2021-01-31	cmd: bcb: Add support for processing const string literals in bcb_set()	Eugeniu Rosca	1	-2/+2
	On request/suggestion from Simon Glass back in May 22 2019 [1], the 'strsep' mechanism implemented in bcb_set() was set to work directly with user-provided argv strings, to avoid duplicating memory and for the sake of simpler implementation. However, since we recently exposed bcb_write_reboot_reason() API to be called by U-Boot fastboot, the idea is to be able to pass const string literals to this new BCB API, carrying the reboot reason. Since 'strsep' (just like its older/superseded sibling 'strtok') modifies the input string passed as parameter, BCB command in its current state would attempt to perform in-place modifications in a readonly string, which might lead to unexpected results. Fix the above with the cost of one dynamic memory allocation ('strdup'). This will also ensure no compiler warnings when passing string literals to bcb_write_reboot_reason().

2021-01-31	cmd: bcb: Expose 'bcb_write_reboot_reason' to external callers	Eugeniu Rosca	1	-0/+21
	Fastboot is evolving and beginning with commit [1], the upstream implementation expects bootloaders to offer support for: - reboot-recovery - reboot-fastboot The most natural way to achieve the above is through a set of pre-defined "reboot reason" strings, written into / read from the BCB "command" field, e.g.: - bootonce-bootloader [2] - boot-fastboot [3] - boot-recovery [4] Expose the first 'bcb' API meant to be called by e.g. fastboot stack, to allow updating the BCB reboot reason via the BCB 'command' field.
