[U-Boot] [PATCH v2 0/8] Convert i.MX7 WaRP7 ports to DM
by Bryan O'Donoghue 09 Jan '19

09 Jan '19

V2: - Add review-by as indicated - Peng Fan - Squash commit 4 and 5 from v1 - Peng Fan - Leave usdhc1 intact because of alias of mmc0 to usdhc3 - Bryan - Add correction for spelling mistake in imx7d-pinfunc.h - Lukas Auer - Imports imx7s-warp7.dts from kernel unmodified as a result of #1 - Bryan V1: This series does a minimal conversion of WaRP7 and the BL33 version of WaRP7 to the DM. Pinctrl, GPIO, I2C, Regulators, PMIC and MMC are converted. Later patches will convert USB and UART.

[U-Boot] [PATCH 0/5] efi_loader: rework loading and starting of images
by Heinrich Schuchardt 09 Jan '19

09 Jan '19

This patch series starts the necessary changes needed to correctly implement the unloading of images in Exit(). If we want to properly unload images in Exit() the memory should always be allocated in the same way. As we allocate memory when reading from file we should do the same when the original image is in memory. Up to now efi_load_pe() returns the entry point or NULL in case of an error. This does not allow to return correct error codes from LoadImage(). Let efi_load_pe() return a status code and fill in the entry point in the corresponding field of the image object. We use u16* for Unicode strings and efi_uintn_t for UINTN. Correct the signature of efi_exit() and efi_start_image(). Remove the duplicate code in efi_do_enter() and use efi_start_image() to start the image invoked by the bootefi command. Adjust a debug message. Further patches will be needed: - use LoadImage() in bootefi and bootmgr - implement correct unloading of images in Exit() Heinrich Schuchardt (5): efi_loader: LoadImage: always allocate new pages efi_loader: set entry point in efi_load_pe() efi_loader: avoid unnecessary pointer to long conversion efi_loader: signature of StartImage and Exit efi_loader: use efi_start_image() for bootefi cmd/bootefi.c | 33 ++------------ include/efi_api.h | 6 +-- include/efi_loader.h | 10 +++-- lib/efi_loader/efi_bootmgr.c | 2 +- lib/efi_loader/efi_boottime.c | 74 +++++++++++++++++++------------ lib/efi_loader/efi_image_loader.c | 34 ++++++++------ 6 files changed, 81 insertions(+), 78 deletions(-) -- 2.19.2

[U-Boot] common/board_f.c: init_sequence_f_r used for which arches?
by Robert P. J. Day 08 Jan '19

just noticed in common/board_f.c the inconsistency: #if defined(CONFIG_X86) || defined(CONFIG_ARC) /* * For now this code is only used on x86. ... snip ... * NOTE: At present only x86 uses this route, but it is intended that * all archs will move to this when generic relocation is implemented. */ so should the comment be changed to refer to both x86 and arc, or is there a long-term plan for all archs, or what? rday -- ======================================================================== Robert P.
