From 3d597c04ed42d61fcd22a42f1d68c4b1621334fe Mon Sep 17 00:00:00 2001 From: Hesham ALMatary Date: Sat, 18 Apr 2015 17:25:51 +0100 Subject: Rename or1ksim BSP to generic_or1k or1ksim BSP was initially named after or1ksim simulator, and it was intented to only run there. But now it can also run on QEMU, jor1k and real FPGA boards without modifications. It makes more sense to give it a new generic name like generic_or1k. --- c/src/lib/libbsp/or1k/acinclude.m4 | 4 +- c/src/lib/libbsp/or1k/configure.ac | 2 +- c/src/lib/libbsp/or1k/generic_or1k/Makefile.am | 110 +++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/README | 34 ++++ c/src/lib/libbsp/or1k/generic_or1k/bsp_specs | 11 ++ .../lib/libbsp/or1k/generic_or1k/clock/clockdrv.c | 152 +++++++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/configure.ac | 30 ++++ .../or1k/generic_or1k/console/console-config.c | 58 +++++++ c/src/lib/libbsp/or1k/generic_or1k/console/uart.c | 152 +++++++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/include/bsp.h | 47 ++++++ .../or1k/generic_or1k/include/generic_or1k.h | 118 +++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/include/irq.h | 45 +++++ c/src/lib/libbsp/or1k/generic_or1k/include/uart.h | 42 +++++ c/src/lib/libbsp/or1k/generic_or1k/irq/irq.c | 42 +++++ .../make/custom/generic_or1k-testsuite.tcfg | 5 + .../or1k/generic_or1k/make/custom/generic_or1k.cfg | 7 + c/src/lib/libbsp/or1k/generic_or1k/preinstall.am | 120 ++++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/sim.cfg | 105 ++++++++++++ c/src/lib/libbsp/or1k/generic_or1k/start/start.S | 182 +++++++++++++++++++++ .../libbsp/or1k/generic_or1k/startup/bspstart.c | 25 +++ .../lib/libbsp/or1k/generic_or1k/startup/linkcmds | 41 +++++ c/src/lib/libbsp/or1k/generic_or1k/timer/timer.c | 64 ++++++++ c/src/lib/libbsp/or1k/or1ksim/Makefile.am | 110 ------------- c/src/lib/libbsp/or1k/or1ksim/README | 37 ----- c/src/lib/libbsp/or1k/or1ksim/bsp_specs | 11 -- c/src/lib/libbsp/or1k/or1ksim/clock/clockdrv.c | 149 ----------------- c/src/lib/libbsp/or1k/or1ksim/configure.ac | 30 ---- .../libbsp/or1k/or1ksim/console/console-config.c | 58 ------- c/src/lib/libbsp/or1k/or1ksim/console/uart.c | 152 ----------------- c/src/lib/libbsp/or1k/or1ksim/include/bsp.h | 47 ------ c/src/lib/libbsp/or1k/or1ksim/include/irq.h | 45 ----- c/src/lib/libbsp/or1k/or1ksim/include/or1ksim.h | 118 ------------- c/src/lib/libbsp/or1k/or1ksim/include/uart.h | 42 ----- c/src/lib/libbsp/or1k/or1ksim/irq/irq.c | 42 ----- .../or1ksim/make/custom/or1ksim-testsuite.tcfg | 5 -
