Re: [PATCH 05/18] treewide: bootm: Drop command-line args to boot_os_fn

Hi Simon,

Acked-by: Angelo Dureghello angelo@kernel-space.org

On 04/12/23 1:26 AM, Simon Glass wrote:

These arguments are not used now. They cannot be provided when there is no bootm command invoked to provide arguments. Drop the argc and argv parameters.
