[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

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.

This patch enables networking support for TI's J721e SoC. Patch 1 adds a new interface to DMA uclass to get channel specific private/configuration data. Patch 2 to 4 use this interface to pass data from J721e's UDMA driver to CPSW ethernet driver. Last two patches add DMA and CPSW DT nodes and configs.

[U-Boot] [PATCH] net: eth-uclass: ignore unavailable devices
by Michael Walle 02 Dec '19

02 Dec '19

device_probe() may fail in which case the seq_id will be -1. Don't display these devices during startup. While this is only a cosmetic change, the return value of eth_initialize() will also change to the actual number of available devices. The return value is only used in spl_net to decide whether there are any devices to boot from. So returning only available devices is also more correct in that case.
