2018-05-31Merge tag 'arc-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arcTom Rini
Here we do a couple of minor fixes like: - Move .ivt section to the very beginning of the image by default which allows us to use that image put right at reset vector (usually 0x0) - Improve relocation fix-up which became required once we moved .ivt and understood a problem with existing implementation where we relied on a particular placement of sections. Now we don't care about placement because we just explicitly check for .text and in case of ARCompact .ivt sections - Re-implemnt do_reset() such that it calls reset_cpu() which could implmented for a particular board And hte most important part we introduce support for yet another devboard from Synopsys - EMDK.
2018-05-31ARC: Add support for EM Development Kit boardAlexey Brodkin
Synopsys DesignWare ARC EM Development Kit (ARC EMDK) is an FPGA-based development platform from Synopsys aimed to speed-up development of software for ARC EM cores and entire subsystems based on ARC EM like Data Fusion, Secure and Sensor & Control subsystems. U-Boot is supposed to be used as a primary bootloader on EMDK allowing users to easily load and start their application from micro-SD card. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Use elf32-bigarc in case of -EBAlexey Brodkin
As it is stated in LD manual [1] the second entry in OUTPUT_FORMAT corresponds to "-EB" command-line option which for us is "elf32-bigarc". [1] https://sourceware.org/binutils/docs/ld/Format-Commands.html#Format-Commands Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Reset: Implement weak reset_cpu()Alexey Brodkin
This will allow for board-specific implementation of reset. Default version will just stop execution with help of BRK instruction. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Reset: Use __builtin_arc_brk() instead of open-coded ASMAlexey Brodkin
For quite some time we have a GCC's built-in which inserts BRK instruction so let's use it instead of simple insertion of in-line assembly. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Move .ivt section to the very beginning of the imageAlexey Brodkin
This is useful for cases when U-Boot image is put in ROM and reset vector points to 0 where the very beginnign of the image reside. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Improve relocation fix-upsAlexey Brodkin
We used to have the one and only linker script for all ARC boards and so we relied on a particular order of symbols there. Because of that we used __ivt_end as the marker of the end of all the code which won't be true any longer if we move .ivt section to any other place. That said we'd better check for each section separately. A couple of other improvements: 1. There's no point to include the marker of section end in interested range because its address is beyond the section, i.e. we should compare with "<" but not "<=". 2. .ivt section for ARCv2 cores is just an array of 32-bit ints and they are not swapped even on little-endia cores while in case of ARCompact cores .ivt contains valid code so swapping is required. 3. Just in case add check for ARC600 which is also ARCompact and its .ivt is normal code. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-31ARC: Make sure .ivt section is not purged by garbage collectorAlexey Brodkin
Fixes commit fac4790491f6 ("arc: Eliminate unused code and data with GCC's garbage collector"), see [1]. Since in case of ARCv2 .ivt only contains addrresses of interrupt/exception handlers linker doesn't understand that this section actually make a lot of sense and decides to get rid of it if we use "--gc-sections". And KEEP does exactly this, see [2].

2018-05-31ARC: Cache: Don't compare I$ and D$ line lengthsAlexey Brodkin
We don't care much about I$ line length really as there're no per-line ops on I$ instead we only do full invalidation of it on occasion of relocation and right before jumping to the OS. Also as compared to Linux kernel where we don't support different lengths of I$ and D$ lines in U-Boot we have to deal with such an exotic configs if the target board is not supposed to run Linux kernel.

2018-05-31test: dm: Fix wrong aliases property namesEugeniu Rosca
After importing v4.17-rc1 Linux commit 9130ba884640 ("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987"), sandbox build reports below warnings: arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' Silent them by applying the 's/_/-/' substitution in the names of the 'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties. Similar DTC warnings have been recently fixed in Linux kernel, e.g. via v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name for STi boards"). If done alone, the DTS update generates a failure of the `ut dm fdt_translation` unit test in sandbox environment as seen below: $ ./u-boot -d arch/sandbox/dts/test.dtb ---<-snip->--- => ut dm fdt_translation Test: dm_test_fdt_translation: test-fdt.c test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19 Test: dm_test_fdt_translation: test-fdt.c (flat tree) test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19 Failures: 2 ---<-snip->--- Fix this issue in place, by updating the "name" string in the UCLASS_DRIVER(fdt_dummy) definition, so that it matches the newly updated aliases properties.
