcache_flush_rang -> flush_dcache_rang - icache_inval_range -> invalidate_icache_range 3. Add invalidate_dcache_range Signed-off-by: Macpaul Lin <macpaul@gmail.com>
* net: move bootfile init into eth_initializeMike Frysinger2012-05-15-6/+0
| | | | | | | | All arches init this the same way, so move the logic into the core net code to avoid duplicating it everywhere else. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
* net: punt bd->bi_ip_addrMike Frysinger2012-05-15-4/+0
| | | | | | | | | This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var.
