This data will be later used by bootloader in DDR PHY reconfiguration process. Also, in the process or recalibration the first 8 words of the memory may get corrupted. To solve this, these 8 words are saved in the securam and restored by bootloader in the process of PHY configuration.

It is now one of the last parts of arch/arm/ that fails to build with the clang integrated assembler, which is unlikely to ever want to support it. The two alternatives are to force the use of binutils/gas when building the crunch support, or to remove it entirely. According to Hartley Sweeten: "Martin Guy did a lot of work trying to get the maverick crunch working but I was never able to successfully use it for anything. It "kind" of works but depending on the EP93xx silicon revision there are still a number of hardware bugs that either give imprecise or garbage results. I have no problem with removing the kernel support for the maverick crunch." Unless someone else comes up with a good reason to keep it around, remove it now. This touches mostly the ep93xx platform, but removes a bit of code from ARM common ptrace and signal frame handling as well. If there are remaining users of MaverickCrunch, they can use LTS kernels for at least another five years before kernel support ends.

There is also the "loft" board which is just a Kconfi entry and which reuses the same boardfile. If there is interest in the Loft variant and someone is willing to test I can create a special DT superset for this board, which only differs in PCI set-up.
