[U-Boot] [RFC v2 00/11] efi_loader: rework bootefi/bootmgr
by AKASHI Takahiro 16 Apr '19

16 Apr '19

There are several reasons that I want to rework/refactor bootefi command as well as bootmgr: * Some previous commits on bootefi.c have made the code complicated and a bit hard to understand. * do_bootefi_exec() would better be implemented using load_image() along with start_image() to be aligned with UEFI interfaces. * Contrary to the other part, efi_selftest part of the code is unusal in terms of loading/execution path in do_bootefi(). * When we will support "secure boot" in the future, EFI Boot Manager is expected to be invoked as a standalone command without any arguments to mitigate security surfaces. In this patch set, Patch#1 is a bug fix. Patch#2 to #9 are preparatory patches for patch#10. Patch#10 is a core part of reworking. Patch#11 is for standalone boot manager. # Please note that some patches, say patch#4 and #5, can be combined into one # but I intentionally keep them separated to clearify my intentions of changes. Prerequsite patch: * "efi_loader: bootmgr: support BootNext and BootCurrent variable behavior" * "efi_loader: release file buffer after loading image" Issues: * load_image() will take an argument of "parent_handle," but obviously we don't have any parent when invoking an application from command line. (See FIXME in patch#10.) * Starting EDK2's Shell.efi from boot manager fails. (I need to find out a fix.) * The semantics of efi_dp_from_name() should be changed. (See FIXME in patch#10.) -Takahiro Akashi Changes in RFC v2 (Mar 27, 2019) * rebased on v2019.04-rc4 * use load_image API in do_bootmgr_load() * merge efi_install_fdt() and efi_process_fdt() * add EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL to image (patch#1) * lots of minor changes AKASHI Takahiro (11): efi_loader: boottime: add loaded image device path protocol to image handle efi_loader: boottime: export efi_[un]load_image() efi_loader: device_path: handle special case of loading cmd: bootefi: carve out fdt handling from do_bootefi() cmd: bootefi: merge efi_install_fdt() and efi_process_fdt() cmd: bootefi: carve out efi_selftest code from do_bootefi() cmd: bootefi: move do_bootefi_bootmgr_exec() forward cmd: bootefi: carve out bootmgr code from do_bootefi() cmd: bootefi: carve out do_boot_efi() from do_bootefi() efi_loader: rework bootmgr/bootefi using load_image API cmd: add efibootmgr command cmd/Kconfig | 8 + cmd/bootefi.c | 521 +++++++++++++++++++----------- include/efi_api.h | 4 + include/efi_loader.h | 15 +- lib/efi_loader/efi_bootmgr.c | 43 +-- lib/efi_loader/efi_boottime.c | 34 +- lib/efi_loader/efi_device_path.c | 8 + lib/efi_loader/efi_image_loader.c | 2 + 8 files changed, 411 insertions(+), 224 deletions(-) -- 2.20.1

[U-Boot] [PATCH] mmc: support hs400 enhanced strobe mode
by Peng Fan 16 Apr '19

eMMC 5.1+ supports HS400 Enhances Strobe mode without the need for tuning procedure. The flow is as following: - set HS_TIMIMG (Highspeed) - Host change freq to <= 52Mhz - set the bus width to Enhanced strobe and DDR8Bit(CMD6), EXT_CSD[183] = 0x86 instead of 0x80 - set HS_TIMING to 0x3 (HS400) - Host change freq to <= 200Mhz - Host select HS400 enhanced strobe complete Signed-off-by: Peng Fan <peng.fan(a)nxp.com> --- This is actually a resend of https://patchwork.ozlabs.org/patch/1018188/ which got no response.

[U-Boot] [PATCH v5 00/27] ARM: tegra: Miscalleneous improvements
by Thierry Reding 15 Apr '19

15 Apr '19

From: Thierry Reding <treding(a)nvidia.com> Hi Tom, Stephen, this in the fifth installment of this series of miscellaneous improvements for Tegra support. The main changes since the last version are: - Add two patches from the "framebuffer carveout" series since Simon has already picked up the libfdt and fdtdec specific parts. - Fix the MAC address regression found by Stephen's test system. This is done by writing the MAC address to U-Boot's control DTB rather than storing it in the environment and thereby confusing Ethernet drivers if more than one device are present in the system. - I've also added the Jetson Nano patch to the series since it has changed slightly. The issue of the pinmux spreadsheet is still open, so this isn't quite ready to be merged, but I wanted to solicit more feedback, so that this is already reviewed by the time the pinmux spreadsheet issue is resolved. Simon, I've included another patch for a new fdtdec function in this series because the first user is introduced here. It'd be great if you could provide an Acked-by on the first patch so that Tom can pick it up and send out as part of the PR for the entire series once it's been reviewed and passed Stephen's test system. The second patch is also required later in the series. There's no explicit maintainer for lib/string.c, but you show up in the output for scripts/get_maintainer.pl for the second patch, so perhaps you could also give an Acked-by on that? Alternatively you could pick up patches 1 and 2 so that Tom can base his PR on your tree (or master, later on), if that's what you guys prefer. Actually, this might be better anyway, since there might be a tiny merge conflict between the fdtdec patch in this series and the other ones that I sent out earlier.

[U-Boot] [REQ] ls command with date and filename-only
by Frank Wunderlich 15 Apr '19

15 Apr '19

Hi, is it possible to extend ls-command (file-listing) with the filedate (modification-date) and with option to show only the filename? i looked around a bit and fs_dirent (include/fs.h) needs to be extended with a field for holding the timestamp. how should it be stored (uint32 for unix-timestamp)? how can i print this as datetime in fs_ls_generic (fs/fs.c)? how to add extra optional param to ls-command (without breaking current behaviour)? ls is defined in cmd/fs.c with 3 params (driver, partition, directory). how to define optional params? imho i need to increase the current value (4=>5), check the paramcount in do_ls (fs/fs.c) and if it's 5 use the 4th as option (currently >4 exits the command, partition seems optional atm...this brings me problems)...also the directory is optional (index 3/null) regards Frank

[U-Boot] [PATCH] crypto: fsl: jr: Make job-rings assignment non-Secure dependent
by Breno Matheus Lima 15 Apr '19

15 Apr '19

Commit 22191ac35344 ("drivers/crypto/fsl: assign job-rings to non-TrustZone") breaks HABv4 encrypted boot support in the following i.MX devices: - i.MX6UL - i.MX7S - i.MX7D - i.MX7ULP For preparing a HABv4 encrypted boot image it's necessary to encapsulate the generated DEK in a blob. In devices listed above the blob generation function takes into consideration the Job Ring TrustZone ownership configuration (JROWN_NS) and can be only decapsulated by the same configuration. The ROM code expects DEK blobs encapsulated by the Secure World environments which commonly have JROWN_NS = 0. As U-Boot is running in Secure World we must have JROWN_NS = 0 so the blobs generated by dek_blob tool can be decapsulated by the ROM code. Linux Kernel is booting by default in TrustZone Secure World in most of targets. Make job-rings assignment to non-Secure dependent of CONFIG_OPTEE and CONFIG_ARMV7_BOOT_SEC_DEFAULT to avoid a Kernel crash when booting Linux in non-Secure World. OP-TEE users can still use dek_blob command as job ring assignment is also dependent of CONFIG_CMD_DEKBLOB configuration.
