| | | | | | | | | The 'bootz' command is really only for ARM32 Linux Kernel 'zImage' files but has also been adapted for testing with sandbox.

| | | | | | | | | | | | The bootz and booti commands rely on common functionality that is found in common/bootm.c and common/bootm_os.c. They do not however rely on the rest of cmd/bootm.c to be implemented so split them into their own files. Have various Makefiles include the required infrastructure for CONFIG_CMD_BOOT[IZ] as well as CONFIG_CMD_BOOTM. Move the declaration of 'images' over to common/bootm.c.

| | | | | | | | | | | | This adds a bunch of unit tests for the "fdt apply" command. They've all been run successfully in the sandbox. However, as you still require an out-of-tree dtc with overlay support, this is disabled by default.

* cmd: fdt: add fdt overlay application subcommandMaxime Ripard2016-08-20-7/+31
| | | | | | | | | | | | | | | | | | | | | | | The device tree overlays are a good way to deal with user-modifyable boards or boards with some kind of an expansion mechanism where we can easily plug new board in (like the BBB or the raspberry pi). However, so far, the usual mechanism to deal with it was to have in Linux some driver detecting the expansion boards plugged in and then request these overlays using the firmware interface. That works in most cases, but in some cases, you might want to have the overlays applied before the userspace comes in. Either because the new board requires some kind of an early initialization, or because your root filesystem is accessed through that expansion board. The easiest solution in such a case is to simply have the component before Linux applying that overlay, removing all these drawbacks.

| | | | | | | | | | | | | | | | | | | | | | | | | 56086921 added support for unaligned environments access. U-boot itself does not support this: - env_nand.c fails when using an unaligned offset. It produces an error in nand_erase_opts{drivers/mtd/nand/nand_util.c} - in env_sf/env_flash the unused space at the end is preserved, but not in the beginning. block alignment is assumed - env_sata/env_mmc aligns offset/length to the block size of the underlying device. data is silently redirected to the beginning of a block There is seems no use case for unaligned environment. If there is some useful data at the beginning of the the block (e.g. end of u-boot) that would be very unsafe. If the redundant environments are hosted by the same erase block then that invalidates the idea of double buffering. It might be that unaligned access was allowed in the past, and that people with legacy u-boot are trapped. But at the time of 56086921 it wasn't supported and due to reasons above I guess it was never introduced.
