      dt-bindings: nvmem: u-boot,env: add Broadcom's variant binding · 6b0584c1
      Rafał Miłecki authored
      Broadcom uses U-Boot for a lot of their bcmbca familiy chipsets. U-Boot
      stores its configuration in an environment data block.
      
      Such blocks are usually stored on flash as a separated partition at
      hardcoded address. Broadcom however decided to:
      1. Store env data block inside U-Boot partition
      2. Avoid sticking to hardcoded offsets
      3. Use custom header with "uEnv" magic and env data length
      
      Example (length 0x4000):
      $ hexdump -n 32 -C -s 0x40000 /dev/mtdblock0
      00040000  76 6e 45 75 00 40 00 00  34 89 7a 82 49 4d 41 47  |vnEu.@..4.z.IMAG|
      00040010  45 3d 4e 41 4e 44 3a 31  4d 2c 31 30 32 34 4d 00  |E=NAND:1M,1024M.|
      (0x40000 offset is unit specific and can change)
      
      Starting with the commit 118f3fbe ("dt-bindings: mtd: partitions:
      support label/name only partition") DT can describe partitions matching
      them by a name (without specifying actual address). With that feature
      and this binding change it's possible to:
      1. Specify DT node for Broadcom's U-Boot env data subpartition
      2. Add nodes for specific environment data variables
      3. Reference them as NVMEM cells
      
      This binding is unlikely to help Broadcom's U-Boot. U-Boot SPL needs to
      find environment data early (before it accesses DTB) and it does that by
      looking for an "uEnv" magic. Dirty way.
      
      This binding can however be used by operating systems. It allows
      describing cleanly U-Boot, its env data and variables. It tells
      operating system about Broadcom-specific env data so it can parse it.

      dt-bindings: mtd: partitions: u-boot: allow dynamic subpartitions · 4862a4d7
      Rafał Miłecki authored
      U-Boot partition may contain subpartitions. For example Broadcom
      includes environment data block in the middle of its U-Boot partition.
      
      This allows describing Broadcom's U-Boot env data and will allow
      referencing its NVMEM cell in the future.

      of: declare string literals const · 91924d9b
      Christian Göttsche authored
      of_overlay_action_name() returns a string literal from a function local
      array.  Modifying string literals is undefined behavior which usage of
      const pointer can avoid.  of_overlay_action_name() is currently only
      used once in overlay_notify() to print the returned value.
      
      While on it declare the data array const as well.

      Pull more random number generator updates from Jason Donenfeld:
       "This time with some large scale treewide cleanups.
      
        The intent of this pull is to clean up the way callers fetch random
        integers. The current rules for doing this right are:
      
         - If you want a secure or an insecure random u64, use get_random_u64()
      
         - If you want a secure or an insecure random u32, use get_random_u32()
      
           The old function prandom_u32() has been deprecated for a while
           now and is just a wrapper around get_random_u32(). Same for
           get_random_int().
      
         - If you want a secure or an insecure random u16, use get_random_u16()
      
         - If you want a secure or an insecure random u8, use get_random_u8()
      
         - If you want secure or insecure random bytes, use get_random_bytes().
      
           The old function prandom_bytes() has been deprecated for a while
           now and has long been a wrapper around get_random_bytes()
      
         - If you want a non-uniform random u32, u16, or u8 bounded by a
           certain open interval maximum, use prandom_u32_max()
      
           I say "non-uniform", because it doesn't do any rejection sampling
           or divisions. Hence, it stays within the prandom_*() namespace, not
           the get_random_*() namespace.
      
           I'm currently investigating a "uniform" function for 6.2. We'll see
           what comes of that.
      
        By applying these rules uniformly, we get several benefits:
      
         - By using prandom_u32_max() with an upper-bound that the compiler
           can prove at compile-time is ≤65536 or ≤256, internally
           get_random_u16() or get_random_u8() is used, which wastes fewer
           batched random bytes, and hence has higher throughput.
      
         - By using prandom_u32_max() instead of %, when the upper-bound is
           not a constant, division is still avoided, because
           prandom_u32_max() uses a faster multiplication-based trick instead.
      
         - By using get_random_u16() or get_random_u8() in cases where the
           return value is intended to indeed be a u16 or a u8, we waste fewer
           batched random bytes, and hence have higher throughput.
      
        This series was originally done by hand while I was on an airplane
        without Internet. Later, Kees and I worked on retroactively figuring
        out what could be done with Coccinelle and what had to be done
        manually, and then we split things up based on that.
      
        So while this touches a lot of files, the actual amount of code that's
        hand fiddled is comfortably small"
