• 556d2f055   ARM: 8187/1: add CONFIG_HAVE_ARCH_BITREVERSE to support rbit instruction ... Browse Code »

  this change add CONFIG_HAVE_ARCH_BITREVERSE config option,
  so that we can use some architecture's bitrev hardware instruction
  to do bitrev operation.

  Introduce __constant_bitrev* macro for constant bitrev operation.

  Change __bitrev16() __bitrev32() to be inline function,
  don't need export symbol for these tiny functions.

  This patch provides two bit reverse functions and bit reverse table.

  - reverse the order of bits in a u32 value

  u8 bitrev8(u8 x);

  - reverse the order of bits in a u32 value

  u32 bitrev32(u32 x);

  - byte reverse table

  const u8 byte_rev_table[256];
