[U-Boot] Starting u-boot in USB otg mode
by rivael_il 27 Feb '20

27 Feb '20

Hello u-booters! I want to load u-boot-sunxi-with-spl.bin and make it operate the USB in otg mode. (Where the host can still be connected to the board). How can I achieve this? (I have attempted to use: "usb0:dr_mode=otg,phy_type=utmi\0" without success). Thank you, Michael

[U-Boot] [PATCH 0/10] x86: Add generic VESA video driver
by Simon Glass 01 Aug '19

01 Aug '19

This series introduces a generic VESA video driver and adjusts the generic PCI ROM support to support it. It also fixes up some problems which prevent this from working on PowerPC at present. It is now possible to use VESA graphics: - On PowerPC, using the x86 emulator - On x86, using either the x86 emulator or native code execution As it turns out, on the only platform I have tested (link), the x86 emulator is only slightly slower that native code execution (200ms difference). Still, we may as well leave this feature in there. VGA ROMs are a very old technology but they are still used by modern platforms, including at least link and some Atom designs. Simon Glass (10): bios_emulator: Fix an #ifdef typo in the header file x86: Correct endianness isues in pci_rom x86: Support ROMs on other archs bios_emulator: Don't display error when emulator terminates bios_emulator: Add some VESA interface debugging x86: pci: Don't stop when we get a vendor/device mismatch x86: Add a VESA video driver x86: Drop the x86_fb driver x86: Access the VGA ROM when needed RFC: Test code for glacier PCI video support arch/x86/include/asm/u-boot-x86.h | 2 + drivers/bios_emulator/atibios.c | 161 +++++++++++++++++++++++---- drivers/bios_emulator/include/x86emu/debug.h | 2 +- drivers/bios_emulator/x86emu/ops.c | 2 +- drivers/pci/pci_auto.c | 28 ++++- drivers/pci/pci_rom.c | 40 ++++--- drivers/video/Makefile | 2 +- drivers/video/vesa_fb.c | 64 +++++++++++ drivers/video/x86_fb.c | 38 ------- include/configs/canyonlands.h | 31 ++++++ include/configs/chromebook_link.h | 2 +- include/pci.h | 9 ++ include/pci_rom.h | 1 - include/vbe.h | 9 +- 14 files changed, 312 insertions(+), 79 deletions(-) create mode 100644 drivers/video/vesa_fb.c delete mode 100644 drivers/video/x86_fb.c -- 2.2.0.rc0.207.ga3a616c

[U-Boot] [PATCH 1/2] usb: gadget: fastboot: Request status and length check in rx handler
by Paul Kocialkowski 18 Mar '19

18 Mar '19

This avoids handling requests that have an error status or no data. In particular, this avoids showing unnecessary error messages when the USB gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB gadget driver sends an error back to the host (that has disconnected already).

[U-Boot] [PATCH] FSL PCI: Configure PCIe reference ratio
by Joakim Tjernlund 13 Aug '18

13 Aug '18

Most FSL PCIe controllers expects 333 MHz PCI reference clock. This clock is derived from the CCB but in many cases the ref. clock is not 333 MHz and a divisor needs to be configured. This adds PEX_CCB_DIV #define which can be defined for each type of CPU/platform.
