[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] armv5 and OMAP3 Question
by Adam Ford 04 Aug '18

04 Aug '18

The readme file for OMAP indicates that we compile using armv5 to "to allow more compilers to work" We have our arch/arm/mach-omap2/omap3/lowlevel_init.S file also noting some special assembly insturctions becuse we use armv5. The barriers defined also indicate we're using CP15 instead of the separate barrier instructions for armv7 because we're using armv5 instead. I just wonder in this day and age when we're noting a GCC version and generating warnings based on the GCC warning, do we still need to compile as armv5 any more? It seems like "to allow more compilers to work" would not really apply any more we're trying to push newer versions of GCC. (please don't flame me, I am honestly curious). adam

[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] sunxi: reduce Orange Pi Zero DRAM clock speed
by Clément Bœsch 31 May '18

31 May '18

Using `fel-boot-lima-memtester-on-orange-pi-pc 672` on an Orange Pi without heatsink results in the following error after a few minutes: WRITE FAILURE: 0x00200000 != 0xffdfffff at offset 0x0137f47c (bitflip). Also, the constructor repository (github/orangepi-xunlong) seems to contain that 624 Mhz clock speed in its u-boot fork. It may be that 672 Mhz is the advertized overclocked speed. According to http://linux-sunxi.org/Orange_Pi_PC#DRAM_clock_speed_limit it may be worth decreasing that value with other Orange Pi boards.
