[U-Boot] [PATCH] usb gadget: increase envstr size in cb_getvar
by Nicolas le bayon 10 Mar '17

10 Mar '17

Hi, I propose you this patch in order to take into account strings larger than actual size (32). I recently faced to 'fastboot.partition-type:userdata' (it was in Android context) but this could be the case for other purposes. I propose to simply double the size. Is it ok for you?

[U-Boot] [RFC] odroid: Add support for the ODROID-X board variant
by Siarhei Siamashka 07 Mar '17

07 Mar '17

ODROID-X uses a slightly older revision of the same base board as the ODROID-X2. But the CPU module in ODROID-X uses an older 1.4GHz revision of Exynos4412 SoC and less RAM (1GiB instead of 2GiB). The current U-Boot code deadlocks on ODROID-X when probing the RAM size via get_ram_size() function. Reducing CONFIG_NR_DRAM_BANKS from 8 to 4 can fix this problem. But this constant is used in a lot of places in U-Boot, while SDRAM_BANK_SIZE can be easily replaced with the code which relies on runtime detection of the board type. So we change 4 or 8 banks of 256MiB with just one fake bank of 2GiB or 1GiB. The runtime detection check tries to read the PRO_ID register in the hope that it might be different between Exynos4412 and Exynos4412 Prime and enough to detect the difference between X and X2 board variants. Signed-off-by: Siarhei Siamashka <siarhei.siamashka(a)gmail.com> --- I'm assuming that the X and X2 hardware is nearly identical and can be supported with a common code in U-Boot, based on the changelog of PCB revisions: http://com.odroid.com/sigong/blog/blog_list.php?bid=132 This is an RFC patch because I don't have an X2 board and can't test if checking the PRO_ID register is good enough. If it does not work, then maybe some other method could be tried (probe the DRAM controller registers?). Also does the number of DRAM banks have any special meaning on this platform in U-Boot and Linux (after the proprietary blob has already initialized the DRAM controller)? If this approach is wrong, then what would be the best way to add support for the ODROID-X board?

[U-Boot] [PATCH 00/29] blackfin: Add driver-model and device tree suport
by Simon Glass 23 Feb '17

23 Feb '17

At present the only serial driver that is not converted to driver mode is blackfin. As I recently obtained a suitable board from a kind donor I have decided to convert the driver over, as the unpalatable alternative would be to remove blackfin support from U-Boot. Blackfin's init sequence is someone non-standard. This series adjusts this to fit more with how things are now done, adds device-tree support, a serial driver and enables driver model on bf537-stamp. A few CONFIG options are dropped in this series also, as these were noticed along the way. Future work could enhance the serial driver to support v4 hardware and convert all boards to driver model. Simon Glass (29): blackfin: Drop CONFIG_SYS_MEMTEST_START/END fdt: Allow the device tree to be set up by board init code blackfin: Add a few useful linker symbols blackfin: Drop the extra blank line in the link script blackfin: Use compiler-generated symbols for BSS blackfin: Clear the BSS in C code blackfin: Add a memory region for pre-relocation data blackfin: Use generic board to set the stack address blackfin: Avoid using bd_info in print_cpuinfo() blackfin: Avoiding using P3 in early init blackfin: Allow cpu_init_f() to return blackfin: Drop CONFIG_STACKBASE tegra: Drop CONFIG_STACKBASE in favour of TEGRA_STACKBASE sparc: Drop CONFIG_SYS_MALLOC_BASE blackfin: Drop CONFIG_SYS_MALLOC_BASE Drop CONFIG_SYS_MALLOC_END blackfin: Call C code to relocate blackfin: Don't set global_data again blackfin: Set the RAM size separately from bd_info blackfin: Set up bd_info later blackfin: Copy the device tree out of BSS blackfin: Allow use of CONFIG_OF_CONTROL blackfin: bf537-stamp: Enable CONFIG_OF_CONTROL dm: serial: Reset the watchdog when outputting characters dm: serial: pxa: Drop pxa from the serial README dm: serial: Update the serial README dm: blackfin: Add a driver-model serial driver blackfin: Set up the debug UART if enabled blackfin: Enable driver-model on bf537-stamp arch/Kconfig | 1 + arch/blackfin/Kconfig | 9 ++ arch/blackfin/cpu/cpu.c | 69 +++++++------ arch/blackfin/cpu/start.S | 35 +++---- arch/blackfin/cpu/u-boot.lds | 24 ++++- arch/blackfin/dts/Makefile | 18 ++++ arch/blackfin/dts/bf537-stamp.dts | 11 +++ arch/blackfin/include/asm/config.h | 12 --- arch/blackfin/include/asm/serial1.h | 2 + arch/blackfin/include/asm/u-boot.h | 5 + arch/blackfin/lib/sections.c | 2 +- cmd/bdinfo.c | 2 - configs/bf537-stamp_defconfig | 8 ++ doc/driver-model/serial-howto.txt | 11 +-- drivers/serial/Kconfig | 8 ++ drivers/serial/serial-uclass.c | 2 + drivers/serial/serial_bfin.c | 192 ++++++++++++++++++++++++++++++++++++ include/configs/bf537-stamp.h | 1 + include/configs/bf609-ezkit.h | 1 - include/configs/gr_cpci_ax2000.h | 5 +- include/configs/gr_ep2s60.h | 5 +- include/configs/gr_xc3s_1500.h | 5 +- include/configs/grsim.h | 5 +- include/configs/grsim_leon2.h | 5 +- include/configs/openrisc-generic.h | 3 - include/configs/s32v234evb.h | 4 - include/configs/tegra-common.h | 2 +- include/configs/tegra114-common.h | 2 +- include/configs/tegra124-common.h | 2 +- include/configs/tegra186-common.h | 2 +- include/configs/tegra20-common.h | 2 +- include/configs/tegra210-common.h | 2 +- include/configs/tegra30-common.h | 2 +- lib/fdtdec.c | 31 +++--- scripts/config_whitelist.txt | 3 - 35 files changed, 360 insertions(+), 133 deletions(-) create mode 100644 arch/blackfin/dts/Makefile create mode 100644 arch/blackfin/dts/bf537-stamp.dts -- 2.8.0.rc3.226.g39d4020

[U-Boot] [PATCH 0/2] Series to clean handle_XXX() in f_dfu.c
by Patrick Delaunay 21 Feb '17

21 Feb '17

1/ DFU_GETSTATE response error when the DFU device state is requested using libusb with DFU_GETSTATUS a error is generated : LIBUSB_ERROR_IO I see the issue with my programmer tools based on dfu with libusb and I don't understood the actual code in U-Boot (req->actual is updated but not req->lenght ?) With the proposed patch, I aligned the code on the GETSTATUS behavior: the correct lenght is provided in req->lenght as the other answer and the issue is solved. PS: the issue not see with dfu-util as the existing function dfu_get_state() is never called in main (with dfu-util 0.9) But I can reproduce the same issue with patched version of dfu-util to add call to this function, on the dfu-util master branch diff --git a/src/main.c b/src/main.c index 7f31d4c..d99ace9 100644 --- a/src/main.c +++ b/src/main.c @@ -535,6 +535,13 @@ dfustate: } status_again: + printf("Determining device state: "); + ret = dfu_get_state(dfu_root->dev_handle, dfu_root->interface); + if (ret < 0) { + errx(EX_IOERR, "error get_state: %s", libusb_error_name(ret)); + } + printf("state = %s\n", dfu_state_to_string(ret)); + printf("Determining device status: "); ret = dfu_get_status(dfu_root, &status ); if (ret < 0) { 2/ harmonize handle_getstatus() with other function => add return value with size of the buffer as - handle_getstate() add in part 1 or existing functions - handle_dnload() - handle_upload() Patrick Delaunay (2): usb: gadget: dfu: correct size for USB_REQ_DFU_GETSTATE result usb: gadget: dfu: add result for handle_getstatus() drivers/usb/gadget/f_dfu.c | 56 ++++++++++++++++++++-------------------------- drivers/usb/gadget/f_dfu.h | 1 - 2 files changed, 24 insertions(+), 33 deletions(-) -- 1.9.1

[U-Boot] [PATCH v2 0/5] arm: imx6: tqma6: Kconfig rework
by Markus Niebel 19 Feb '17

19 Feb '17

From: Markus Niebel <Markus.Niebel(a)tq-group.com> This series extends the Kconfig options for TQMa6 to enable removal of CONFIG_SYS_EXTRA_OPTIONS for this boards. To enable env device / boot device configuration the first patch includes the Kconfig generated header in the board configuration header. To enable CPU selection the second patch moves the board selection to the i.MX6 CPU menu as implemented by the Seco mx6 boards Changed for v2: - rebase to current u-boot-imx - add new patch to fix envcrc build for non default boot / env devices - regenerate defconfigs to exclude defaults Markus Niebel (5): arm: imx6: tqma6: add kconfig to board header arm: mx6: tqma6: CPU type selection via Kconfig arm: imx6: tqma6: implement IMX_CONFIG with Kconfig arm: imx6: tqma6: boot device selection via Kconfig arm: imx6: tqma6: implement KConfig baseboard selection arch/arm/Kconfig | 5 ---- arch/arm/cpu/armv7/mx6/Kconfig | 5 ++++ board/tqc/tqma6/Kconfig | 58 +++++++++++++++++++++++++++++++++++++++ configs/tqma6q_mba6_mmc_defconfig | 2 +- configs/tqma6q_mba6_spi_defconfig | 3 +- configs/tqma6s_mba6_mmc_defconfig | 3 +- configs/tqma6s_mba6_spi_defconfig | 4 ++- include/configs/tqma6.h | 1 + 8 files changed, 72 insertions(+), 9 deletions(-) -- 2.3.0

[U-Boot] [PATCH 0/9] arm64: Unify MMU code
by Alexander Graf 16 Feb '17

16 Feb '17

Howdy, Currently on arm64 there is a big pile of mess when it comes to MMU support and page tables. Each board does its own little thing and the generic code is pretty dumb and nobody actually uses it. This patch set tries to clean that up. After this series is applied, all boards except for the FSL Layerscape ones are converted to the new generic page table logic and have icache+dcache enabled. The new code always uses 4k page size. It dynamically allocates 1G or 2M pages for ranges that fit. When a dcache attribute request comes in that requires a smaller granularity than our previous allocation could fulfill, pages get automatically split. I have tested and verified the code works on HiKey (bare metal), vexpress64 (Foundation Model) and zynqmp (QEMU). The TX1 target is untested, but given the simplicity of the maps I doubt it'll break. ThunderX in theory should also work, but I haven't tested it. I would be very happy if people with access to those system could give the patch set a try. With this we're a big step closer to a good base line for EFI payload support, since we can now just require that all boards always have dcache enabled. I would also be incredibly happy if some Freescale people could look at their MMU code and try to unify it into the now cleaned up generic code. I don't think we're far off here.
