menu: remove CTRL+C to quit

2023-02-10T12:05:39Z

On the sandbox called without "--terminal raw" CTRL+C leaves U-Boot, "ESC/CTRL+C to quit" is misleading. Let's remove CTRL+C to quit key handling from bootmenu and eficonfig menu. Signed-off-by: Masahisa Kojima Reviewed-by: Heinrich Schuchardt

cmd: Add a SEAMA image load command

2023-02-06T22:10:15Z

Add a command to load SEAMA (Seattle Image), a NAND flash on-flash storage format. This type of flash image is found in some D-Link routers such as DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and DCH-M225, as well as in WD and NEC routers on the ath79 (MIPS), Broadcom BCM53xx, and RAMIPS platforms. This U-Boot command will read and decode a SEAMA image from raw NAND flash on any platform. As it is always using big endian format for the data decoding is always necessary on platforms such as ARM. The command is needed to read a SEAMA-encoded boot image on the D-Link DIR-890L router for boot from NAND flash in an upcoming port of U-Boot to the Broadcom Northstar (BCM4709, BCM53xx) architecture. A basic test and documentation is added as well. The test must be run on a target with NAND flash support and at least one resident SEAMA image in flash.

bootstd: Add some default filesystems and commands

2023-02-06T18:04:53Z

We need to support a basic set of filesystems for booting to work in most cases. Add these in via a new option, letting the board disable them individually (for space reasons) if desired. This enables the filesystem commands as well as the actual functionality, even though bootstd is quite happy to use ext4 without the ext4 command. Further work would be needed to disintangle this and reduce code size. Add several other options as well, providing sensible defaults. We cannot enable this by default, since it expands the size of many boards quite a lot. Signed-off-by: Simon Glass
