Kumar Gala dd50af2515 powerpc/8xxx: Add hwconfig APIs to address early parsing used by DDR init ... There are several users of the hwconfig APIs (8xxx DDR) before we have the environment properly setup. This causes issues because of the numerous ways the environment might be accessed because of the non-volatile memory it might be stored in. Additionally the access might be so early that memory isn't even properly setup for us. Towards resolving these issues we provide versions of all the hwconfig APIs that can be passed in a buffer to parse and leave it to the caller to determine how to allocate and populate the buffer. We use the _f naming convention for these new APIs even though they are perfectly useable after relocation and the environment being ready. We also now warn if the non-f APIs are called before the environment is ready to allow users to address the issues. Finally, we convert the 8xxx DDR code to utilize the new APIs to hopefully address the issue once and for all. We have the 8xxx DDR code create a buffer on the stack and populate it via getenv_f().
