arc: remove dummy target

2015-05-13T16:20:35Z

TARGET_DUMMY was introduced to resolve the same problem as commit "arch: Make board selection choices optional" http://git.denx.de/?p=u-boot.git;a=commit;h=a26cd04920dc069fd6e91abb785426cf6c29f45f Latter implementation is much cleaner and appropriate. And anyways TARGET_DUMMY is no longer required. Signed-off-by: Alexey Brodkin Acked-by: Joe Hershberger

arc: use more universal prefix for default CROSS_COMPILE

2015-05-13T10:44:25Z

As doc/README.ARC says, pre-build ARC toolchains are available at the Synopsys GitHub page. The bin files are prefixed with arc(eb)-buildroot-linux- for earlier releases, but with arc(eb)-snps-linux- for the latest releases. The symbolic links prefixed with arc(eb)-linux- are also available for all the release, so those prefixes can be used as the default CROSS_COMPILE regardless of the toolchains version/variants.

arch: Make board selection choices optional

2015-05-12T22:10:02Z

By making the board selections optional, every defconfig will include the board selection when running savedefconfig so if a new board is added to the top of the list of choices the former top's defconfig will still be correct.

arc: fix separate compilation of start.o

2015-04-10T16:22:40Z

While testing "arc: make sure _start is in the beginning of .text section" I haven't done proper clean-up of built binaries and so missed another tiny bit that lead to the following error: --->8--- LD u-boot arc-linux-ld.bfd: cannot find arch/arc/lib/start.o Makefile:1107: recipe for target 'u-boot' failed make: *** [u-boot] Error 1 --->8--- Fix is trivial: put "start.o" in "extra-y".

arc: make sure _start is in the beginning of .text section

2015-04-10T15:45:34Z

This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is. In its turn if it deals with binary image of U-Boot there's no way for pre-bootloader to get required value. Signed-off-by: Alexey Brodkin

arc: add support for SLC (System Level Cache, AKA L2-cache)

2015-04-03T06:47:50Z

ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache). This change adds functions required for controlling SLC: * slc_enable/disable * slc_flush/invalidate For now we just disable SLC to escape DMA coherency issues until either: * SLC flush/invalidate is supported in DMA APIin U-Boot * hardware DMA coherency is implemented (that might be board specific so probably we'll need to have a separate Kconfig option for controlling SLC explicitly) Signed-off-by: Alexey Brodkin

serial-arc: switch to DM

2015-04-03T06:47:49Z

Now when all infrastructure in ARC is ready for it let's switch ARC UART to driver model. Signed-off-by: Alexey Brodkin Cc: Masahiro Yamada Cc: Simon Glass

arc: minor fixes in Kconfig

2015-04-03T06:47:49Z

[1] Fix misspeling in ARC_CACHE_LINE_SHIFT dependency, now cache-line lenth selection is correctly enabled if either I$ or D$ are enabled. [2] Add dummy entry to target list to make sure target type is always mentioned in defconfig. Otherwise defconfig for the first target in the list will not have target name and later on with addition of the new target on top of the list in Kconfig will lead to corrupted configuration expanded from defconfig.
