[U-Boot] efi_loader: Add distro boot script for removable media
by Stephen Warren 13 Apr '16

13 Apr '16

I've spotted a couple of problems in 74522c898b35 "efi_loader: Add distro boot script for removable media". These help explain something I found strange in the commit description of the recently sent patch "jetson-tk1: Set fdtfile environment variable"; "The 4.5.0 kernel cannot cope with U-Boot's internal device tree". > "load_efi_dtb=" \ > "load ${devtype} ${devnum}:${distro_bootpart} " \ > "${fdt_addr_r} ${prefix}${fdtfile}; " \ > "fdt addr ${fdt_addr_r}\0" \ > \ The "fdt addr" command shouldn't be there. That affects the DT that U-Boot's internal commands operate on internally. That is entirely unrelated to the the DT that is passed to the Linux kernel. Instead, the EFI code should pass the DTB at ${kernel_addr_r} to the kernel, just like all other boot mechanisms do. If by some chance U-Boot is configured by DTB and that DTB is fully suitable to pass to the Linux kernel, then the board-specific code can arrange for ${kernel_addr_r} to point at that same DTB, thus removing the need to load one. However, that's unlikely to happen too often at present; the most complete DTBs are housed in the Linux kernel source tree, and DTB ABI still isn't really a thing, so in practice one mostly wants to load a DTB that was built as part of the kernel being booted, and hence U-Boot's DTB isn't relevant.

[U-Boot] [PATCH] ARM: tegra: enable GPU node by compatible value
by Stephen Warren 13 Apr '16

13 Apr '16

From: Stephen Warren <swarren(a)nvidia.com> In current Linux kernel Tegra DT files, 64-bit addresses are represented in unit addresses as a pair of comma-separated 32-bit values. Apparently this is no longer the correct representation for simple busses, and the unit address should be represented as a single 64-bit value. If this is changed in the DTs, arm/arm/mach-tegra/board2.c:ft_system_setup() will no longer be able to find and enable the GPU node, since it looks up the node by name. Fix that function to enable nodes based on their compatible value rather than their node name. This will work no matter what the node name is, i.e for DTs both before and after any rename operation.

jetson-tk1 has 2 GB of RAM at 0x80000000, causing gd->ram_top to be zero. Handle this by replacing it with 0x100000000 in that case.

[U-Boot] Newbie SPL question for socfpga_sockit
by George Broz 13 Apr '16

13 Apr '16

Hello, Sorry for the newbie question... I have an Altera/Terasic board (socfpga_sockit) that has issues recognizing USB storage devices (roughly 60% good / 40% bad): SOCFPGA_CYCLONE5 # usb start (Re)start USB... USB0: scanning bus 0 for devices... DW_USB: Transfer completion interrupt timeout Timed out waiting for channel to disable 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found The pre-made U-Boot SPL & image that come with the board have version: U-Boot 2013.01.01 (Aug 08 2014 - 10:46:23) (Old!) I need to rebuild U-Boot for this board to add md5sum and hopefully fix the USB issues. When I've rebuilt the u-boot.img from the 2013.01.01 branch of the (Altera maintained) source, U-boot boots, but the USB problems get worse (100% bad): USB0: Core Release: 2.93a dwc_otg_core_host_init: Unable to clear halt on channel 1 (timeout HCCHAR 0xC0000000 @ffb40520) dwc_otg_core_host_init: Unable to clear halt on channel 2 (timeout HCCHAR 0xC0000000 @ffb40540 (I've confirmed that CONFIG_CMD_USB and CONFIG_USB_STORAGE are defined and have tried turning on and off 'dcache' as suggested elsewhere to no avail). If I try a later release (e.g. v2016.01 which seems to support the Terasic board explicitly) the boot process stops just after loading the SPL. At this point I have only been changing the u-boot.img component, not the SPL (in the a2 partition of the MMC). The documentation from Altera about generating the SPL seems to require using Qsys/Quartus tools which I'd really like to avoid. I can produce u-boot-spl.bin / u-boot.img from make socfpga_sockit_defconfig; make all. My newbie question ... should be I able to use directly the u-boot-spl.bin generated by the build to replace the SPL on the board? (I'm hoping the USB issues resolve themselves when I'm able to get the later version of U-Boot running...) Thanks for any input... --George Broz Moog Industrial Group
