[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] xyz-modem: Change getc timeout loop waiting
by Tomas Melin 02 Aug '18

02 Aug '18

This fixes the loop delay when using a hw watchdog. In case a watchdog is used that accesses CPU registers, the defined delay of 20us in a tight loop will cause a huge delay in the actual timeout seen. This is caused by the fact that udelay will inheritantly call WATCHDOG_RESET. Together with the omap wdt implementation, the seen timeout increases up to around 30s. This makes the loop very slow and causes long delays when using the modem. Instead, implement the 2 sec loop by using the timer interface to know when to break out of the timeout loop. Watchdog kicking is taken care of by getc().

[U-Boot] [PATCH v3 00/10] driver model bring-up of musb on AM335x GP and BBB
by Mugunthan V N 26 Mar '18

26 Mar '18

This patch series enables musb driver to adopt driver model. This has been tested on the following evms (logs [1]) by loading kernel and dtbs from usb mass storage (host) and usb rndis mode (device). * AM335x GP evm * AM335x BBB Also pushed a branch for testing [2] This patch series depends on the following patch series * usb ether gadget DM conversion [4] Changes from v2: * Removed from non-useful error logs. * Since defconfig is merged into single defconfig for all TI AM335x platforms, rebased those patches as well. Changes from initial version: * Separated out the usb gadget driver patches from earlier musb series [3] for testing and submitting of dwc3 dm musb patches. * passed an dummy dev pointer for non-DM case as well for reducing the number of #ifdefs in musb backend driver.
