2022-04-18ARC: dts: align SPI NOR node name with dtschemaKrzysztof Kozlowski1-1/+1
The node names should be generic and SPI NOR dtschema expects "flash". Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Vineet Gupta <vgupta@kernel.org>
2022-01-08kbuild: do not quote string values in include/config/auto.confMasahiro Yamada1-2/+2
The previous commit fixed up all shell scripts to not include include/config/auto.conf. Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf. These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAME I checked them one by one, and fixed up the code where necessary.

2020-12-01ARC: build: move symlink creation to arch/arc/Makefile to avoid raceMasahiro Yamada1-10/+1
If you run 'make uImage uImage.gz' with the parallel option, uImage.gz will be created by two threads simultaneously. This is because arch/arc/Makefile does not specify the dependency between uImage and uImage.gz. Hence, GNU Make assumes they can be built in parallel. One thread descends into arch/arc/boot/ to create uImage, and another to create uImage.gz. Please notice the same log is displayed twice in the following steps: $ export CROSS_COMPILE=<your-arc-compiler-prefix> $ make -s ARCH=arc defconfig $ make -j$(nproc) ARCH=arc uImage uImage.gz [ snip ] LD vmlinux SORTTAB vmlinux SYSMAP System.map OBJCOPY arch/arc/boot/vmlinux.bin OBJCOPY arch/arc/boot/vmlinux.bin GZIP arch/arc/boot/vmlinux.bin.gz GZIP arch/arc/boot/vmlinux.bin.gz UIMAGE arch/arc/boot/uImage.gz UIMAGE arch/arc/boot/uImage.gz Image Name: Linux-5.10.0-rc4-00003-g62f23044 Created: Sun Nov 22 02:52:26 2020 Image Type: ARC Linux Kernel Image (gzip compressed) Data Size: 2109376 Bytes = 2059.94 KiB = 2.01 MiB Load Address: 80000000 Entry Point: 80004000 Image arch/arc/boot/uImage is ready Image Name: Linux-5.10.0-rc4-00003-g62f23044 Created: Sun Nov 22 02:52:26 2020 Image Type: ARC Linux Kernel Image (gzip compressed) Data Size: 2815455 Bytes = 2749.47 KiB = 2.69 MiB Load Address: 80000000 Entry Point: 80004000 This is a race between the two threads trying to write to the same file arch/arc/boot/uImage.gz. This is a potential problem that can generate a broken file. I fixed a similar problem for ARM by commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images"). I highly recommend to avoid such build rules that cause a race condition. Move the uImage rule to arch/arc/Makefile. Another strangeness is that arch/arc/boot/Makefile compares the timestamps between $(obj)/uImage and $(obj)/uImage.*: $(obj)/uImage: $(obj)/uImage.$(suffix-y) @ln -sf $(notdir $<) $@ @echo ' Image $@ is ready' This does not work as expected since $(obj)/uImage is a symlink. The symlink should be created in a phony target rule. I used $(kecho) instead of echo to suppress the message 'Image arch/arc/boot/uImage is ready' when the -s option is given.

2020-09-01ARC: [plat-hsdk]: Switch ethernet phy-mode to rgmii-idEvgeniy Didin1-2/+2
HSDK board has Micrel KSZ9031, recent commit bcf3440c6dd ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") caused a breakdown of Ethernet. Using 'phy-mode = "rgmii"' is not correct because accodring RGMII specification it is necessary to have delay on RX (PHY to MAX) which is not generated in case of "rgmii". Using "rgmii-id" adds necessary delay and solves the issue. Also adding name of PHY placed on HSDK board.

2019-10-28ARC: merge HAPS-HS with nSIM-HS configsEugeniy Paltsev2-132/+0
Starting from nSIM 2019.06 is possible to use DW UART instead of ARC UART. That allows us to merge "nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp" with minor changes which were done in previous commits. We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig and leave haps_hs_defconfig and haps_hs_smp_defconfig which can be used on HAPS / nSIM / ZEBU / QEMU platforms without additional changes in Linux kernel. For nSIM we should now use UART property values "-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000" instead of previously used "-prop=nsim_mem-dev=uart0,base=0xc0fc1000" "use_connect" and "irq" values of UART property remains untouched.

2019-08-05ARC: [plat-hsdk]: allow to switch between AXI DMAC port configurationsEugeniy Paltsev1-0/+3
We want to use DW AXI DMAC on HSDK board in our automated verification to test cache & dma kernel code changes. This is perfect candidate as we don't depend on any external peripherals like MMC card / USB storage / etc. To increase test coverage we want to test both options: * DW AXI DMAC is connected through IOC port & dma direct ops used * DW AXI DMAC is connected to DDR port & dma noncoherent ops used Introduce 'arc_hsdk_axi_dmac_coherent' global variable which can be modified by debugger (same way as we patch 'ioc_enable') to switch between these options without recompiling the kernel. Depend on this value we tweak memory bridge configuration and "dma-coherent" DTS property of DW AXI DMAC.

2019-07-08ARC: [haps] Add Virtio supportAlexey Brodkin1-0/+30
As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO peripherals support for the platform we're going to use. For now we add 5 Virtio slots in .dts and enable block and network devices via Virtio-MMIO. Note even though typically Virtio register set fits in 0x200 bytes we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size and so remapping of that area is done clearly. We also enable DEVTMPFS automount for more convenient use of external root file-stystem. Before that we used to use built-in Initramfs which didn't automount DEVTMPFS anyways so we didn't need that option, while now it starts making sense.

2018-08-27ARC: [plat-axs*/plat-hsdk]: Allow U-Boot to pass MAC-address to the kernelAlexey Brodkin2-2/+12
Otherwise kernel uses random MAC which is not very conveniet. With that change in place use might set desired MAC in U-Boot with "setenv ethaddr 11:22:33:44:55:66", save environment and then from boot to boot the same MAC will be used by the kernel. One other note for this to happen it's required to pass board's .dtb in U-Boot's "bootm" command like that: ------------------->8----------------- bootm 0x82000000 - 0x84000000 ------------------->8----------------- Here 0x82000000 is location of uImage while 0x80000000 is location of either axs10x.dtb or hsdk.dtb previously loaded from SD-card, USB storage or TFTP server.

2018-04-07kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markersMasahiro Yamada1-2/+0
GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped A couple of makefiles mark such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. Another difference is that .PRECIOUS works with pattern rules whereas .SECONDARY does not. .PRECIOUS: $(obj)/%.lex.c works, but .SECONDARY: $(obj)/%.lex.c has no effect. However, for the reason above, I do not want to use .PRECIOUS which could cause obscure build breakage. The targets specified as .SECONDARY must be explicit. $(targets) contains all targets that need to include .*.cmd files. So, the intermediates you want to keep are mostly in there. Therefore, mark $(targets) as .SECONDARY. It means primary targets are also marked as .SECONDARY, but I do not see any drawback for this. I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This will make Kbuild search for non-existing .*.cmd files, but this is not a noticeable performance issue.

2018-01-18ARC: Enable fatal signals on boot for dev platformsAlexey Brodkin8-8/+8
It's very convenient to have fatal signals enabled on developemnt platform as this allows to catch problems that happen early in user-space (like crashing init or dynamic loader). Otherwise we may either enable it later from alive taregt console by "echo 1 > /proc/sys/kernel/print-fatal-signals" but: 1. We might be unfortunate enough to not reach working console 2. Forget to enable fatal signals and miss something interesting Given we're talking about development platforms here it shouldn't be a problem if a bit more data gets printed to debug console. Moreover this makes behavior of all our dev platforms predictable as today some platforms already have it enabled and some don't - which is way too inconvenient.
