Until now, ubldr has been trying to locate the U-Boot API using a hint address (U-Boot's current stack pointer), aligning it to 1MiB and going over a 3MiB (or 1MiB in case of MIPS) memory region searching for a valid API signature. This change introduces an alternative way of doing this, namely the following: - both U-Boot's bootelf and go commands actually pass argc and argv to the entry point (e.g., ubldr's start function, but they should also be passed over to main() transparently) - so, instead of trying to go and look for a valid API signature, we look at the parameters passed to main() - if there's an option '-a' with argument, which is a valid hexadecimal unsigned long number (x), we try to verify whether we have a valid API signature at address x. If so - we use it. If not - we fallback to the original way of locating the API signature. The U-Boot change, which causes the API structure address to be exported as an environment variable, was committed to mainline U-Boot as commit 22aa61f707574dd569296f521fcfc46a05f51c48 Reviewed by: andrew, adrian Approved by: adrian (mentor) Sponsored by: Smartcom - Bulgaria AD Differential Revision: https://reviews.freebsd.org/D5492 |
