- * The first, qbman_sys_decl.h, includes any and all required system headers as

- * non-zero is TRUE, so must convert all non-zero inputs to 1, hence the "!!"
- * operator) into a register at bit location 0x00080000 (19 bits "in" from the

- * If you wish to read-modify-write a register, such that you leave the 14-bit
- * field as-is but have all other fields set to zero, then "i"solate the 14-bit
- * value using;
- * reg_value = i32_uint16_t(3, 14, reg_value);
- *
- * Alternatively, you could "r"emove the 1-bit boolean field (setting it to
- * zero) but leaving all other fields as-is;
- * reg_val = r32_int(19, 1, reg_value);
