[U-Boot] [RESEND PATCH] net: tftp: Fix tftp store address check in store_block()
by Bin Meng 02 Dec '19

02 Dec '19

During testing of qemu-riscv32 with a 2GiB memory configuration, tftp always fails with a error message: Load address: 0x84000000 Loading: # TFTP error: trying to overwrite reserved memory... It turns out the result of 'tftp_load_addr + tftp_load_size' just overflows (0x100000000) and the test logic in store_block() fails. Fix this by adjusting the end address to ULONG_MAX when overflow is detected.

[U-Boot] [PATCH v4 1/2] common: Add support for Android DT image
by Sam Protsenko 02 Dec '19

02 Dec '19

Android documentation recommends new image format for storing DTB/DTBO files: [1]. To support that format, this patch adds helper functions for Android DTB/DTBO format. In image-android-dt.* files you can find helper functions to work with Android DT image format, such us routines for: - printing the dump of image structure - getting the address and size of desired dtb/dtbo file This patch uses dt_table.h file, that was added in commit 643cefa4d848 ("Import Android's dt_table.h for DT image format") by Alex Deymo. [1] https://source.android.com/devices/architecture/dto/partitions Signed-off-by: Sam Protsenko <semen.protsenko(a)linaro.org> --- Changes in v4: - fix SPDX tags - renamed .reserved[] to .version (just reflect changes in dt_image.h) Changes in v3: - dropped include/dt_image.h (was sent in another patch by Alex Deymo) - rebased on top of last master common/image-android-dt.c | 156 +++++++++++++++++++++++++++++++++++++ include/image-android-dt.h | 20 +++++ 2 files changed, 176 insertions(+) create mode 100644 common/image-android-dt.c create mode 100644 include/image-android-dt.h diff --git a/common/image-android-dt.c b/common/image-android-dt.c new file mode 100644 index 0000000000..c0683ee70f --- /dev/null +++ b/common/image-android-dt.c @@ -0,0 +1,156 @@ +// SPDX-License-Identifier: GPL-2.0+ +/* + * (C) Copyright 2018 Linaro Ltd. + * Sam Protsenko <semen.protsenko(a)linaro.org> + */ + +#include <image-android-dt.h> +#include <dt_table.h> +#include <common.h> +#include <linux/libfdt.h> +#include <mapmem.h> + +/** + * Check if image header is correct. + * + * @param hdr_addr Start address of DT image + * @return true if header is correct or false if header is incorrect + */ +bool android_dt_check_header(ulong hdr_addr) +{ + const struct dt_table_header *hdr; + u32 magic; + + hdr = map_sysmem(hdr_addr, sizeof(*hdr)); + magic = fdt32_to_cpu(hdr->magic); + unmap_sysmem(hdr); + + return magic == DT_TABLE_MAGIC; +} + +/** + * Get the address of FDT (dtb or dtbo) in memory by its index in image. + * + * @param hdr_addr Start address of DT image + * @param index Index of desired FDT in image (starting from 0) + * @param[out] addr If not NULL, will contain address to specified FDT + * @param[out] size If not NULL, will contain size of specified FDT + * + * @return true on success or false on error + */ +bool android_dt_get_fdt_by_index(ulong hdr_addr, u32 index, ulong *addr, + u32 *size) +{ + const struct dt_table_header *hdr; + const struct dt_table_entry *e; + u32 entry_count, entries_offset, entry_size; + ulong e_addr; + u32 dt_offset, dt_size; + + hdr = map_sysmem(hdr_addr, sizeof(*hdr)); + entry_count = fdt32_to_cpu(hdr->dt_entry_count); + entries_offset = fdt32_to_cpu(hdr->dt_entries_offset); + entry_size = fdt32_to_cpu(hdr->dt_entry_size); + unmap_sysmem(hdr); + + if (index > entry_count) { + printf("Error: index > dt_entry_count (%u > %u)\n", index, + entry_count); + return false; + } + + e_addr = hdr_addr + entries_offset + index * entry_size; + e = map_sysmem(e_addr, sizeof(*e)); + dt_offset = fdt32_to_cpu(e->dt_offset); + dt_size = fdt32_to_cpu(e->dt_size); + unmap_sysmem(e); + + if (addr) + *addr = hdr_addr + dt_offset; + if (size) + *size = dt_size; + + return true; +} + +#if !defined(CONFIG_SPL_BUILD) +static void android_dt_print_fdt_info(const struct fdt_header *fdt) +{ + u32 fdt_size; + int root_node_off; + const char *compatible = NULL; + + fdt_size = fdt_totalsize(fdt); + root_node_off = fdt_path_offset(fdt, "/"); + if (root_node_off < 0) { + printf("Error: Root node not found\n"); + } else { + compatible = fdt_getprop(fdt, root_node_off, "compatible", + NULL); + } + + printf(" (FDT)size = %d\n", fdt_size); + printf(" (FDT)compatible = %s\n", + compatible ?

[U-Boot] One u-boot.bin for Raspberry PI 3 and 4 - possible?
by Geoff Williams 02 Dec '19

02 Dec '19

Hi List, TLDR: As subject I've been following Alexander Graf's uEFI+grub2 presentation on Raspberry PI[1]. I have it working on PI 3 and 4 and its great but I need to re-compile u-boot for each board which means lots of images. I would like create a single image to boot grub on PI 3 and 4. I did my own investigation but hit a wall. In board/raspberrypi/rpi/rpi.c there is a #IFNDEF..#ELSE around the definition of bcm283x_mem_map which selects a different memory layout to expose as extern struct mem_map for PI 4 vs anything else. I did some hacking to expose two mem_map extern structs and pick the right one at runtime[2]. Of course this experiment is horrible and breaks all other boards: board/raspberrypi/rpi/rpi.c static uint32_t rev_type;// = 0x11; struct mm_region *mem_map_b = other_bcm283x_mem_map; /* other PIs */ struct mm_region *mem_map_a = bcm2711_bcm283x_mem_map; /* PI 4 */ uint32_t get_rpi_hw_ref(void) { /* doesn't work get_board_rev(); */ return rev_type; } arch/arm/cpu/armv8/cache_v8.c /* before every use of mem_map... */ /* nasty hack */ struct mm_region *mem_map; if (get_rpi_hw_ref() == 0x11) { mem_map = mem_map_a; } else { mem_map = mem_map_b; } rev_type gets set by get_board_rev() but I don't believe this function has been called before mem_map is used[3] so my hack always chooses the else branch. I'm new to bootloader programming and waiting for a serial cable to arrive so am working blind but I suspect I'm up against some kind of chicken and egg problem where the memory map needs to be set before the board revision can be extracted using the mailbox driver, is anyone able to confirm this or suggest another approach? My dream is to be able to compile a single u-boot.bin compiled as armv8-a and be able to boot any Raspberry PI 3/4 to grub2 from it. Is this realistic? Cheers, Geoff [1] https://www.youtube.com/watch?v=bNL1pd-rwCU [2] https://github.com/GeoffWilliams/u-boot/tree/nasty [3] If I initialise rev_type as 0x11 then it works on Raspberry PI 4 but if its commented boot fails with rainbow screen which tells me that rev_type wasn't assigned (or didn't contain 0x11...?) before mem_map was used.

[U-Boot] [PATCH v2 0/6] Introduce DSA Ethernet switch class and Felix driver
by Alex Marginean 02 Dec '19

DSA stands for Distributed Switch Architecture and it is a subsystem introduced in the Linux kernel to support switches that: - have an Ethernet link up to the CPU - use some form of tagging to identify the source/destination port for Rx/Tx - may be cascaded in tree-like structures. DSA is described in depth here: https://www.kernel.org/doc/Documentation/networking/dsa/dsa.txt >From the doc: Summarized, this is basically how DSA looks like from a network device perspective: |--------------------------- | CPU network device (eth0)| ---------------------------- | <tag added by switch | | | | | | tag added by CPU> | |--------------------------------------------| | Switch driver | |--------------------------------------------| || || || |-------| |-------| |-------| | sw0p0 | | sw0p1 | | sw0p2 | |-------| |-------| |-------| This patch set introduces a DSA class in U-Boot to support drivers of such switches. DSA drivers have to implement the following ops: - enable/disable of switch ports, - insert a tag in frames being transmitted, used by the switch to select the egress port, - parse a tag in frames being received, used for Rx traffic. DSA class code deals with presentation of switch ports as Ethernet interfaces, deals with the master Ethernet device for I/O and helps with parsing of the DT assuming the structure follows the DSA kernel binding. Support for switch cascading is not included yet. This patch set also introduces a driver for the Ethernet switch integrated into NXP LS1028A, called Felix. The switch has 4 front panel ports, I/O to/fom it is done though an ENETC Ethernet interface and meta-data is carried between the switch and the driver though an additional header pre-pended to the original frame. Network commands like tftp can be used on these front panel ports. The ports are disabled unless used so they do not cause issues on network topologies that include loops.
