by Akash Gajjar 05 Nov '18

05 Nov '18

From: Akash Gajjar <gajjar04akash(a)gmail.com> This patch adds support for DM to the LPC32xx SSP SPI driver. Some TODOs are left over for later, These would be enhancements to the original functionality, and can come later. The legacy functionality is removed in this version.

[U-Boot] [PATCH] sunxi: lower the DDR frequency of Orange Pi Prime
by Icenowy Zheng 29 Oct '18

29 Oct '18

When I use Orange Pi Prime to do some heavy compliation tasks, the gcc compiler sometimes mysteriously segfaults, and memtester catches memory error. As the lima-memtester cannot support H5 (Mali-450 GPU equipped), there's no really reliable way to detect DRAM stability except try and error. Lower the DDR frequency to 624MHz seems to solved the issue. Set the default frequency to 624MHz in the defconfig, as 672MHz is observed to be unstable at least on my board.

[U-Boot] [RFC PATCH 0/3] sunxi: extend SPL header to propagate DRAM size
by Andre Przywara 22 Oct '18

22 Oct '18

This series tries to solve three issues we currently have on Allwinner boards: - The DRAM sizing routine can only cope with power-of-two sized DRAM. - The DRAM sizing routine steps through all DRAM, possibly hitting secure memory. - The SPL header versioning is quite strict and tends to break every time we need to update it. So I thought about introducing something along the lines of semantic versioning[1], where we can add backwards-compatible changes to the SPL header without breaking every tool. This is introduced in the first patch. The second patch does some refactoring, so that the third patch can use the newly gained freedom to store the DRAM size. The SPL knows the DRAM size very well, so we store this in the SPL header, so that U-Boot proper can pick it up from there. This saves the call to get_ram_size() with its deficiencies. More information in the respective commit messages. I understand that this versioning solution is not fully future-proof, but we have only one byte for the version, and I just wanted to start discussion on this. There is a corresponding patch for sunxi-tools as well I am posting shortly. [1] https://semver.org Cheers, Andre.

[U-Boot] [PATCH 00/41] imx: add i.MX8QXP support
by Peng Fan 18 Oct '18

18 Oct '18

This patchset is to upstream i.MX8QXP and mek board support, with some drivers update to support i.MX8QXP. The information about the processor could be found https://www.nxp.com/products/processors-and-microcontrollers/applications-p… The architecture of i.MX8QXP is different from i.MX6/7/8M, inside i.MX8QXP, there is a dedicated processor(SCU) used for power/clock/pin/ pad/resource management/thermal and etc. The ACore need to communicate with SCU using SCFW API. The SCFW API is exported by SCFW, so we directly import it into U-Boot source code. Gao Pan (1): imx: lpi2c: fix clock issue when NACK detected Peng Fan (32): imx: import SCFW API imx: add Kconfig entry for i.MX8 arm: build mach-imx for i.MX8 imx8: add IPC communication support

[U-Boot] [PATCH v5 00/13] efi: Enable basic sandbox support for EFI loader
by Simon Glass 15 Oct '18

15 Oct '18

A limitation of the EFI loader at present is that it does not build with sandbox. This makes it hard to write tests, since sandbox is used for most testing in U-Boot. This series enables the EFI loader feature. It allows sandbox to build and run a trivial function which calls the EFI API to output a message. This series is at u-boot-dm/efi-working Changes in v5: - Add new patch to disallow CMD_BOOTEFI_SELFTEST on sandbox - Drop call to efi_init_obj_list() which is now done in do_bootefi() - Drop period after "elf" in comment - Introduce load_options_path to specifyc U-Boot env var for load_options_path - Rebase to master Changes in v4: - Move the fix to query_console_serial() - Rebase to master - Update SPDX tags Changes in v3: - Add new patch to init the 'rows' and 'cols' variables - Add new patch to rename bootefi_test_finish() to bootefi_run_finish() - Add new patch to split out test init/uninit into functions - Add patch to create a function to set up for running EFI code - Drop incorrect map_sysmem() in write_smbios_table() - Init the 'rows' and 'cols' vars to avoid a compiler error (gcc 4.8.4) - Rebase to master Changes in v2: - Rebase to master - Update to use mapmem instead of a cast Simon Glass (13): efi: Don't allow CMD_BOOTEFI_SELFTEST on sandbox efi: Init the 'rows' and 'cols' variables efi: sandbox: Adjust memory usage for sandbox sandbox: smbios: Update to support sandbox efi: sandbox: Add distroboot support efi: sandbox: Add relocation constants efi: Add a comment about duplicated ELF constants efi: sandbox: Enable EFI loader builder for sandbox efi: Split out test init/uninit into functions efi: sandbox: Add a simple 'bootefi test' command efi: Create a function to set up for running EFI code efi: Rename bootefi_test_finish() to bootefi_run_finish() buildman: Add a --boards option to specify particular boards to build cmd/bootefi.c | 153 ++++++++++++++++++++++---------- include/config_distro_bootcmd.h | 2 +- include/efi_loader.h | 3 + lib/efi_loader/Kconfig | 12 ++- lib/efi_loader/Makefile | 1 + lib/efi_loader/efi_console.c | 5 +- lib/efi_loader/efi_memory.c | 31 ++++--- lib/efi_loader/efi_runtime.c | 7 ++ lib/efi_loader/efi_test.c | 16 ++++ lib/efi_selftest/Kconfig | 2 +- lib/smbios.c | 32 +++++-- tools/buildman/README | 12 ++- tools/buildman/board.py | 28 +++++- tools/buildman/cmdline.py | 4 +- tools/buildman/control.py | 20 ++++- tools/buildman/test.py | 31 ++++--- 16 files changed, 264 insertions(+), 95 deletions(-) create mode 100644 lib/efi_loader/efi_test.c -- 2.18.0.rc1.244.gcf134e6275-goog

[U-Boot] [BUG] snow: mmc: SD card access broken: unable to select a mode
by Guillaume Gardet 15 Oct '18

15 Oct '18

Hi Jaehoon, There are problems with SD card access on Samsung Chromebook (snow) with latest master (and also 2018.05-rc1 and 2018.03). eMMC is ok, but SD card access leads to 'unable to select a mode' problem. If I disable HS mode, I can access the SD card without problem: ******************************************************************************** diff --git a/drivers/mmc/dw_mmc.c b/drivers/mmc/dw_mmc.c index 23f642980bf..28f4fa0f213 100644 --- a/drivers/mmc/dw_mmc.c +++ b/drivers/mmc/dw_mmc.c @@ -508,7 +508,8 @@ void dwmci_setup_cfg(struct mmc_config *cfg, struct dwmci_host *host, cfg->host_caps |= MMC_MODE_4BIT; cfg->host_caps &= ~MMC_MODE_8BIT; } - cfg->host_caps |= MMC_MODE_HS | MMC_MODE_HS_52MHz; + /* Temp workaround for Chromebook snow to avoid the 'unable to select a mode' error */ +// cfg->host_caps |= MMC_MODE_HS | MMC_MODE_HS_52MHz; cfg->b_max = CONFIG_SYS_MMC_MAX_BLK_COUNT; } ******************************************************************************** Once we try to select HS mode, all access to SD card result in failure, even when trying to setup a lower frequency mode, including SD legacy at 25 MHz.

11 Oct '18

From: Duncan Hare <DH(a)Synoia.com> To make it possible to add TCP versions of the same, while reusing IP portions. This patch should not change any behavior. All references to TCP removed Used most recent version of u-boot June 22 13, 2918 Series to fix patman errors over Licensing declaration END Series-notes TCP with Selective Acknowledgment (SACK) is currently the protocol with highest speed transfers, for fast multi-hop networks.

[U-Boot] [PATCH] rtc: Add read8 and write8 support to isl1208 driver
by Trent Piepho 11 Oct '18

This can be used for device register access from board code. This allows access to capabilities in the RTC chip not abstracted in U-Boot's RTC class. E.g., device NVRAM or a tamper detection circuit.

[U-Boot] [PATCH 00/11] efi_loader: patches for Shell.efi
by Rob Clark 10 Oct '18

10 Oct '18

Re-send of the patch series to get Shell.efi working, and almost get SCT.efi (the UEFI test suite) working. Since last time, I've updated to Heinrich's latest SetWatchdogTimer patch (as of yesterday evening), and adressed review comments on the three new sets of protocols added. Part of that, to avoid moving changes from my later patch that added implementation on top of Leif's initial stubs was done by simply squashing the patches together.

u-boot.itb depends on u-boot-nodtb.bin, which in turn depends on u-boot. u-boot.its from Rockchip make_fit_atf.py (used by {evb,firefly}-rk3399) wants to read u-boot but is lacking this dependency, so that u-boot.itb cannot be built in one go.
