函数名称：vert ecc bytes to aligned, zero-padded 32-bit ecc words

函数原型：static void load_ecc8(struct bch_control *bch, uint32_t *dst, const uint8_t *src)

返回类型：void

参数：

类型参数名称
struct bch_control *bch
uint32_t *dst
const uint8_t *src
144  uint8_t pad[4] = {0, 0, 0, 0}
145  nwords等于BCH_ECC_WORDS(bch)减1
147  以i小于nwords循环dst[i]等于src[0]左移24位按位或src[1]左移16位按位或src[2]左移8位按位或src[3]
150  内存复制(pad, src, BCH_ECC_BYTES(bch) - 4 * nwords)
151  dst[nwords]等于pad[0]左移24位按位或pad[1]左移16位按位或pad[2]左移8位按位或pad[3]
