[U-Boot] [PATCH v4 0/3] Amlogic Meson GXBaby and ODROID-C2 support
by Beniamino Galvani 25 Apr '16

25 Apr '16

Hi, this series adds a very basic support for Amlogic S905 SoC (GXBaby) and for the ODROID-C2 board [1], and is based on u-boot sources available from the board vendor [2]. At the moment the only supported devices are the integrated UART and Ethernet adapter. Changes since v3: - designware eth: added check that buffer addresses are in first 4GiB as suggested by Marek (and thus removed the ack tags) - consolidated pinmux and gpio macros - used get_unaligned_be64() to avoid alignment faults in dram_init() - uint32_t -> u32 in serial_meson.c - implemented reboot and read from e-fuse through secure monitor Changes since v2: - squashed all platform patches into a single one - got rid of additional non-upstream DTS node for ethernet - improved board README - added macros for SoC registers fields Changes since v1: - updated DTS files from Linux kernel - added Ethernet support - first 16MiB of RAM are now marked as unavailable; this seems to be required to successfully boot Linux - fixed typo in config file [1] http://www.hardkernel.com/main/products/prdt_info.php?g_code=G145457216438 [2] https://github.com/hardkernel/u-boot/tree/odroidc2-v2015.01 Beniamino Galvani (3): net: designware: fix descriptor layout and warnings on 64-bit archs arm: add initial support for Amlogic Meson and ODROID-C2 arm: meson: implement calls to secure monitor arch/arm/Kconfig | 5 + arch/arm/Makefile | 1 + arch/arm/dts/Makefile | 2 + arch/arm/dts/meson-gxbb-odroidc2.dts | 69 +++++++++++++ arch/arm/dts/meson-gxbb.dtsi | 178 +++++++++++++++++++++++++++++++++ arch/arm/include/asm/arch-meson/gxbb.h | 52 ++++++++++ arch/arm/include/asm/arch-meson/sm.h | 13 +++ arch/arm/mach-meson/Kconfig | 31 ++++++ arch/arm/mach-meson/Makefile | 7 ++ arch/arm/mach-meson/board.c | 67 +++++++++++++ arch/arm/mach-meson/sm.c | 71 +++++++++++++ board/hardkernel/odroid-c2/Kconfig | 12 +++ board/hardkernel/odroid-c2/MAINTAINERS | 6 ++ board/hardkernel/odroid-c2/Makefile | 7 ++ board/hardkernel/odroid-c2/README | 60 +++++++++++ board/hardkernel/odroid-c2/odroid-c2.c | 67 +++++++++++++ configs/odroid-c2_defconfig | 23 +++++ drivers/net/designware.c | 59 ++++++----- drivers/net/designware.h | 4 +- drivers/serial/Kconfig | 15 +++ drivers/serial/Makefile | 1 + drivers/serial/serial_meson.c | 162 ++++++++++++++++++++++++++++++ include/configs/odroid-c2.h | 55 ++++++++++ 23 files changed, 938 insertions(+), 29 deletions(-) create mode 100644 arch/arm/dts/meson-gxbb-odroidc2.dts create mode 100644 arch/arm/dts/meson-gxbb.dtsi create mode 100644 arch/arm/include/asm/arch-meson/gxbb.h create mode 100644 arch/arm/include/asm/arch-meson/sm.h create mode 100644 arch/arm/mach-meson/Kconfig create mode 100644 arch/arm/mach-meson/Makefile create mode 100644 arch/arm/mach-meson/board.c create mode 100644 arch/arm/mach-meson/sm.c create mode 100644 board/hardkernel/odroid-c2/Kconfig create mode 100644 board/hardkernel/odroid-c2/MAINTAINERS create mode 100644 board/hardkernel/odroid-c2/Makefile create mode 100644 board/hardkernel/odroid-c2/README create mode 100644 board/hardkernel/odroid-c2/odroid-c2.c create mode 100644 configs/odroid-c2_defconfig create mode 100644 drivers/serial/serial_meson.c create mode 100644 include/configs/odroid-c2.h -- 2.7.3

[U-Boot] [PATCH v2] i2c: muxes: Add support for TI PCA954X mux
by Michal Simek 25 Apr '16

25 Apr '16

Add support for common TI i2c mux which is available on ZynqMP zcu102 board. DM i2c mux core code is selecting/deselecting bus before/after every command is performed that's why only one channel is active at a time. That's also the reason why deselect is just disable all available channels.

[U-Boot] Fresh New Soc+Board port with Driver Model
by Neil Armstrong 25 Apr '16

25 Apr '16

Hi, I want to start an U-Boot port to a custom Uniprocessor Cortex-A9 based SoC to boot a Device Tree enabled 4.4 kernel, but I'm struggling to find a good starting point/example code in order to do it "the right way". I was present at the Dublin's ELC prosentation on Driver Model, and it seems accurate to directly use it. Can someone give me some hint of an actual upstream board support that has the full Driver Model and SPL enabled ? Thanks, Neil

[U-Boot] [ANN] U-Boot v2016.05-rc2 released
by Tom Rini 25 Apr '16

25 Apr '16

Hey all, As promised, and only slightly late, here's -rc2. I've picked up a bunch of things that were outstanding and I had grabbed in patchwork and I felt should come in now rather than wait for the next window. There's some good work going on in SPL land that I'm going to let wait since we aren't quite able to make real use of it yet but I'm otherwise happy with. I forgot to mention this with -rc1 but I'm going to mention it again now like I had intended to anyhow. For ARM platforms, the EFI loader code is enabled by default. I'm quite happy to see people turn it off if they believe their board has no use case for it but as I think this will help the out of box experience for many end users I'm of the opinion it should default to on, not off. Thanks all! -- Tom

[U-Boot] Fwd: U-boot xHCI endianes issues

Hi All, I am running u-boot on ARMv7 - 32 bit in Big Endian mode. Intially, i was stuck while enumerating the mass storage device after port change event. But changing the below @ line 400 in "xhci-mem.c" @ http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/usb/host/xhci-mem.c;h=374… . Note:It was also highlighted by Aaron. /* Point to output device context in dcbaa. */ ctrl->dcbaa->dev_context_ptrs[slot_id] = byte_64; TO /* Point to output device context in dcbaa. */ ctrl->dcbaa->dev_context_ptrs[slot_id] = cpu_to_le64(byte_64); Solved it... Now the enumeration all happened successfully. After which the first Bulk transfer is failing with following error msg: "XHCI bulk transfer timed out, aborting...\n" I doubt, i am still missing few more "le to be" conversion which are not part of latest uboot code Request ur help. Regards Mohamed Mohisin

[U-Boot] [PATCH] distro: Disable iso partition format for SPL

When building an SPL binary, chances are quite slim that we need an iso partition label. However, there were reports of us exceeding our SPL memory limit with iso enabled. So for now, let's disable the ISO partition format code when in the SPL build.
