I am new to the boot loader sequence and I have few queries, which are mentioned below.
In Multi boot chain sequence, how the following are done,
1 ) Hash validation to validate the u-boot binary
2) Hash validation to validate the Linux kernel binary
What are the PPA services?
How does X-loader/u-boot invokes PPA to calculate the hash value of the u-boot binray/the Linux kernel binary.
What is PA API ? And how does PPA invokes PA API(SHA1MD5 function).
Please let me know as early as possible.
Rgds,
Pavan
