Tue, 21 Mar 2017 11:49:49 +0000

arc: use timer driver for ARC boardsThis commit replaces legacy timer code with usage of arc timerdriver.It removes arch/arc/lib/time.c file and selects CONFIG_CLK,CONFIG_TIMER and CONFIG_ARC_TIMER options for all ARC boards by default.Therefore we remove CONFIG_CLK option from less common axs101 andaxs103 defconfigs.Also it removes legacy CONFIG_SYS_TIMER_RATE config symbol fromaxs10x.h, tb100.h and nsim.h configs files as it is no longer required.Signed-off-by: Vlad Zakharov Reviewed-by: Simon Glass List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

Merge git://git.denx.de/u-boot-arcThis replaces legacy arch/arc/lib/timer.c implementation and allows usto describe ARC Timers in Device Tree. Among other things that way wemay properly inherit Timer's clock from CPU's clock s they really runsynchronously. List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

Fri, 10 Apr 2015 15:41:58 +0000

arc: make sure _start is in the beginning of .text sectionThis is important to have entry point in the beginning of .text sectionbecause it allows simple loading and execution of U-Boot.For example pre-bootloader loads U-Boot in memory starting from offset0x81000000 and then just jumps to the same address.Otherwise pre-bootloader would need to find-out where entry-point is. Inits turn if it deals with binary image of U-Boot there's no way forpre-bootloader to get required value.Signed-off-by: Alexey Brodkin List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

Tue, 24 Feb 2015 16:40:36 +0000

arc: clean-up init procedureIntention behind this work was elimination of as much assembly-writtencode as it is possible.In case of ARC we already have relocation fix-up implemented in C so whydon't we use C for U-Boot copying, .bss zeroing etc.It turned out x86 uses pretty similar approach so we re-used parts ofcode in "board_f.c" initially implemented for x86.Now assembly usage during init is limited to stack- and frame-pointersetup before and after relocation.Signed-off-by: Alexey Brodkin Cc: Simon Glass List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

arc: move low-level interrupt and exception handlers in a separate fileThis separation makes maintenance of code easier because those low-levelinterrupt- or exception handling routines are pretty static and usuallyrequire not much care while start-up code is a subject of modificationsand enhancements.Signed-off-by: Alexey Brodkin List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

arc: merge common start-up code between ARC and ARCv2Even though ARCompact and ARCv2 are not binary compatible most ofassembly instructions are used in both. With this change we'll get ridof duplicate code.Still IVTs are implemented differently so we're keeping them in separatefiles.Signed-off-by: Alexey Brodkin List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

arc: build libgcc in U-BootThis way we may have very limited set of functions implemented so wesave some space.Also it allows us to build U-Boot for any ARC core with the same onetoolchain because we don't rely on pre-built libgcc.For example: * we may use little-endian toolchain but build U-Boot for etherendianess * we may use non-multilibbed uClibc toolchain but build U-Boot forwhatever ARC CPU flavour that current GCC supportsPrivate libgcc built from generic C implementation contributes only 144bytes to .text section so we don't see significant degradation of size:--->8---$ arc-linux-size u-boot.libgcc-prebuilt text data bss dec hex filename 222217 24912 214820 461949 70c7d u-boot.libgcc-prebuilt$ arc-linux-size u-boot.libgcc-private text data bss dec hex filename 222361 24912 214820 462093 70d0d u-boot.libgcc-private--->8---Also I don't notice visible performance degradation compared topre-built libgcc (where at least "*div*" functions are had-written inassembly) on typical operations of downloading 10Mb uImage over TFTP andbootm.Signed-off-by: Alexey Brodkin List of files: /rk3399_rockchip-uboot/arch/arc/lib/Makefile

Sat, 27 Dec 2014 23:42:12 +0000

arc: move common sources in library"reset.c" and "cpu.c" have no architecture-specific code at all.Others are applicable to either ARC CPU.This change is a preparation to submission of ARCv2 architecture port.Even though ARCv1 and ARCv2 ISAs are not binary compatible most ofbuilt-in modules still have the same programming model - AUX registersare mapped in the same addresses and hold the same data (new featuesextend existing ones).So only low-level assembly code (start-up, interrupt handlers) is leftas CPU(actually ISA)-specific.
