[U-Boot] [ubiblock PATCH] Read-only block driver on top of UBI volumes
by Juha Sarlin 28 Dec '19

28 Dec '19

Add "ubi block" command to create a block device on top of a UBI volume. This block device can be used with some U-Boot commands, eg: fstype, ls and load. Example use: => ubi part fs => ubi block root root dev=0 => fstype ubi 0 squashfs ubiblock_read() is based on drivers/mtd/ubi/block.c from Linux 4.19.75.

[U-Boot] [PATCH 0/2] Add support for booting EFI FIT images
by Cristian Ciocaltea 27 Dec '19

27 Dec '19

Currently the only way to run an EFI binary like GRUB2 is via the 'bootefi' command, which cannot be used in a verified boot scenario. The obvious solution to this limitation is to add support for booting FIT images containing those EFI binaries. The implementation relies on a new image type - IH_OS_EFI - which can be created by using 'os = "efi"' inside an ITS file: / { #address-cells = <1>; images { efi-grub { description = "GRUB EFI"; data = /incbin/("EFI/BOOT/bootarm.efi"); type = "kernel_noload"; arch = "arm"; os = "efi"; compression = "none"; load = <0x0>; entry = <0x0>; hash-1 { algo = "sha256"; }; }; }; configurations { default = "config-grub"; config-grub { kernel = "efi-grub"; signature-1 { algo = "sha256,rsa2048"; sign-images = "kernel"; }; }; }; }; The bootm command has been extended to handle the IH_OS_EFI images. To enable this feature, a new configuration option has been added: BOOTM_EFI I tested the solution using the 'qemu_arm' board: => load scsi 0:1 ${kernel_addr_r} efi-image.fit => bootm ${kernel_addr_r}#config-grub Cristian Ciocaltea (2): image: Add IH_OS_EFI for EFI chain-load boot bootm: Add a bootm command for type IH_OS_EFI cmd/Kconfig | 9 ++++++++- cmd/bootefi.c | 2 +- common/bootm_os.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ common/image-fit.c | 3 ++- common/image.c | 1 + include/bootm.h | 2 ++ include/image.h | 1 + 7 files changed, 59 insertions(+), 3 deletions(-) -- 2.17.1

how to efficiently add a vendor zynqmp board stealing from xilinx/ dir?
by Robert P. J. Day 27 Dec '19

27 Dec '19

short form: is there an efficient way to add a new vendor and new zynqmp-based board to the u-boot infrastructure without creating a whole new vendor directory that (mostly) duplicates what is already under board/xilinx/? as i read it, if i configure u-boot for, say, a xilinx zynqmp-based ZCU102 (rev 1.0), the "board" selection is actually just the SoC specifier -- in this case, zynqmp. the resulting .config file contains, among other stuff: CONFIG_SYS_ARCH="arm" CONFIG_SYS_CPU="armv8" CONFIG_SYS_SOC="zynqmp" CONFIG_SYS_VENDOR="xilinx" CONFIG_SYS_BOARD="zynqmp" CONFIG_SYS_CONFIG_NAME="xilinx_zynqmp" with no indication of the actual (ZCU102) target board. again, as i read it, the board-specific content comes from: 1) the board defconfig file, say: $ make xilinx_zynqmp_zcu102_rev1_0_defconfig 2) the board/xilinx/zynqmp/ subdirectory identified by CONFIG_DEFAULT_DEVICE_TREE="zynqmp-zcu102-rev1.0" with most of those xilinx/zynqmp/ subdirectories containing the single (board-specific) source file psu_init_gpl.c. in other words, it *seems* that a new zynqmp-based board can be entirely defined by (in the simple case): 1) an appropriate defconfig file 2) a board-specific psu_init_gpl.c file now, if i wanted to define a new vendor and board as above (say, vendor "acme" and board "coyote" rev 1.0, based on ZCU102), i could of course just create an entirely new vendor directory and copy all of the relevant content from board/xilinx/ into it, but most of that would be identical. is there an obvious way to somehow "steal" the xilinx vendor content so that i don't have to copy it? copying it would naturally be the most obvious strategy, just wondering if there is a more clever way to base the new vendor and board off the board/xilinx/ content. (symlinks would also work, i guess, but that just seems messy.) i'm guessing there's no clever way to do this, but i'm willing to be corrected. rday

[PATCH v5 0/8] Add a random number generator uclass
by Sughosh Ganu 27 Dec '19

27 Dec '19

Add a random number generator(rng) uclass to facilitate adding drivers for rng devices. I plan to add an implementation of the EFI_RNG_PROTOCOL, which would get the random number from the rng uclass -- the protocol would be used by the efi stub for getting a random number for the kaslr feature. The patch series also adds a driver for the rng device found on the stm32mp1 and qemu platforms. A dummy rng driver for sandbox has also been added, along with the unit test for the rng uclass. Changes since V4: * Get the read functions of individual drivers to return number of bytes read on successful read, and a -ve value on error. * Handle review comments from Heinrich Schuchardt. Changes since V3: * Handle review comments from Patrick Delaunay Changes since V2: * Add a driver for the virtio-rng device on qemu platform Changes since V1: * Add a SPDX header in rng.h * Change the UCLASS_DRIVER name from hwrng to rng, consistent with the rest of the naming convention * Handle review comment from Patrice Chotard Sughosh Ganu (8): dm: rng: Add random number generator(rng) uclass clk: stm32mp1: Add a clock entry for RNG1 device stm32mp1: rng: Add a driver for random number generator(rng) device configs: stm32mp15: Enable random number generator(rng) device sandbox: rng: Add a random number generator(rng) driver configs: sandbox: Enable random number generator(rng) device test: rng: Add basic test for random number generator(rng) uclass virtio: rng: Add a random number generator(rng) driver arch/sandbox/dts/test.dts | 4 + configs/sandbox64_defconfig | 2 + configs/sandbox_defconfig | 2 + configs/stm32mp15_basic_defconfig | 2 + configs/stm32mp15_optee_defconfig | 2 + configs/stm32mp15_trusted_defconfig | 2 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/clk/clk_stm32mp1.c | 1 + drivers/rng/Kconfig | 22 +++++ drivers/rng/Makefile | 8 ++ drivers/rng/rng-uclass.c | 23 +++++ drivers/rng/sandbox_rng.c | 56 ++++++++++++ drivers/rng/stm32mp1_rng.c | 165 ++++++++++++++++++++++++++++++++++++ drivers/virtio/Kconfig | 6 ++ drivers/virtio/Makefile | 1 + drivers/virtio/virtio-uclass.c | 1 + drivers/virtio/virtio_rng.c | 85 +++++++++++++++++++ include/dm/uclass-id.h | 1 + include/rng.h | 33 ++++++++ include/virtio.h | 4 +- test/dm/Makefile | 1 + test/dm/rng.c | 26 ++++++ 23 files changed, 449 insertions(+), 1 deletion(-) create mode 100644 drivers/rng/Kconfig create mode 100644 drivers/rng/Makefile create mode 100644 drivers/rng/rng-uclass.c create mode 100644 drivers/rng/sandbox_rng.c create mode 100644 drivers/rng/stm32mp1_rng.c create mode 100644 drivers/virtio/virtio_rng.c create mode 100644 include/rng.h create mode 100644 test/dm/rng.c -- 2.7.4

[PATCH 0/3] Ethernet support for Raspberry Pi 4
by Andre Przywara 27 Dec '19

27 Dec '19

This series adds Ethernet support for the Raspberry Pi 4. The SoC includes a "Broadcom Genet v5 MAC" IP, connected as a proper platform device (no USB anymore!). Patch 1 provides a driver for that. There does not seem to be publicly available documentation, so this is based on the Linux driver, but stripped down to just provide what U-Boot needs. Patch 2 fixes up the RPi4 memory map to accommodate the MMIO area the MAC lives in, while patch 3 enables it in the respective defconfigs. Compared to the RFC post from Friday this is now fully functional, although there are some minor issues left (sometimes unstable initialisation, weird behaviour on repeated tftp gets (though it works), PHY startup not properly timing out, (unjustified?) cache complaints on 32-bit). Please have a look and test it, I hope this helps to simplify development, as you spare the SD card and its slot from heavy swapping. This tries to address the review comments on the RFC post (mostly my own ;-), I put a branch on [1] showing what was changed over the original post. Cheers, Andre. P.S.: Since Amit will be busy this week, I took the freedom of fixing this up and posting this (with his permission).

Bad CRC for ramdisk when using large rootfs
by Yusuf Altıparmak 27 Dec '19

27 Dec '19

Hello, I Have a demo board which has 8 GB ram. Trying to boot with ramdisk. When I use large size ramdisk image (447.8 MiB), it's giving Bad CRC while verifying checksum. When I use small size (49 MiB) its verifiying successfully. What is the reason of it ? The commands I use are, tftp 2000000 uImage-------.bin tftp 4000000 -------------.dtb tftp 1000000000 ----------.rootfs.ext2.gz.u-boot bootm 2000000 1000000000 4000000 u-boot logs are, WARNING: adjusting available memory to 30000000 ## Booting kernel from Legacy Image at 02000000 ...

[PATCH v4 0/3] mkimage/rockchip: support packing optional second level boot-loader

When enabling back-to-bootrom, the bootrom would continue to load the second level boot-loader. And currently we are packing it by appending the generated image manually (with a predefined max size): ./firefly-rk3288/tools/mkimage -n rk3288 -T rksd -d \ firefly-rk3288/spl/u-boot-spl-dtb.bin out && \ cat firefly-rk3288/u-boot-dtb.bin >> out This series add support of packing optional second level loader with mkimage tool: ./tools/mkimage -n rk3399 -T rksd -d \ rk3399_ddr_800MHz_v1.24.bin:rk3399_miniloader_v1.19.bin out Changes in v4: Remove unused variable ‘spl_size’. Changes in v3: Rule out hdr when checking spl size. (The bootrom would put hdr on stack.) Changes in v2: Do rc4 encode for boot data when needed as well.
