* ubiformat: improve generation of UBI image sequenceSascha Hauer2019-07-151-1/+0
| | | | | | | | | | | | | | | | | | | | The UBI ec_hdr has an image_seq field. During attaching UBI expects that its value is the same for all eraseblocks. The value should be changed with every ubiformat and is used to detect half written images. In barebox we use a pseudo random number generated with rand() for this value. The ubiformat command calls srand(get_time_ns()) to initialize the pseudo random numbber generator. This is done in the option parser, so when ubiformat() is called directly (from fastboot for example) the pseudo random number generator is not initialized and we get the same values after every barebox restart. This patch moves the pseudo random number generator initialization to the place where the numbers are generated. Also use random32() rather than rand() to generate 32bit values rather than 15bit values (0 - RAND_MAX). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * commands: don't use stale errno when calling fb_openAhmad Fatoum2019-06-132-4/+6
| | | | | | | | | | | | | | | | | | | | | | fb_open returns a pointer and doesn't populate errno, which will result in a stale errno being evaluated by perror() on failure. Fix this by using strerror with the proper argument instead at call sites. While at it, correct the message prefix typo (s/fb_open/fb_open/).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for OP-TEE, see https://www.op-tee.org/ barebox starts in secure mode as usual. When booting a kernel the bootm code also loads the optee_os binary. Instead of jumping into the kernel barebox jumps into the optee_os binary and puts the kernel execution address into the lr register. OP-TEE then jumps into the kernel in nonsecure mode. The optee_os binary is passed with the -t option to bootm or with global.bootm.tee. Optionally OP-TEE can be compiled into barebox using the builtin firmware feature. Enable the Kconfig option and place or link your tee binary as optee.bin into the firmware directory. The amount of SDRAM which is kept free for OP-TEE is configurable. This patch was tested on a i.MX6 Nitrogen6x board.

This is the barebox adoption of the commit commit 8caab75fd2c2a92667cbb1cd315720bede3feaa9 Author: Geert Uytterhoeven <geert+renesas@glider.be> Date: Tue Jun 13 13:23:52 2017 +0200 spi: Generalize SPI "master" to "controller" Now struct spi_master is used for both SPI master and slave controllers, it makes sense to rename it to struct spi_controller, and replace "master" by "controller" where appropriate. For now this conversion is done for SPI core infrastructure only. Wrappers are provided for backwards compatibility, until all SPI drivers have been converted. Noteworthy details: - SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI master controllers, - spi_busnum_to_master() is retained, as it looks up masters only, - A new field spi_device.controller is added, but spi_device.master is retained for compatibility (both are always initialized by spi_alloc_device()), - spi_flash_read() is used by SPI masters only.
