[U-Boot] [PATCH v11 0/3] Why netboot:
by DH＠synoia.com 12 Jun '18

12 Jun '18

From: Duncan Hare <DuncanCHare(a)yahoo.com> Central management, including logs and change control, coupled with with enhanced security and unauthorized change detection and remediation by exposing a small attack surface. Why TCP with Selective Acknowledgement: Currently file transfer are done using tftp or NFS both over udp. This requires a request to be sent from client (u-boot) to the boot server. For a 4 Mbyte kernel, with a 1k block size this requires 4,000 request for a block. Using a large block size, one greater than the Ethernet maximum frame size limitation, would require fragmentation, which u-boot supports. However missing fragment recovery requires timeout detection and re-transmission requests for missing fragments. UDP is ideally suited to fast single packet exchanges, inquiry/response, for example dns, becuse of the lack of connection overhead. UDP as a file transport mechanism is slow, even in low latency networks, because file transfer with udp requires poll/response mechanism to provide transfer integrity. In networks with large latency, for example: the internet, UDP is even slower. What is a 30 second transfer on a local boot server and LAN increase to over 3 minutes, because of all the requests/response traffic. This was anticipated in the evolution of the IP protocols and TCP was developed and then enhanced for high latency high bandwidth networks. The current standard is TCP with selective acknowledgment. In our testing we have reduce kernel transmission time to around 0.4 seconds for a 4Mbyte kernel, with a 100 Mbps downlink. Why http and wget: HTTP is the most efficient file retrieval protocol in common use. The client send a single request, after TCP connection, to receive a file of any length. WGET is the application which implements http file transfer outside browsers as a file transfer protocol. Versions of wget exists on many operating systems.

[U-Boot] [PATCH v3 0/3] drivers: Add reset ctrl to drivers
by Ley Foon Tan 12 Jun '18

12 Jun '18

Add reset ctrl to dwmmc socfpga, designware Ethernet and ns16550 serial drivers. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset. This is preparation to upstream Intel Stratix 10 SoC support in [1]. v2 change: - remove #ifdef CONFIG_DM_RESET switch - add maintainer emails History: v1: https://patchwork.ozlabs.org/cover/905519/ v2: https://patchwork.ozlabs.org/cover/908667/ [1]: https://patchwork.ozlabs.org/cover/900499/ Ley Foon Tan (3): mmc: dwmmc: socfpga: Add reset ctrl to driver serial: ns16550: Add reset ctrl to driver net: designware: Add reset ctrl to driver drivers/mmc/socfpga_dw_mmc.c | 17 +++++++++++++++++ drivers/net/designware.c | 8 ++++++++ drivers/serial/ns16550.c | 8 ++++++++ 3 files changed, 33 insertions(+), 0 deletions(-)

[U-Boot] [PATCH v8 00/18] Add fastboot UDP support
by Alex Kiernan 12 Jun '18

12 Jun '18

This series merges the fastboot UDP support from AOSP into mainline U-Boot. Changes in UDP behaviour from the AOSP code, so it follows the existing USB behaviour: - 'boot' now follows the USB code and does 'bootm CONFIG_FASTBOOT_BUF_ADDR'. I've added 'fastboot_bootcmd' which if set overrides the boot command and allows the existing UDP behaviour to be preserved. - 'continue' in UDP now exits the fastboot server rather than executing 'run bootcmd' - 'reboot-bootloader' no longer writes 'reboot-bootloader' to CONFIG_FASTBOOT_BUF_ADDR as its marker for the subsequent boot. The code which is in AOSP common/android_bootloader.c expects this marker, but we have prior art in the USB code using the weak function fastboot_set_reboot_flag - 'getvar' in the UDP path now supports fetching 'fastboot.' prefixed variables (inherited from the USB path), these override the defaults I've pushed both USB and UDP into a single consolidated protocol layer now I've tested it on a BeagleBone Green. Green Travis build: https://travis-ci.org/akiernan/u-boot/builds/383077278 Changes in v8: - add Reviewed-by: tag - add Reviewed-by: tag - add Reviewed-by: tag Changes in v7: - set FASTBOOT_CMD_OEM_FORMAT for all existing users of FASTBOOT_FLASH_MMC_DEV that also have CMD_GPT Changes in v6: - accomodate master change and switch dependency on imx6dl_mamoj from FASTBOOT to USB_FUNCTION_FASTBOOT - delete redundant FASTBOOT_FLASH_NAND_DEV symbol - add docbook comments - add docbook comments - rename fastboot_download_data() to fastboot_data_download(), rename fastboot_get_bytes_remaining() to fastboot_data_remaining() - split fastboot_data_complete() out from fastboot_data_download() so we can call it at the end of the transfer phase for USB - merged from RFC USB fastboot series - when entering the DATA phase ensure we actually install the correct handler - on completion of DATA call new fastboot_data_complete() - previous changes: - remove redundant version.h - use new fastboot_get_bytes_remaining() function - new Changes in v5: - don't depend on UDP_FUNCTION_FASTBOOT until it exists - squash in subsequent patch which updates defconfigs so we don't leave users of CONFIG_FASTBOOT without it enabled - fix build in drivers/fastboot when we have CONFIG_FASTBOOT without flash or erase and we've not yet added fb_common.c to the build - fix docbook formatting - new - new - rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE and migrate it to Kconfig. - make fastboot_bytes_received/expected static and add function fastboot_get_bytes_remaining() - move fastboot_buf_addr/fastboot_buf_size/fastboot_progress_callback into fastboot-internal.h - delete redundant fb_ prefixes from statics - new Changes in v4: - add docbook comments - leave strcmp_l1() in USB fastboot as we don't need it in UDP path - add docbook comments - new - guard fb_getvar/fb_command with UDP_FUNCTION_FASTBOOT in Makefile - add docbook comments - remove parameter from fastboot_boot() since we always want fastboot_buf_addr (and if we're using fastboot_bootcmd then it's ignored) - split oem format into new patch Changes in v3: - move imply ANDROID_BOOT_IMAGE, CMD_FASTBOOT to FASTBOOT from USB_FUNCTION_FASTBOOT - add depend on USB_FUNCTION_FASTBOOT to FASTBOOT_USB_DEV - leave images-sparse.c in common to acommodate 2f83f21 - refactor for changes in master - Merge subsequent patch for formatting response strings into this one - allow NULL to fastboot_okay() when there's no message to send - guard FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME with EFI/DOS_PARTITION - new - new - new - new - new - new - use FASTBOOT as our guard in Kconfig not a list of USB || UDP - correct mis-translation from AOSP introduced when cleaning up for checkpatch - we should write when buffer is not NULL, rather than erasing, and erase when buffer is NULL - use CMD_RET_USAGE from do_fastboot - remove do_fastboot_udp from cmd/net.c and rewrite using net_loop() - rename timed_send_info to fastboot_send_info, rename fastboot_send_info to fastboot_udp_send_info - replace FASTBOOT_HEADER_SIZE with sizeof(struct fastboot_header) - move start time into timed_send_info() rather than passing it in - make calls to fastboot_udp_send_info a runtime dependency, not a compile time one - set ${filesize} to size of downloaded image - add progress meter from USB path during download - add support for 'oem format' command from the USB path - rename 'fastbootcmd' to 'fastboot_bootcmd' to make clear that this is the fastboot boot command - make getvar implementation table driven - add fastboot_buf_addr, fastboot_buf_size to override buffer address and size - return correct filesystem type in getvar partition-type on MMC - process "fastboot." prefixed env variables in getvar first so you can override the normal values (this also lets you set a fs type for NAND devices) - squash subsequent patches which change this code into this one: - If the fastboot flash/erase commands are disabled, remove that support so we still build correctly. - Add NAND support to fastboot UDP flash/erase commands - If we don't have a partition name passed, report it as not found. - Change the behaviour of the fastboot net code such that "reboot-bootloader" is no longer written to CONFIG_FASTBOOT_BUF_ADDR for use as a marker on reboot (the AOSP code in common/android-bootloader.c uses this marker - this code could be reinstated there if that gets merged). - Merge USB and UDP boot code. The USB implementation stays the same, but UDP no longer passes an fdt. We introduce a new environment variable 'fastboot_bootcmd' which if set overrides the hardcoded boot command, setting this then allows the UDP implementation to remain the same. If after running 'fastboot_bootcmd' the board has not booted, control is returned to U-Boot and the fastboot process ends. - Separate the fastboot protocol handling from the fastboot UDP code in preparation for reusing it in the USB code.

[U-Boot] [RFC] efi_loader: support for CONFIG_ARMV7_NONSEC
by Heinrich Schuchardt 12 Jun '18

12 Jun '18

Booting with SMP fails on the Allwinner A20 CPU. https://gist.github.com/xypron/2524ba898d6905d959c744c2b05da196 When executing bootefi we need to * copy the Power State Coordination Interface (PSCI) code to its destination address * switch between our hypervisor mode (HYP) and the supervisor mode (SVC) of the payload (http://linux-sunxi.org/PSCI) This patch is incomplete. It is just meant to indicate where we could change the entry point. With the patch iPXE cannot get a network address. Possibly a better moment for switching to SVC is ExitBootServices. We also have to consider switching modes at EFI_ENTRY and EFI_EXIT.

[U-Boot] [PATCH v3] x86: use EFI calling convention for efi_main on x86_64
by Ivan Gorinov 12 Jun '18

12 Jun '18

UEFI specifies the calling convention used in Microsoft compilers; first arguments of a function are passed in (%rcx, %rdx, %r8, %r9). All other compilers use System V ABI by default, passing first integer arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9). These ABI also specify different sets of registers that must be preserved across function calls (callee-saved). GCC allows using the Microsoft calling convention by adding the ms_abi attribute to a function declaration. Current EFI implementation in U-Boot specifies EFIAPI for efi_main() in the test apps but uses default calling convention in lib/efi. The arguments of efi_main() are also passed as unused arguments to the _relocate() function. Save efi_main() arguments in the startup code on x86_64; use EFI calling convention for _relocate() on x86_64; remove unused _relocate() arguments; consistently use EFI calling convention for efi_main() everywhere. v3: Updated patch description. v2: Added EFIABI to _relocate() declaration.

[U-Boot] [PATCH v2 0/7] Improvements for the dwc3_generic driver
by Jean-Jacques Hiblot 12 Jun '18

12 Jun '18

This series aims at bringing improvements to the dwc3_generic driver so that it can be used by most of the platforms using the dwc3 controller. This series applies on top of the master branch of USB tree. It also also available on github: https://github.com/jjhiblot/u-boot/tree/dwc3_generic_v2 I tested this on with DRA7 and AM57x platforms for both Peripheral and Host operations. The code to enable DM USB host & dev support for those platforms will be submitted in a separate series. Enhancements: - use separate Kconfig option for DM USB Periphal and DM USB Host. This allow platforms to keep their non-DM USB peripheral code and use the DM USB host. - fixes the bind/probe confusion in dwc3_generic. The probe is done when the USB device is first needed. - handles PHYs when in the peripheral mode. The code to handle the PHYs is shared with the host side - handles clock and reset - bind host controller to the more generic driver 'xhci-dwc3' Changes in v2: - Updated commit log - Fixed typo in thordown.c - select DM_USB_DEV by default for zynqmp platforms Jean-Jacques Hiblot (7): usb: gadget: Do not call board_usb_xxx() directly in USB gadget drivers usb: introduce a separate config option for DM USB device usb: udc: implement DM versions of usb_gadget_initialize()/_release()/_handle_interrupt() dwc3_generic: do not probe the USB device driver when it's bound dwc3: move phy operation to core.c dwc3-generic: Handle the PHYs, the clocks and the reset lines dwc3-generic: Add select_dr_mode operation arch/arm/Kconfig | 2 + cmd/fastboot.c | 4 +- cmd/rockusb.c | 4 +- cmd/thordown.c | 4 +- cmd/usb_gadget_sdp.c | 4 +- cmd/usb_mass_storage.c | 4 +- common/dfu.c | 6 +- drivers/usb/Kconfig | 6 ++ drivers/usb/dwc3/Kconfig | 7 +- drivers/usb/dwc3/core.c | 86 +++++++++++++++- drivers/usb/dwc3/dwc3-generic.c | 207 +++++++++++++++++++++++++++++--------- drivers/usb/dwc3/ep0.c | 1 - drivers/usb/gadget/ether.c | 38 +------ drivers/usb/gadget/udc/udc-core.c | 44 +++++++- drivers/usb/host/xhci-dwc3.c | 93 ++--------------- include/dwc3-uboot.h | 7 ++ include/linux/usb/gadget.h | 18 ++++ 17 files changed, 351 insertions(+), 184 deletions(-) -- 2.7.4
