[U-Boot] [PATCH v2 00/15] riscv: Add QEMU virt board support
by Bin Meng 11 Sep '18

11 Sep '18

This series adds QEMU RISC-V 'virt' board target support, with the hope of helping people easily test U-Boot on RISC-V. Some existing RISC-V codes have been changed to make it easily to support new targets. Some spotted coding style issues are fixed. This series is available at u-boot-x86/riscv-working for testing. Changes in v2: - Change Linux kernel entry parameters' type to support 32/64 bit - new patch to remove CSR read/write defines in encoding.h - new patch to pass mhartid CSR value to kernel - new patch to move do_reset() to a common place Bin Meng (15): riscv: kconfig: Normalize architecture name spelling riscv: Remove setup.h riscv: bootm: Correct the 1st kernel argument to hart id riscv: Remove mach type riscv: Move the linker script to the CPU root directory riscv: Fix coding style issues in the linker script riscv: Explicitly pass -march and -mabi to the compiler riscv: Add a helper routine to print CPU information riscv: Remove CSR read/write defines in encoding.h riscv: bootm: Pass mhartid CSR value to kernel riscv: Make start.S available for all targets riscv: ae350: Clean up mixed tabs and spaces in the dts riscv: kconfig: Select DM and OF_CONTROL riscv: Add QEMU virt board support riscv: Move do_reset() to a common place arch/Kconfig | 5 +- arch/riscv/Kconfig | 10 +- arch/riscv/Makefile | 3 +- arch/riscv/config.mk | 9 +- arch/riscv/cpu/Makefile | 7 ++ arch/riscv/cpu/ax25/Makefile | 2 - arch/riscv/cpu/ax25/cpu.c | 9 -- arch/riscv/cpu/cpu.c | 49 ++++++++ arch/riscv/cpu/qemu/Makefile | 6 + arch/riscv/cpu/qemu/cpu.c | 21 ++++ arch/riscv/cpu/qemu/dram.c | 17 +++ arch/riscv/cpu/{ax25 => }/start.S | 0 arch/riscv/cpu/{ax25 => }/u-boot.lds | 60 +++++----- arch/riscv/dts/ae350.dts | 177 +++++++++++++++-------------- arch/riscv/include/asm/bootm.h | 13 --- arch/riscv/include/asm/csr.h | 124 ++++++++++++++++++++ arch/riscv/include/asm/encoding.h | 50 +------- arch/riscv/include/asm/mach-types.h | 29 ----- arch/riscv/include/asm/setup.h | 194 -------------------------------- arch/riscv/include/asm/u-boot.h | 1 - arch/riscv/lib/Makefile | 1 + arch/riscv/lib/bootm.c | 20 +--- arch/riscv/lib/reset.c | 14 +++ board/AndesTech/ax25-ae350/ax25-ae350.c | 2 - board/emulation/qemu-riscv/Kconfig | 21 ++++ board/emulation/qemu-riscv/MAINTAINERS | 7 ++ board/emulation/qemu-riscv/Makefile | 5 + board/emulation/qemu-riscv/qemu-riscv.c | 23 ++++ cmd/bdinfo.c | 1 - configs/ax25-ae350_defconfig | 2 - configs/qemu-riscv32_defconfig | 10 ++ configs/qemu-riscv64_defconfig | 11 ++ doc/README.qemu-riscv | 46 ++++++++ include/configs/qemu-riscv.h | 21 ++++ 34 files changed, 532 insertions(+), 438 deletions(-) create mode 100644 arch/riscv/cpu/Makefile create mode 100644 arch/riscv/cpu/cpu.c create mode 100644 arch/riscv/cpu/qemu/Makefile create mode 100644 arch/riscv/cpu/qemu/cpu.c create mode 100644 arch/riscv/cpu/qemu/dram.c rename arch/riscv/cpu/{ax25 => }/start.S (100%) rename arch/riscv/cpu/{ax25 => }/u-boot.lds (54%) delete mode 100644 arch/riscv/include/asm/bootm.h create mode 100644 arch/riscv/include/asm/csr.h delete mode 100644 arch/riscv/include/asm/mach-types.h delete mode 100644 arch/riscv/include/asm/setup.h create mode 100644 arch/riscv/lib/reset.c create mode 100644 board/emulation/qemu-riscv/Kconfig create mode 100644 board/emulation/qemu-riscv/MAINTAINERS create mode 100644 board/emulation/qemu-riscv/Makefile create mode 100644 board/emulation/qemu-riscv/qemu-riscv.c create mode 100644 configs/qemu-riscv32_defconfig create mode 100644 configs/qemu-riscv64_defconfig create mode 100644 doc/README.qemu-riscv create mode 100644 include/configs/qemu-riscv.h -- 2.7.4

[U-Boot] [ANN] U-Boot v2018.09 released
by Tom Rini 10 Sep '18

10 Sep '18

Hey all, It's release day, and here we are doing the release. It's live on git (I hope) and FTP and ACD (along with the PGP sig file). So with the v2018.07 release I mentioned various migration deadlines. We're closer to being able to call migrations done, but not quite. There's a few changes I can pull in just after release, but we also still have work to be done for both BLK and DM_SPI. Now as I mentioned back in June[1] I'd really like to see more signed tags for pull requests as that means there's a changelog I can read over when making release emails. So, from summarizing the tags: - Xilinx platforms (zynq, zynqmp, microblaze) have cleaned up and improved a number of areas with better DT and sysreset functionality. A number of drivers have been converted to DM. - EFI support has had a number of corrections made due to running SCT. - ARC has updated some of their drivers and now supports gcc-8.1.x And a few more specific things in all cases can be seen with: git log --merges v2018.07..v2018.09 Thanks all!

[U-Boot] [PATCH] mtd: nand: denali: fix unaligned cache operation warnings on ARMv7 SoCs
by Masahiro Yamada 10 Sep '18

10 Sep '18

If the OOB size is not multiple of the cache line size, the ARMv7 cache operation still warns "Misaligned operation at range". The real cache coherency problem was fixed by commit e3332e1a1a04 ("Make kmalloc'ed memory really DMA-safe"). Now it is the matter of the warning messages. => nand info Device 0: nand0, sector size 256 KiB Page size 4096 b OOB size 224 b Erase size 262144 b subpagesize 4096 b options 0x00104200 bbt options 0x00060000 => nand dump 0 CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] CACHE: Misaligned operation at range [9fb15280, 9fb16360] ...

[U-Boot] [PATCH] fdt: fix get_next_memory_node()
by Marek Vasut 10 Sep '18

10 Sep '18

The get_next_memory_node() always sets mem to -1 , which is incorrect, because then every iteration of memory bank parsing will start from the first memory bank instead of the previous one. On systems with 1 memory bank defined in DT and CONFIG_NR_DRAM_BANKS=4 , like ie. r8a77965-salvator-x , this will result in U-Boot incorrectly reporting four identical memory banks with the same memory configuration. Fix this by setting mem to startoffset value, which restores the behavior before the fixed patch was applied.

[U-Boot] kgdb support for aarch64 architecture based boards
by Korimella Raja Sekhar Reddy 10 Sep '18

10 Sep '18

Hi All, I am planning to understand & work on kgdb stubs on u-boot for aarch64 architecture. Is anyone working on it and are they have any progress / stubs done for the aarch64. I saw there are stubs in u-boot directory for 'power pc' architecture. I am planning to bring the similar way of stubs for armv8, aarch64 architecture. Please let me know if you have any information related to kgdb (for u-boot) / current stage of development of kgdb support if any. One clarification is that, if I brought the kgdb stubs on u-boot, it will be helpful until it loads the Kernel and once the control handovers to kernel to load the actual OS, kgdb won't be work it out am I correct. Can I use the same kgdb stub to do debug of standalone applications from u-boot. Thanks, Korimella
